Synthetic vs Conventional Oil in St. James, NY
When your car is due for an oil change, somethign you might want to know if itās your first time getting this form of maintenance is what type of oil it needs. Most often, synthetic or conventional oil will be the answer, but it differs from model to model. Our Lexus of Smithtown team has put together this short guide to help you get started, so read on!
Synthetic Oil
The purpose of synthetic oil is to provide vehicles with a longer lasting solution for their engine oil needs. This fluid is what most high-intensity engines require to function at their best, so if your drives to Gaynor Park are spearheaded by a fairly recently released car, then it most likely uses synthetic oil. Because you can get more mileage out of this option, you wonāt have to seek out an oil change as frequently. However, the trade off for its excellent long-term performance is that itās a more expensive option.
Conventional Oil
Acting as a contrast to synthetic oils longevity and premium cost, conventional oil is the go-to choice for cars that run with an older powertrain. Part of the reason behind this is that the engineering of these motors is far better suited to handling the crudeness of conventional oil. Of course, being an antithesis to synthetic oil, youāll find that conventional oil is as adept at performing for extended periods. Youāll have to schedule an oil change appointment at our Service Department more regularly, but the cost of this maintenance wonāt be as high as it would if you were to require synthetic oil.
Which Is Better for Your Vehicle?
If you have a newly released luxury SUV thatās come fresh off the factory to handle your family trips to the Moriches Soccer park, then youāre going to be looking for synthetic oil to keep it performing up to standard. On the other hand, if youāve got a pickup truck from years past thatās seen its fair share of time on the road, but still has plenty of quality miles left to give, then conventional oil will serve it best. We always recommend consulting the Ownerās Manual of the model that you drive as well, because thatās where youāll be able to find the most accurate information regarding the type of oil it needs. Weāre more than happy to chat with you about types of oil and oil changes as much as you like, so reach out to us at your convenience!

“ I bought my beautiful new electric car today from Lexus of Smithtown!! Our first Lexus! I was debating between several models and car makers. We had visited several car dealers before Lexus of Smithtown. The Lexus was in my top 3 when I walked into the dealership, but after seeing the car options, related price tag, and financing option, the Lexus was my only choice ! Carlos from Lexus of Smithtown was instrumental in helping me make my decision. He managed the whole process including the return of my lease to BMW. Not the typical 'Car Salesman'. He was transparent and knowledgeable about all the Lexus models and other car maker models too! From the moment I spoke to him on the phone, to the moment I arrived in the showroom and found pre-heated cars for me to test drive to the moment I arrived home, Carlos helped each step of the way! He is committed to his customers and goes the extra mile! I cannot speak highly enough of Carlos. He was even washing and wiping down my returned BMW so it would look great for the lease return. SERVICE SERVICE SERVICE! Everyone at the dealership was outstanding. There was no sales pressure, everyone listened to our thoughts and concerns and provided honest feedback. We even got a great deal and great interest rate š From Carlos, to the sales manager Phil, to the Finance Manager Dominique, the Tech rep Omar, Matt that helped work out my name mismatches, and the other sales representatives that took a few minutes to talk to us while we waited, everyone at Lexus of Smithtown was helpful, knowledgeable, and pleasant! I highly recommend Lexus of Smithtown and donāt forget to ask for Carlos! ”
“ The whole car buying experience was great. Working with experienced sales associates that can guide you through the process makes such a difference. Much of the team has been with this company a long time. That says a lot. Employees that are treated well will in turn pass that on to customers. ”
“ Shawn made my car-buying experience incredible. He was completely transparent with the numbers, with no hidden fees or last-minute changes to my payment. His persistence, honesty, and customer service were unmatchedāeasily the best Iāve ever experienced at a dealership. I canāt recommend Shawn enough. ”
“ Lexus of Smithtown is the best dealership to get your car. Carlos helped me out with purchasing my first Lexus and honestly made it a very smooth process. He is an amazing person to work with and Iām honestly so happy overall! I will be back to purchase more cars from Lexus of Smithtown. ”

“ Excellent experience at Lexus of Smithtown with my new 2026 RX 350 AWD Premium Plus. Huge thanks to Gloriana and Dominique for the smooth and great service. From start to finish, everything was handled professionally and efficiently. They made the entire process easy and stress-free. Highly recommended- Many Thanks!! ”
“ Gloriana, the woman who sold us the car, was amazing, as was the entire staff at Smithtown Lexus. From the moment we walked in the door, they were welcoming and allowed my wife and I a chance to just look at different cars in the showroom without annoying us. When we were ready to test drive, Gloriana took us several times as we were indecisive. Car sales people usually steer you towards the more expensive car to make more commission. To our surprise Gloriana told us she sees my wife in the smaller SUV, which was what we were thinking as well, and was also less money. This honestly was the best car leasing experience I have had in 30 years. We will definitely go back to Smithtown when our lease is up for another Lexus. If you are thinking about a Lexus and want it to be a really easy and amazing experience, I would recommend going to Smithtown Lexus and seeing for yourself. ”
“ I recently bought car from this dealership. Brother Usman provided phenomenal service. I am really appreciate brother Usman for smooth process everything. I am highly recommend this place to have your dream car. ”

