quaker state motor oil
Best bet is Polaris synthetic.
how do u bypass the oil injection on a polaris 400 2x4 scrambler
Penis oil
2 quarts with filter change
Open and read your owner's manual. Do not have an owner's manual then you need to get one.
driver side in the middle their will be a 3/4 inwrench nut to drain i out.
As you sit on the ATV the oil filter is on the left side behind the oil storage tank inside the front wheel fender.
4cycle
It depends on a trailblazer 250 they have no crankcase oil but on a 400 water cooled scrambler they do so yes you need to change the oil with regular motor oil
If you do not want to use Polaris trans oil ,they recommend 30 w engine oil
2 cycle engine oil. I prefer to use a synthetic designed for ATV's and Snowmobiles. It doesn't smoke as much and stinks much less.
it is simple, it is right below the head of of the atv. On a polaris scrambler it is right in front of the left rear fender
