What engine oil y'all running now?

[Bigvman54]

I know there are some previous threads on this, but most of them are pretty old and there's been a plethora of oil related info that has hit the Internet the past few years. I know I've watched literally hours and hours of oil related videos on YouTube recently. With that, who is running what oil these days? I have a 1996 with the 2.3 with about 250,000 miles on it and I've run a good quality synthetic since early on. I'm currently running Pensoil Ultra Platinum 5-W20 and have for a while, with Purolator Boss filter. 5-W30 was the recommended oil from the factory, but a TSB came out several years ago suggesting 5-W20 so I rolled with that. However, after watching some of the oil related videos on YouTube I mentioned above, I think I'm going to switch back to 5-W30 and quite possibly go with a cheaper, high milage brand, quite possibly Walmart Supertech synthetic. No harder than I drive my truck and only putting maybe 2-3,000 miles a year at most, I don't feel I need to spend the extra money on PUP (which I use in my other newer vehicles and will continue to), and from the info I've gathered recently Supertech synthetic advanced and high mileage are very fine oils and the additive packages complete with many of the well known national brands.

Valvoline 5w30 conventional every 3k miles up until like 300K. I started doing 2qts of conventional 5w-30 and 3qts of VR1 10w-30 after that. 325K and climbing more everyday.

I had two 300k+ 2.3s on this regiment until the one got swapped for a 5.0. Now that engine patiently waits to be swapped in as backup for the other incase of emergency lol

Rotella T6 15-40 in everything I own. I buy it in 5 gallon buckets. Have casters under the bucket and a hand pump/hose for filling

Oreilly 10w40, its cheap and apparently doesn't taste as good as 10w30.

I use whatever 5w30 I can get my hands on for the 4.0 trucks. Usually Supertech full synthetic with a NAPA Gold/Wix/FL1A filter. 5000 mile intervals, rotate tires at the same time every oil change.

F250 gets Mobil 1 5w20, 3000 mile changes, because it has a loaded trailer behind it 90% of its life.

The 302 powered trucks get either 5w30 or 10w30, which ever I have on hand, they don't care.

Wife's Honda gets Supertech 0-20 full synthetic but I may switch her over to 5w-20 here because I have a ton of it on hand.

Yard equipment - old stuff gets 30w - because I have a couple gallons of it on hand. Newer equipment usually gets 10w30, 10w40, or 15w40.

My old '88 with the 2.3 got literally whatever I grabbed first, that might have been two quarts of Mobil 1 5w30, a 30 year old quart of 10w40 and two quarts of who knows what because the labels were gone. It didn't care but it kinda started smoking on the thin stuff. My kid has it now and is treating it to Mobil 1 full sythetic stuff, lol
