Colorado Turbo 2.7L Oil Question Quakerstate vs Pennzoil

[cb4017]

Same engine in my 23 Colorado ZR2. I've done two oil changes on it so far with Blackstone UOAs (listed in that forum).

First oil change was QS FS. It did great. Second was M1 EP. It also did great on that. I'll probably stick with M1 EP and 5K OCIs.

I thought the new Quakerstate UP was using a GTL blend now as well ?

I haven't read anything in that regard around this site. If you find the source, please revisit this thread..

Think the outcome was the data sheet shows it does but they can use any group III in place of GTL. So it might or might not.

General practice with SOPUS seems to be that if GTL is mentioned on the quart or jug bottle, it's in the formulation.
I haven't seen such on any Quaker State jugs to-date.
