Chain Case Oil?

[Pastor]

What do you like to run in the chain case and why.

I wonder how some full synthetic 5/30 would work?

I have heard some are concerned about the 90 wt creating to much drag.

I would like to hear your opinions.

Thanks

I run 75-90wt synthetic, seems to work well. Synthetics are usually a better choice for cold climates.

I was told in a turbo sled to only run synthetic gear oil as in the colder temps you will have problems.

LET THE DEBATE BEGIN​

This has been beat to death many times over in the Polaris section.

Most cars / trucks use transmission fluid in gearbox.

So ... use transmission fluid.

Been using for several years on most brands with less wear / shavings and absolutely no problems.

If you choose to use transmission fluid does it matter which kind?

 

[philsummers21]

When he says transmission fluid im guessing he meens manual Transmission NOT atf. I use Trans 50 Synthetic Transmission fluid.

I have run Bel-ray Gear Saver works well and never had a problem

In my Summit I used Mobil 1 ATF and it worked fine. I never saw any sign of wear on the chain or sprockets and it came out as clean as it went in.

On my Nytro, I use Shell synthetic chain case oil.

I would not use ATF it is a fluid not a lubricant. Meaning it is more like a a hydraulic oil than a lubricating oil. A good synthetic gear oil is by far the best way to go. They have better protection and flow better at lower temps.

Years ago when Ice racing, we tried the atf. Only once because we lost a chain case after 100miles of a 500 mile race. On the first pit stop we knew it was going to happen. Even though full, the chain case was hotter, and the fluid was already burnt.

From Websters

Fluid 1 a : having particles that easily move and change their relative position without a separation of the mass and that easily yield to pressure : capable of flowing

Lubricant-1 : a substance (as grease) capable of reducing friction, heat, and wear when introduced as a film between solid surfaces
2 : something that lessens or prevents friction or difficulty
