Engine oil Mobil or AMSOIL

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.

I am a big fan of amsoil. I purchased a used F150 in 2012 . It had 80,000 miles. The first thing I did was I changed the engine oil, tyranny fluid, and front and rear end lubs to Amsoil. It now has 242,000 miles and just keeps on running.

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

5w40 if its drinking oil during vtec, I usually use Mobil but get whatever cheapest

I used US Mobil 1 0W-40 in my old 1.8T (mk4). I used it for two changes (finished off a box) and always found it was burnt at only 3k miles. You could smell it as soon as I pulled the dipstick out.
