10w-40 AMSOIL for metric bikes. Bike runs and shifts like new with 30k on the clock
Idemitsu is responsible for the oil that powered the Mazda 787b; they know the rotary like no other. I exclusively use their synthetic 20w50 and premix.
Regarding brands, if you want to stick with factory oil without dealer price, Idemitsu is the brand to get. I emailed Mazda corporate and they said Idemitsu is the OEM for their oil.
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
For me amsoil signature series 0w20 a lot better than ravenol ehs 0w20.
I'm regularly using amsoil ss on my Honda L15z1 engine almost 7 years.
I just switched over to amsoil and my mpg went down marginally. Also using the PPE larger oil filter 10 micron filter.
I am not hating on Amsoil. I am running their engine oil and ****ing hate it. burned off another quarter of a quart in the last day of driving... ive never had this kind of consumption before and there are no leaks...
