No Full Synthetic Oil in the Z?

Metal shavings...no ****. Physics...man, physics...

Your cylinders are honed into a file-like crosshatch pattern when new, and when the engine is first fired up (with oil in it), they "file" down everything and get the rings seated.

And where do those shavings go? Into the pan, with the oil, that ships with your car that you drain out at your first change, and some shavings stay in the engine because you can't get them all out...so they're there until you're ran enough oil through the engine and filter...

Also numerous cars come with synthetic oil from the factory...nothing wrong with using synthetic from the moment you get a new car home, drop the oil out of the pan, and refill it...


Also, in chosing the correct oil - if it meets Nissan's spec in the manual (I don't remember what it is, but it's common) - Nissan can not deny a warranty claim over it. You don't have to use Nissan's oil. There is no "but I think it'll be fine" - fact is, it will be fine.

Nissan can recommend you use Nissan air filters and oil filters too, but that doesn't mean anything - they're just trying to get you to buy something they have a mark-up for, instead of what could potentially be better for your car.

Case and point - Nissan Ester oil - is it synthetic or not? Is it Group III, Group IV, or Group V...?


And the bike shop didn't "laugh" at me...they wanted me to buy their oil, and take OUT the synthetic. Sound familiar?
