awesome statement. And as you might know, I change my oil (full synthetic) between 1500 and 2500 miles at the most). gives me something to do. For $30 or so, it’s easy and I know the oil is clean. I use Super Tech at wally world, castrol edge/gtx, quaker state, pennzoil and even royal purple (that was awesome oil and performance for 2K).
I’m guessing you get a lot of miles of use from your engines. Maybe a million?
Wow. That’s pretty extreme. But hey - the each their own, and if it gives you something to do then maybe it’s keeping you out of trouble. 
Well I got 520,000 with my Buick with 3000 mile changes with Dino oil. Just sayin. 100k, just broken in.
I didn’t say they didn’t make it. I just said I haven’t seen it. I NEVER check oil at Advance Auto. I only go there for things like Wax and cleaners. But Walmart, Oreilly’s and even NAPA only have synthetic on their shelves.
Yes sir you sure enough did say it, You clearly said ALL multi-viscosity oil is synthetic… Not some, not most, not even 99%, you said ALL… Sorry, but when you are wrong you are wrong, I am man enough to admit when I am wrong, Hell I even own it… How about you??
And THAT is what blanket statement I was referring to, Not you haven’t seen any…
That’s definitely different from the Walmarts in my area, where they stock conventional Quaker State & Castrol*, and a few synthetic blends.
*Edited to include 5w-30 and 10w30
That’s true…I should have been more specific. All multi-viscosity oil I’ve SEEN on shelves is synthetic. I have seen straight weight conventional oil. But many stores aren’t selling conventional oil anymore. Not sure why.
Dyno oil and blends ARE getting harder and harder to find, kind a like ATF type F, but if you look hard enough it is still being made…
But Pennzoil (Gold) still makes 0W20 in a blend, My work (retired) went to Pennzoil when ever that idiot Stu was hired on as the CEO (didn’t last long) came in and tried to make us like Jiffy Lube (idiot), glad that crap went away with him, but still stuck with Pennzoil, anyway, I have used Blend 0W20 in my daughters Toyota, but it is changed ever 5K not at the recommended 10K no matter if full or blend… But my fun car has only had pure Dyno oil Castrol GTX since day one of the engine build…
I change oil in my toyota every 5k miles and I use full synthetic. I don’t trust those 10k oil change intervals.
I’ve maintained 3 vehicles on strictly dyno oil over 300k miles. My 90 Pathfinder did start to burn a little oil toward the end. About 3 years after I purchased my 98 Pathfinder I switched to synthetic. That vehicle didn’t start to burn any oil until well past 400k miles and even then, it was less than a quart every 5k miles.
My fun car (just purchased since I retired) is a 2017 Vette Stingray. It requires full synthetic 5w-30 or 0w-40 - dexos certified.

I use full synthetic on all of our cars and just change it at 5K intervals
easy to remember
and I also perform the full services, every 5K
