Engine oil Mobil or Pentosin

I personally lean towards affordability, so I run Mobil 1 0w-40 because the local parts stores run sales for $35-40 pretty regularly.

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.

I put Mobile1 0w-40 in mine, even though it's not vw certified

I was running it in a VR6 engine, and couldn't believe how much extra chain and lifter noise there was. I put up with it for a couple weeks, thinking it might get better but it didn't, so I switched to Castrol Edge 5w-40 and noticed the difference immediately. Noise means wear, so I feel comfortable staying away from M1 for my VR6 engines.
