transmission oil for polaris 330/325/250 trail boss/ trail blazer?
I wanted to ask if anyone out there was running anything besides the polaris AGL fluid in the transmission.

Has anyone tried anything thicker, like full synthetic mobil/rotella 10w40 oil?

The reason I ask is that we took our 250s to the sand dunes (modified with HPD pipe and silencer, clutch kit), and the transmission gets really hot! Granted it is a lot of work to take my 210 lbs up and down the dunes, but this was in May (not the heat of the summer).

I have taken the transmission completely apart before to reseal it, so I know what the inside is composed of...basically a silent chain and a couple of huge bearings.

Does anyone see a problem with running a little thicker oil, and has anyone ever done it?

Price of AGL is really not an issue.

I've seen posts in here where someone said they used regular motor oil. 10w30 if I remember right, but don't quote me on that.

I've always just used the AGL oil as it doesn't take that much. We've ridden in over 100 and never had a problem. But I've never had them out in any dunes, so don't know how that temp would compare.

You have to realize these are chain cases not gear boxes.Stat with a chain case lube.I wouldnt put a motor oil in it.

Transmission Fluid
You can use AMSOIL 2000 chaincase lube. Or AGL thats the only two I would use. I use the AMSOIL 2000 chaincase lube.
