Hey Everyone, My local salesperson says the dealership uses semi-synthetic oil. I am sure it is supposed to be 0W20 motor oil and I wasn't aware you could get that in anything besides synthetic. I'm hoping he was wrong and misinformed and they use synthetic. If not, I may just take my Mobil 1 0W20 to them and have them use that instead....
Maybe he is using semi-knowledge or maybe the dealership is using the stuff they buy in 50-gallon barrels which could be anything. AFAIK, 0W20 is synthetic, and that's what's best for the engine to go 10K miles before the next scheduled oil service. I bring a 5-QT MobilOne container and tell them to use that in my car. I am really hoping that is what they have used.
Thanks. That is exactly what I thought. I only use Mobil 1 in my vehicles and I sure hope they change my oil using synthetic. If that is what is recommended, that is what they should be using.
i would expect all the dealership's to use toyota approved lubricant's. but that may be expecting too much.
By "semi-synthetic" does he mean they are using a synth-dino blend, or a "fake" synthetic (e.g. Group III) oil? Is Mobil 1 still made from Group IV?
First off, if it's 0W20, it likely (if not conclusively) is synthetic. Still, my take: if it's "0W20", and a quality oil, that's all that matters.
Would the dealership care/dare to show you the oil they're filling your car with, if you ask nicely? If they can't prove it, or won't show you, then bring your own oil.
