Engine oil Mobil or FUCHS

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.

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.

used mobil 5W-30 while ago, discovered it consume oil too fast. after that i’m stick with seasons cheapest LL01 approved oil. Elf 900FT 5W-40 for several years, going to try Penzoil 5W-40. N52 consume oil anyways.. but bit slower than 5W-30.

I tried Mobil 1 in a Vortec 5.7. That engine did not use oil using Castrol or even Walmart dino oil. IT did use a quart at 1000 miles using 15-40 maybe it was 15-50 Mobil 1.
