Engine oil Mobil or Motorcraft
Mobile 1 syn. doesn’t burn any yet. Never had issues with it.
Mobil 1 5w30 Annual advanced synthetic. We have a garage full of Mustangs heavily modified...all on Mobil 1 full synthetic...always. No engine, turbo, or supercharger issues on these cars as well.
Mobil 1 with no issues change every 3k, rarely top off in between changes
Mobile one is best in every single case, unfortunately its the most expensive for this reason.
I’ve heard valvoline is good too. I use Mobil 1
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.
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.
