Engine oil OEM Mazda or AMSOIL

I did Amsoil once a year about 8 or 7k miles since I live 3 miles from work, decided and went with Penzoil every 5k miles on 2014 4runner. is cheaper and better than toyotas mobile oil

Amsoil, i have used this oil i

n my cars, trucks, motorcycles,  lawnmower and anything else that runs on gas, it's the best.

Amsoil signature series

10w-40 AMSOIL for metric bikes. Bike runs and shifts like new with 30k on the clock

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.

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

I just switched over to amsoil and my mpg went down marginally. Also using the PPE larger oil filter 10 micron filter.

AMSOIL - DO NOT USE THIS CRAP , No seriously this stuff is crap and it's not worth the risk. I put this in my R32 at 24,000 and the motor blew at 24,500 due to a depleted rod bearing.
