Syn Oil 5w-30? I guess next time I should request regular oil. Since I don't trust synthetics on the rev ups. Unless it's just a weird description.

1st oil change


2nd oil change


Whereas Cerritos invoice shows "Semi Synthetic" Oil

 

Once you're using synthetic I wouldn't switch back to Dino oil. Regardless what you've heard synthetic is good for your Revup motor. I wouldn't use it for the first 4K miles but after that synthetic the best thing for any engine, runs cooler and lubricates better!
