I've used Valvoline for 4,200 miles consecutively. And then I used Quaker State for 6,800 miles consecutively. Right now I'm working on a record of Mobil 1, but so far it has only been a consecutive count of 5,837 miles.

In the 60s and 70s Penz and QS had the reputation of being sludge prone oils, deserved or not. However in the 60s I used QS in a nearly new Valient slant 6 and in 50K it sludged really bad, and that was with 2K OCIs.

Oh. Alright. That explains alot. I was at Walmart adding to my stash of PP a couple of months ago and I had an older gent ask why I was buying so many jugs of pennzoil. I of course stated its one of the best oils out there and 23 bucks a jug and he said it will sludge my engine. He also said the same about castrol.
We chatted for a while as we waited to pay. He's a farmer,I'd guess around 80 or so.
He told me that synthetic oil is a scam and its just regular oil re-labelled. At that point I quit lending any credence to what he was saying. He did say he was a valvoline guy though. I figured it was best not to bring up next gen. If he thought syn was a scam I didn't want the poor old fella to snap a breaker trying to compute that process.
Thanks for the info Tig. It's amusing to still hear these old notions still pop up.

EXPOSED!!!!
Mobil would be smart to employ him. He uses his own equipment as a test bed for their products,he is brand loyal and his engines have only ever gotten M1 so any data would be exclusive to M1. Such as if there were deposits or anything of that nature. It can't be blamed on using something else for a few runs.
He isn't pushy,he posts relevant pics and has actual knowledge behind his answers,he isn't reading pre-written answers and since he bought his vehicles new,and have only used M1 it eliminates many variables.
Me on the other hand switch up every interval,I mix various grades and additives and change it usually too early. I'm the poster child for what not to do as far as vehicle maintenance but in my lifetime I've only had 2 engine failures. My first was a 305 in an 83 cutlass. It turned the cam into a cornstalk and a ford 2v from my mustang which was fords fault.
