Engine oil Mobil or Shell

I had a tiny bit blue smoke and thought it was sticky rings.

Ran mobil1 5/30 and it's gone.

Personally I've mostly been using Mobil 1 15w50, as it's almost never run in the winter.

Mobile one full synthetic hands-down. I have a 2004 Toyota Corolla and a 2007 Toyota Tacoma I’ve owned both since brand new and now both have over 260,000 miles apiece . I have only used Mobil one full synthetic changed every 5000 miles. just took a bore scope to look into both engines a few months ago. They look like they’re brand new. Almost no varnish. Absolutely no sledge, never had any problems whatsoever with these vehicles. It’s insane.

my vehicles use only Mobil 1 oil.

I have used Motul and Castrol before and I found the Mobil oil to perform and keep the engine cooler and smoother on my triumph.

Mobil 5w-40 or Liquimoly. 10w-60 for hot summer track days.

Mobil 1 AFE 0W-30 is what they used at the dealership and I’ve read a bunch of other people use it. I use it. Supposedly better than the mopar one.

Mobil1 or Pennzoil is what I use I got my car since 2019 no oil leaks no problems

Everyone has their preferences, at the end of the day it doesn't really matter, just change it regularly. I've used Mobil1, Pennzoil, LiquiMoly, Royal Purple, Rotella and probably a couple others I'm forgetting. No noticeable difference between any of them.

I used to use M1 0-40 in my VR6 Corrado, but the valve, chains and engine noise went way up, especially at a cold start
