First Tank Break In

I recently bought a new Polaris fuel injected sled and the dealer does not recommend putting oil in the gas tank for the first fill up.

Does anyone have any recommendations on this?

I to just bought a new polaris. Brought it home last week. My sled came with a tag around the filler cap instructing me to add 2 pints of oil to the first tank of gas for the break-in.

Twodeere, my sled had the same tag on it. The dealer had this to say when I questioned him.

"We don't put oil in the first tank because it's injected and it will plug up the injectors. The computer is set to give the engine more oil for the brake in period and will reset it self after a brake in period is done."

I had my 600 cfi top end rebuilt due to burndown last spring and my dealer put oil in my gas tank at 50 to 1 to make sure it was there this fall when I fire back up.

Good point, but I think I am going to trust that Polaris, at the factory puts the tag there for a reason and add the two pints to my first tank.

Different brand, but still has injectors....I pre-mixed the first tank on my 05 Doo 600 SDI, (and followed the break-in procedure in the owner's manual) and 7000+ miles later, the compression is still holding in the high 140's and I've had no engine troubles whatsoever (knock on wood). Most of the gurus on DooTalk recommend doing a top end job at 3000-4000 miles, but personally, I can't see fixing it if it ain't broke.

I would have to agree that the factory puts it there for a reason. And no offense to the good dealers out there, but....not all dealers are created equally as knowledgeable!

I always add oil on first tank. What if the oil pump isn't working at new. After first tank of gas check oil. If it didn't go down some, voila! you just saved your motor. Dealer can get a broken oil pump fixed way faster than a rebuild. Keeps you on the trail longer. I also add oil when running on warmer days and /or doing major pulls up the mountain. I view it as plugs are cheaper than a rebuild.

This is my opinion on this.There realy is not much that needs to be broke in.All of the new sleds have chrome bores and chrome rings with roller bearings.Things are going to seat within the first minutes.I can see that adding to much oil will cause more problems with carbon build up under the rings,on the pistons and head and gum up the exhaust valves.The dealers want you to run extra oil in it just in case there is air in the oil line because they don't want to do there job and prep the sled the way it should be.I am on my 8th new sled and never put extra oil in any of my sleds.I want to find out if there is a problem with it right away instead of masking the problem with extra oil.