Very knowledgeable and understanding. Went above board to find the color we wanted and was so helpful from start to finish. Give him 15 stars. And Denise in Finance was GREAT as always. It is always an exciting and pleasurable experience working with this dealership. ”
“ I had an excellent experience working with Sean at Lexus. As a physician with a busy schedule, I appreciated his professionalism, knowledge, and patience in helping me find the perfect car.

He truly made the car-buying experience enjoyable, and I highly recommend him to anyone looking for top-notch service and guidance. ”

“ Great experience with Carlos! ”
“ Caleb is the absolute man. I went to three different dealerships, he wasnt pushy, knew the cars and got us a great deal. Get pricing from another dealership,then call smithtown and ask for Caleb. Show him the numbers and buy from him. Hands down the the best experience we've had. ”
“ couple days ago I took my Lexus UX to get serviced,,Ruben reached out to me about the great December to Remember deals tgat they had. went in to check them out, Ruben and his sales manager Caleb listened to my concerns and work out a deal that made me very comfortable,actually too comfortable like it was too good to be true. Before you know it I was out of my Lexus UX and into my dream truck(RX350H),they both were very knowledgeable and made this experience very smooth. Thanks you very much fellas. you guys rock. if anyone looking for a great deal on Lexus,I strongly recommend Ruben and Caleb from Lexus of smithtown. ”
Great experience with the first service of my RX350.
“ Great experience with the first service of my RX350. Also, amazing help from Jerry the tech guru. He was kind, knowledgeable, patient, and simply wonderful. He carefully explained the nuances of the technology and never once made me feel as though I was foolish. Thanks Jerry, best of luck to you. ”
“ Today, 12/16/25 I had my 5K service at Lexus of Smithtown. The staff was friendly, efficient, and extremely thorough. My car was serviced in a timely manner and I was very pleased with the service from beginning to end. But the real treat was my experience with the "Tech" advisor Gerry (hopefully I spelled his name correctly). Gerry was so patient, helpful, friendly, kind and extremely knowledgeable. I never felt rushed, or made to feel foolish for not understanding the intricate systems of my wonderful Rx350. The experience with Gerry is just another reason why this dealership is so wonderful. Thanks, Gerry for all your help today and thanks to the Service Department for a job well done. ”
“ I just picked up my 4th RX 350..All were purchased (or leased) from Smithtown, and all experiences were fabulous BUT this one was a definite standout! While there were several wonderful people involved in the entire process, 2 people were amazing! The salesman, Fahad, managed the process like a true professional and like a really friend at the same time! After driving the car a bit, I had a list of technology questions and so I went back and met with Gerry.. Iām not sure that I have ever met a more patient and kind person! ( I canāt imagine what his day-to-day dealings are!) Even when I called the next day with an issue that I couldnāt remember how to manage ..it was like talking to my best friend who had nothing else in the world to do (and Iām sure he did have plenty to do!) All in all, my experience at Smithtown Lexus was just outstanding!! Thank you, Lexus of Smithtown! ”
“ The entire experience from beginning to end was flawless. We are a Lexus family, however, we have never had such a positive experience purchasing a car as we did with Lexus of Smithtown with Carlos as our sales representative. The entire process was stress-free. When we arrived to pick up our car, we were told that Carlos was with the detailing team, making sure that everything was perfect. And it was! When he took us out to see the car, he surprised me with putting a big red bow on it! That put the biggest smile on my face. Explaining the tech to me was done in a patient, and easy manner so that I was able to grasp it right away. Thank you, Carlos and the entire staff at Lexus of Smithtown for making this process so easy! We will definitely be returning customers. ”
“ Excellent shopping then buying experience from start to finish. ”
“ Professional, transparent, kind and friendly. Had a great experience with Ethan and Caleb! Very happy with my new car! ”
“ This is my 2nd time getting my car service at this location and my last. Michelle Stokes my service advisor the only individual that speaks and is very professional everyone else there just walk by you like theyāre celebrities or donāt even greet you. Iām not saying to walk around smiling all day at least acknowledge the people that keeps the light And heat running in the dealership ”
