I don’t disagree with you, I’d rather be putting synth amsoil in, but a point was made to me that it needed to be dino, was just bugging me I didn’t know why.

 

My dealership uses a synthetic blend 5W-30. Isn't that the same thing as Toyota Genuine Motor Oil?

 

anybody know of good sites to get oem parts for the 500?

 

I am old school and have no problem with Dino oils, but I would change every 3,000 miles. Some Dino oils vs synthetic are a little heavier grade for grade. Having said that, I run full synthetic 5w-30 Pennzoil Ultra Platinum with a Toyota/Lexus oil filter and will still never go more than 5,000 for the oil change interval. I will actually more than likely change it closer to 3,000 than 5,000. Lastly, I will NEVER use a non API approved oil in anything with a warranty. Once warranty is up, there are some great oils out there like Amsoil Signiture Series that lack the API certification that I'd use.

 

Toyota Genuine is traditional, from my understanding.

 

OK well my dealership put in a synthetic blend. Not sure what else it would be if not TGMO.

It's kind of a moot point. We all know full synthetic is best.

 

At our dealer, you have a choice between Toyota Genuine, and Mobil1.
