Guys I just bought a gallon of Quaker State marine injection oil for use in my 400 Polaris. It does have the TC-W3 rating and I think it will be fine but since it is a marine{outboard motor} oil I thought I would ask. Is it safe to use marine oil?

 

TC-W3 is the latest rating for watercraft. Atv's and dirt bikes don't have a rating and never did. TC-W2 is the same as TC-W3 only a newer rating.

 

i have been using quakerstate syn. oil for 3 years in my 400 EXP and it works fine. my plug has 2600 miles on it and it has not been changed. you can get quakerstate oil at walmart for $18.00 a gallon.
