Saw a few reports recently from people with NON-oil burning Theta II's who ran Quaker State Ultimate Protection or Quaker State Ultimate Durability (one switched to Euro oils but had a lot of miles on Quaker State Ultimate Durability). Keeping one of those Theta engines from burning is about the best endorsement I can think of for an oil.
Quaker State???? Any good?

Quaker State Euro was well liked on a German car forum I used to peruse.
I retract my earlier statement.... Amazon didn't completely DIS me... They ended up shipping me 3 of the 6 gallons I ordered. Three gallons is better than zero gallons.
When the time comes, I think I will be using it in my Jeep Wrangler with 2.0L Turbo.

Quaker State Ultimate Durability was the "recommended" oil in my 2015 Hyundai Sonata and what I started off using. And the research I did at that time pretty much stated it was a very good oil, and it was usually cheaper than competing brands too, so good all the way around. However I ultimately switched to Pennzoil Ultra Platinum, and have now just today gone to Valvoline Restore and Protect with my latest oil change. With that said I think the Quaker State ultimate durability or whatever it is they go by now is good oil and I believe has the same base stock of GTL that Pennzoil Ultra Platinum has.
But then why did you go with PUP and VRP after that when Quaker State Ultimate is not a worse oil and also is cheaper?
