Mixing brands or using a non-recommended oil may cause
serious engine damage. We recommend the use of Polaris
Premium 4 synthetic Oil or another 0W-40 API certified SH oil.
Never substitute or mix oil brands.
Oil Check
The 450/500 oil dipstick and fill
tube (1) are located on the left side of
the ATV. The 700 dipstick/oil fill (2) is
located on the engine and is accessible
on the left side of the ATV.
NOTE: A rising oil level between
checks in cool weather driving
can indicate contaminants
such as gas or moisture
collecting in the crankcase. If
the oil level is over the
full/safe mark, change the oil
immediately.
1. Position the ATV on a level surface.
NOTE: Do not start the 700 engine
before the oil check.
