Engine oil Mobil or AMSOIL

I recommend using Mobil1 engine oil. It contains additives that extend your engine life. I’ve done a teardown of a Skyactiv engine that used Mobil1 and one that used Pennzoil. The Mobil1 engine looked a lot better than the Pennzoil one. I use it in my parents’ CX-9, no problems at all.

I own a 2019 N and have used mobile 1 synthetic 0W-30, subs i bought it. this will be my 5th oil change as i change mine every 8000 miles. So far no problems.

I only run Amsoil in everything I own from cars to lawnmowers. I use their signature series, but with the 0W-16 they only have their regular blend.

I used mobile 1 for the rav 4. Factory fill on the evo was mobile 1

i used the original oil (0w20) but here in mexico is a little expensive. change the oil to mobil 10w30 full synthetic and works great on my fit 2010.

I like Amsoil. A lot of guys swear by Shell Rotella T6.

In all seriousness, Mobil 1 5w-30. Ran it for 70k in my '14 and so far 54k in my '18; zero problems.

I have never used anything but Amsoil in my LB7 Duramax for 12 years. It has almost 350,000 miles on it. I use Amsoil in everything from the weedeater right on up to the Duramax. Never one issue, and I only change it about every 20,000 miles.

I keep using AMSoil after seeing a test results sheet from Blackstone (i think thats the labs name) for my 6.0. Tested after 15k miles and was better than 400 mile motorcraft.

I've used 15w50 Mobil 1 with no problems. It wasn't bad. It acctually good. But, it didn't make one bit difference, so I've used it only once, and went back to the regular 0w40 Mobil 1.
