I was helping with oil change
He bought awsoil is it any good I never heard of the brand
He said it better than mobile1
He got it full synthetic and always change at 100000miles although recommended is 12000miles
He has a mazda
He been using that since he got the car ?
No such thing as Awsoil. But there is Amsoil. It's high quality oil, but very overpriced and a waste of money.
We have repeated it over and over on this forum hundreds of times. Use oil that meets the specifications listed in your owner's manual. That's ALL you need.
It his money not mine I just helped him lol
And if it's overpriced is it good ?
Forgot to mentioned it is compatible with car and engine
change the oil every 5-6,000 miles , no matter which oil you use
" And if it's overpriced is it good ?"
It will not provide any measurable improvement to the vehicle over Mobil1 , or any other oil that meets the specification required by the manufacturer.
