Engine oil Mobil or AMSOIL

used Amsoil 5w20 last oil change and just did an oil change at ford with motorcraft due to my poor planning… typewriter tick is back with this oil. Didn’t have that at all with Amsoil.

Mobil1 especially the ESP 5W30, it has certifications from major manufacturers such as MB229, BMW LL, and importantly Porsche C30 certified which is the most strict out there... Also can't be helped that I own a Peugeot which happens to recommend Mobil 1 as well...

12 years running and no major issues so far on the unreliable-ass Prince EP6 Engine.

Having recently transitioned from Motul 7100 to Amsoil Metric 10W40 for my Yamaha MT 15, for about 4000km I sought an oil that could deliver reliable engine protection and smooth operation. here are my pros and cons

‘15 here and I use Mobil 1 0w40 euro spec or whatever it is.

I change mine about every 4500 miles or so and I use Mobil 1 oil. Manufacturers love to point out how little it costs to maintain their vehicles but changing your oil every 10k will ensure you’ll be replacing your vehicle sooner than later and that benefits the dealership.

Stopped buying the dealer oil and switched to Mobil one esp x2, stopped asking for more oil between 5k changes.

As an avid amsoil user I am bought into the brand. Every product I have has made my equipment run better. I run a small farm and have amsoil in every fluid in all of my vehicles. If you are in the preferred deal it really isn't that much more expensive than regular oil.

My L5P doesn't tick with amsoil. My 5.3 you can't hear the lifters with amsoil. I have a 5.3 that has 300k on it and never had a motor problem with it and it has been pure amsoil since 35k miles.

I’m from saudi and the owner’s manual recommends 0w20 or 5w30, never mentioned 0w16 despite that the engine is the same (A25A-FKS). Im using mobil 5w30 btw

I run 10-40 mobil1 in my VR now. had 5-30 and it ran just about the same, didnt notice any difference really.

Fellas, Don't bother running Mobil1 for extended period of time. I have done 2 consecutive oil tests on Mobil1 0W-40. One with 6200 miles and the other was at 4700 miles. Used OEM filters in both cases. Results: With the 6200 mile drain interval, the iron and the lead levels were up there through the roof! With the 4700 mile drain interval, the iron was within average and the lead was couple of points above the average.
