Dexos 1 oil for a Buick

Sure - as soon as you reimburse me for the time spent doing so.

Seriously though, if you have a specific question, I'll help however I can. As for one example though, to your earlier statement, here's specific info on the GM turbo test, and what standards they have to meet: http://imgur.com/vwdyoze

Actually what I like to know, about DEXOS, is there something out of ordinary comparing to other standards. In other words, is it only a Marketing thing or there are really specific tests in DEXOS that are not performed in other standards.

You might surf this website.
It's got everything including a 132 page manual for building the engine for the Oxidation and Deposit Test.
If you want more info than that, you probably need to get a job at Lubrizol.


For some reason the link didn't post the first time:
