I’ve got a 2024 Chevy Trax with the rubber timing belt in oil and gasoline direct injection (& turbo charged) If I drive 12,000 miles per year ( a good bit of it short trips ) I’m concerned about gasoline in oil contamination and it’s effect on the rubber belt. If I budget appropriately $100 a year…

Can you explain this “rubber timing belt in oil”? I have never heard of getting oil on a rubber timing belt intentionally.

Use the oil specified on the oil cap which is Dexos Follow the owners manual for the oil change interval. Simple. Tester

Imagine a rubber belt in place of your typical timing chain. Scary.

“Remember the manufacturer may not have the same objectives as you” BINGO! George. Their concern might only be making the 5 year 60,000 mile mark and not the 150,000 mile rubber ( interference type engine) timing belt change interval.

Cut that recommended oil change interval in half for your own good. If it says 12,000, change at 6,000. Change my mind. 520k, 480k, 320k, 240k etc. with nary an engine problem except for the diesel.

Forget the Amsoil. I’d use a name brand oil that meets the Dexos spec, change it more often if you want.
