Engine oil Mobil or FUCHS

Do not cheap out on oil. I use Mobil 1 high mileage but Castrol is also good.

I've been using Mobil 1 0w-30 AFE in my VN for over 18000 miles now. No issues and runs fine.

I just rolled over 200,000 in my 2011 5.7. I change mine every 5,000 miles with Mobil 1 Full Synthetic High Mileage 0W-20.

Mobil1 V-Twin 20W-50 in all three holes.

I heard you can throw 20W-50 (Synthetic, specifically V-Twin Mobil One brand) in all three holes and have no issues.

Mobil1 x1 1000 15w40 in all my cars. My engines are clean and quiet, oil pick-ups don't clog, there's a nice permanent oil coating everywhere.

I'm apparently the least informed person here (never done an oil analysis), but FWIW I seem to be fine with Mobil-1 0w40 on a 996.2 with 208k miles.

Mobil 1 5w50. Temperate climate. Car always garaged. Annual changes at 4000 miles. Zero top ups required.

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 have been running Mobil 1 0w-40 since new with over 50k miles on different Big turbo(80k total miles) setups and always replacing seals and gaskets due to oil leaks(its some really thin oil).