“ When I called to report my battery dying immediately following Lexus service appt (oil change, NYS inspection, tire rotation and car wash) and I suggested it was very curious to me that the day prior there were so many āLexus eyes and handsā working on my car and then suddenly my battery dies and as luck would have it - the day before a blizzard! Now thereās no way of knowing for sure, but the least I wouldāve expected from the manager of a luxury car dealership ( who Iāve been going to for all of my services and never had a problem) suddenly takes a very defensive tone with me and says are you accusing us of doing something? No, Iām not accusing you Iām simply calling you to let you know that the timing is questionable and it is possible that someone during service left a wire lose or failed to close accessory light, or door etc. and put me at higher risk of battery dying. I was lucky enough to be able, even though it was the evening the next day when I discovered it to get a battery and have it installed! I donāt even wanna think what wouldāve happened if I woke up with my car buried as it was from the blizzard and then also to have my battery dead on top of that! What upset me more than the fact that it is very possible that it was just my batteryās time to die - was the tone of the conversation with this manager, and his reaction to my concerns, and the way he seemed disturbingly comfortable with speaking to me the way he did (and he didnāt even realize his tone - which is scarier), even after I told him I have health issues and certainly did not like the way he spoke to me and the tone of the conversation, and it could actually affect my health in a negative way. Yet he still took no accountability and apparently is not trained in how to handle customer concerns and had the nerve to then accuse me of accusing them of nefarious behavior! I found his tone dismissive, smug, and a bit on the man-splaining side telling me that batteries eventually die! (Really? I had no idea! SMH) my point is the timing - again totally normal that myself and a few family members and friends also found it a little sus. But this āmanagerā felt ok with trying to talk over me, gaslight me, and told me basically āHey batteries die, and it wouldāve cost just as much to buy it from Lexus or from somewhere else so what are you gonna do?ā Very cavalier and dismissive. You can accuse me of accusing you, yet did you ever put yourself in a customers shoes that why wouldnāt it cross my mind that maybe you wanted me to buy a basic model battery from you at the higher model price (+ labor) that I got from an outside vendor, who didnāt charge me installation? This is a normal human reaction to think hmmm the timing is very weird here let me give them a call. And maybe, just maybe since they knew, I told them that day no other service needs to be done Iām on a tight budget right now, but since I always came to them for servicing that I would turn around and come back and buy a battery from them?! I think as a customer, itās okay for me to question these things⦠and also question why is he going immediately on the defensive instead of just saying something like āWe are so sorry that happened, and although we are very careful when we service our customers cars and since we appreciate your business and you as a loyal Lexus owner, maybe thereās something that we can do for the inconvenience that this caused you.ā Or at the very least BE NICE on the phone to a customer! IMO Smithtown Lexus needs to have customer service training with their managerial staff specifically... So the problem is apparently from the top that maybe some customer service workshops would come in handy. As the saying goesā¦āItās not what you say, itās how you say it.ā I will no longer be using Lexus Smithtown for servicing my car. ”
“ Service department person on the call just hanged up while I was talking. And she was very unprofessional and was in rush during the whole time i was in the call. Very unprofessional and frustrating! ”
“ Beware!! Had my Lexus appraised a month ago at this store, was told they would give me a 1,000 Dollars in Equity my car had, that they would put towards my New Lexus, well come to find out, another appraised amount (through someone else) was $ 10,000 in equity because the 2021 that I have only has 35,000 miles on it, So the sales manager says when I called ā thats what we just decided to give youā that just shows the Greed of this store. and then he hangs up on my face, so considering I had purchased 4 Lexusās from this store and any future business is now lost, because of Greed, and just imagine the amount of money will be lost in example another 10 years of payments on future cars, Thanks So much. Merry Christmas A great lesson learned, Dont Trust Your Appraisal from this Store! Jason Caldeira ”
“ I was hopeful that this dealership would be honest, but not the case. I leased a 2025 RX350 in October 2025. I went back a forth several time with a young girl because the person I was dealing with previously left. I was not able to get there during daylight to pick up the car. I did not see it before the day of pick up because the specific color combo was not onsite. They showed me the exact same truck just different exterior color. Ok. So I get there at night and the truck was parked with the red distraction bow. I sign papers (first mistake) then I went outside with the tech person. First thing I notice is the mileage of 1600 miles. they assure me this is normal itās due to transportation of vehicle. This is the first time I leased so I did not have time to research. Rush through everything. I drive home in the dark. Wake up the next day and notice some small scratches and dog paw prints on the seats and the middle console. When I call the sales girl she couldnāt care less now. She now says the owner used the truck for a bit. So this is acceptable? She flippantly said just bring it in and weāll clean it again. I said I canāt wait there for this. She has no other solution. I would never have accepted this vehicle. ”


“ Bought a used car in beautiful condition from this dealership. Wonderful customer service, Hamza & Caleb were so helpful during this process. This was the best experience I have ever had at a dealership. 10/10 recommend buying a vehicle here! ”
