Is it ok to use Moblie 1 75w synthetic oil in the chain case? I have 6 sleds and I change it every year and it adds up to use the manufacturer oil.
thanks

If you're looking to save some $$$$$$$$$$$$$ just use AUTOMATIC Transmission fluid.

I've used it for years in ALL brands of sleds

M1 75W90 is fine...

Have used M1 75W90 in all my chaincases for past 10 years, no problems including one sled with almost 9K on chain and gears. No need to use OEM oil for this.

ATF is the way to go used it for decades before diamond.most every one I know with a chain case uses ATF

I have used synthetic no-name brand for years also , never had a problem. The ONLY exception was that stupid " diamond juice " which I must admit I bought only because all the superstition around those diamond drives. Nothing like $15 for 12 oz......
Might try the ATF this year.

Thanks to all for reply I am going to try the M1 75w. the ATF makes sense too as I used it for years in my motocross bike tranny before we all went to the heavy expensive 4 strokers!

I still say 75 is to heavy especially at -10 syn ATF is the way to go no foaming thin enough to creep in to all bearing Even in sub zero temps

If you do use ATF this year, let us know if all goes well......And if not. Since I have only one with the DD, I'm gonna stick with the pricey stuff for now.

Why would you want to use that heavy oil in the chain case?

Unless you have the diamond drive setup....all you have is a chain and a couple bearings to lubricate at lower temps than you would ever get with your bike. That's why many use the tranny fluid....keep it light....and keep it full. Anything will work....but in cold temps, light is good.
 
I used 50w syn tranny fluid in my 02 edge. Now I have a '11 shift 600. So I'm not sure what I'm gonna use cuz it has warranty till 2015.

I have used syn trany fluid and it works great. The 75w will be thick at low temps and could cause failure. My two cents worth with +25 yrs as a mechanic.

This seems to be as large of a debate as witch 2 stroke oil is the best:D
from my experience 75w90 synthetic gear oil has worked well for me, my rev has over 10000 miles, and no issues, still the original gears and chain. Just my $.02 as 27 years as a mechanic. It is all very simple, the idea is to keep 2 gears and a chain wet with oil. I have in a pinch, fixed a buddys 96 mach z chain case out on the trail, only thing we had for oil was injection oil with us, we finished the trip without event. on a later trip with him, I asked if he ever changed out the injection oil in the chain case for regular chain case oil, his answer was no, he ended up riding the remainder of the season with injection oil in the chain case, just over 2800 miles, no issues.

Some, in an effort to save money use Automatic Transmission fluid or gear lube in their snowmobile/atv chain cases and gear cases. Neither fluid is engineered for these applications. ATF is a hydraulic fluid formulated without the extreme pressure additives needed to provide enhanced wear protection. Automotive gear lube is designed to lubricate hypoid gears and is too thick for proper chain and gear lubrication in powersports application, impairing circulation and leading to decreased efficiency.

And my 2 cents would be Amsoil synthetic chaincase oil. 9-11oz. has never killed anyone. I always pull side case off when changing and then inspect gears, chain and tensioner. Also I wipe out the sludge with cover off. Little more work, but if you leave in the solids then the oil change is somewhat incomplete. The little magnet on dip stick catches very little.

I personally run Amsoil ATF so obviously I am not doing it to try to save money. I have put over 9000 miles on a chain case without replacing any bearings, chains, or gears and when i check machines that use a gear lube I tend to find more metal shavings laying in the case. I really cant say which is better but I can say in my mind I think ATF is better.

I disagree on your assessment on ATF, or at least syn ATF. Many car manufacturers use syn ATF in their manual transmissions now. So apparently, it is a good lubricant for gears. Plus it's used in 4x4 transfer cases as well, which also have chains running on sprockets, So it must be good for a chain drive lube too.
 
So if I don't use what Polaris recommends in chain cases, would it void my warranty if I choose to use something else, on a side note, what do these new sleds come with for fluid in the case?
