Question about synthetic oil
In my previous vehicle, a '00 Buick Regal GS, I changed the oil every 3,000 to 4,000 miles with Mobil One 10w 30 synthetic. When I brought my TL-S into the Acura dealership for an oil change, they told me that they will not use synthetic oil, and that if I really want to use synthetic, I would have to purchase the oil and bring it to dealership at the time of the next scheduled oil change.
I plan to follow the maintenance schedule and have my oil changed every 3,750 miles. What are your views on synthetic oil? Should I even bother to use it if I plan to faithfully adhere to my maintenance schedule?
Any insight would be appreciated.

A guy I know (who is a retired DOD aircraft engineer) swears by Mobil1 Synthetic and has not had a single problem in any of his cars (has owned over 200 cars, buys/sells every couple of months). I'm buying a 01' Acura CL-S (2dr) from him and plan to follow through and use Mobil1 Syn. He is a big vette guy and loves to talk about engines!

I just did my first oil change .... (do it yourself) Mobil 1 5w30 with a Mobil 1 filter ............ the dealership tech will take you oil and use it in his own car .....

Unless you can actually watch the dealer pour your synth oil in your car, i wouldn't bring that oil to the dealer and expect their trustworthiness on it. Someone's gonna take your nice oil and pour in cheapies instead...how u gonna know?

Changing synoil at 3750 is reall wasteful. I would go with the 7500 interval. That is what I do with syn in my cars, except the Cobra, where 6 months elapse before I get even 2000 miles.
Today's quality mineral oils are hydrocracked, with many of the lubrication properties of syns, at a fraction of the cost. If you are set on 3750, I would use mineral oil + one quart of Mobil 1, unless you routinely tow in hot weather or live in Alaska or North Dakota or some other unGodly cold habitat. If you do use a mineral oil, stay away from 5w20, go with 5w30 or if the temps stay above 0 year round, go with 10w30.
