Hey guys, I'm going to change the chaincase oil in my sled tomorrow night. I have an 01 MXZ and was just wondering what i should use. I never got an owners manual when I bought the sled. So far I have heard I can use ATF or 5W30 Synthetic oil, and or 75W90? What should I use?

i use synthetic 75w90 and the gears and chain look like new.

ski-doo. amsoil or klotz all make a synthetic chaincase lube that would work fine for ya. i believe your sled to hold about 8 ounces to get you close since you don't have a owners manual, good luck

I started using atf in my two sleds becuase I dont think those parts really get that much use abuse compared to the transmission in a car, so I switched and besides is the OE oil really that good, or is it just another money maker for them.

I use klotz only and it does hold 8 ounces.

Actually they hold 8.5 ozs. to the full mark on the dip stick. My old sled I always used ATF, over 38,000 miles and not one blown bearing so I would have to say it is all you need. My new sled I run Doo Syn. chaincase oil

I'd use anything but Doo oil. Not because it's bad or anything, just WAAAAAAAAAAAAAAAAY overpriced. Personally I use Amsiol. :div20:

Your sled had 38,000 miles on it. What was it for a sled?

What weight is the brand name chaincase lube????? It never says on it and I think you could use anything that is the same weight. :banana:

I use Mobil 1 Delvac Synthetic Diesel 10W40 Oil.

1992 Mach I with 617cc motor. actual mileage on odometer reads 38,627 still has more life in it and will be on the trails again this winter some time after I rebuild the motor for the 3rd time

You just doing the top end each time? ie not the crank or anything?

If so thats great!!!!!

mobil 1 synethic gear oil 75-90

chaincase oil viscosity should be @ 10w I would never put 75w90 in any sled it's a chaincase not a gear case. even 4X4 trucks now days use ATF in the transfer cases........75w90 NO NO NO NO NO NO I use Amsoil
