Engine oil Mobil or AMSOIL

I just put Amsoil High Mileage, 0w20 in my 2012 Camry to see if it will benefit my engine with 221,000 on it. I switched from Mobil 1, which I used for years changing at 5K intervals, but had to keep topping off very often. The engine flush was excellent, the oil I drained only had 1500 miles on it and it came out looking like liquid coal! So a cleaning did take place, I'll see how it goes.

I've been using Mobil 1 10w30 regular and now High-Mileage Synthetic for decades and most of the Jeeps life.

There’s been a lot of advancements in oils since the YJ was new. I use Mobil 1 0w40 in mine due to its excellent temperature range and proven endurance.

Mobile 1 full synthetic 0W-20 every 5K. My engine hums like a top.

Oil changes are cheap enough now that Mobil1 ESP 0w-30/5w-30 which is Approved by VW as 507 spec is around $28 per jug at Walmart. I'd change it more frequently and not chance it on the 2015 TDI engines in USA.

CKRA Passat, 164k miles, every 10k miles oil changes since new without negative experience. I did a Blackstone report once and oil looked good. I have used Rowe, Liquimoly, Fuchs and Mobil1 ESP.

Mobil 1 is a fantastic oil.

I have 265k on my 2002 Weekender purchased new. Run Mobil-1 0W-40. No problems with engine but transmission needs TLC.

I will say I've done my last 3 oil changes with penzoil platinum and my engine rode rougher and louder than it did before with the Toyota oem oil. So this past time I tried mobil 1 and it's way quieter and rives smoother.

I'm running Amsoil 5w40 or Castrol Syntec 5w40. I ran Mobil1 10W30 a few times and I heard too much valve noise. When I opened the oil cap after driving around on the freeway it was smoking..which I'm not all that happy about. So I stopped using this oil.
