Engine oil Mobil or AMSOIL

After almost 2 weeks of usage, grabe as in grabeeee. napakasmooooth! hahaha tuwang tuwa ako kada throttle kasi mararamdaman mo talaga yung pagkatahimik+ smoothness + responsive throttle nya kaya ang laki ng tinipid sa gas. Kumbaga yung hinahanap ko na smoothnes ng takbo is dito ko nafeel when I start using this kind of oil. From 39 km/l naging 41.3 km/l na sya.

Now, my wife's '16 FORESTER XT, 2.0 turbo, has 130,000 miles, Amsoil changes every 10,000 miles, and still burns NO oil.

I’m team mobil 1, 160k and going strong.

Mobil 1 5w30 and oem Subaru filter. I change mine pretty religiously at 3750 miles. I know it might be overkill but I’d rather be safe than sorry and if my engine blows up I will for sure know it wasn’t my fault for neglecting maintenance.

Been running amsoil in my Vitpilen 701. Same engine and it's been great. I run the 15w-50 metric stuff though.

I’ve run amsoil in all my bikes and still do. Same with all my cars and trucks. Never had issues

Extractor all the way. As for The amount left behind, it is inconsequential if you are maintaining a short oil change interval. I've seen a couple YouTube videos showing maybe 3 or 4 oz left behind.

Anything Dexos2, my fiancé worked at a chev dealer and I was getting their bulk 5w30 dexos2 at cost and my LSPI issues went away, mobil1 ESP went in last oil change at 250k km

Mobil 1. Used to be a valvoline guy but my motor blew up lol. Dont think brand had anything to do with it, just felt like shaking things up.

I've used amsoil 5w40 European formula ir worked great for when it was a street car, switched to royal purple 5w-40 due to a recommendation and immediately regretted it, tons of blow by I didn't have before. Dumped the royal purple CRAP as soon as possible, just a few miles on it.
