My truck uses Chevy's direct inject 3.6 with timing chains. There are plenty of stories over the internet of timing chain stretch on these engines. Most "experts" attribute that to too long OCIs and dirty oil.
I like to keep my vehicles for forever, and a timing chain job is not something I want to undertake.
I figure selecting an oil with the absolute best anti-wear properties, and frequent OCIs is my best defense against timing chain stretch.
I recognize any oil meeting the dexos spec should be sufficient, but certainly some oils are better than others specifically for anti wear.
Thoughts?
