How many miles total?
Mine had had 250 miles when I brought it in...for the same thing
Losing a quart every 50 miles, no smoke, no oil burning smell, passed leak down, but was a little low on compression check.
I will almost guaranty, you have a piston land failure!(what I had)
Expect a week to get an answer from Polaris (hope your under warranty)
I received a new short block, some got whole new motors

..others got a rebuild :rm_thumbdown:
I was down about month..
Polaris hinted improper break in (which is not true)
New break in instructions were giving to me, by my dealer..(2) tanks at half throttle..multiple heat cycles, etc..should be able to have it broke in, in about 200 more miles..lol
Good luck!
