I'm planning to change the oil and inspect the seals sometime before my ski lift opens up, and was gathering the tools I need. I'm going to have to purchase the sockets, but other then that I should be OK.

What I don't want to buy is the fox suspension fluid, as I just feel like i'm getting majorly ripped off.

I live next to a few well equipped and big motorcross/motorbike stores, and Andorra is full of them, is there any chance I can buy motorbike oil?

Either different weights and mix or whatever, then I can buy a large amount. Fox fluid is 7wt, if it matters.

thanks

I assume your talking about the lubrication oil and not the damping oil?
If it's just the lube oil, almost any suspension oil will work. I buy 5wt at the moto shop by the quart. Get a big syringe so you can measure it and squirt it in through the bottom instead of pulling the top caps.

Golden Spectra. Best fork oil. I use mostly 7wt with a touch of 5wt in my 888.

I ran into a similar problem, locating Fox oil for a reasonable price (here in Finland). Fortunately, most shops here stock Motorex fork oil so I mixed some 7.5wt with a splash of 5wt (4:1 ratio).

I'm no Texan, but I recon' it's pretty close to the factory oil's viscosity (cSt).

This chart may help you select some suitable oils:

In the 40, the damping oil and the lube oil are seperate. The damping oil is inside the cartridge.
It really doesn't matter what weight of lube oil you use. Thinner is probably better.

won't thinner screw with the seals?

any oil of that weight will work, fuchs probably makes some of the best lubricants anywhere, when i changed to that in my 888 from stock which i beleive is actually golden spectro or one of the other big companies makes it for marz, you could tell there was a difference pretty easily, that is why so many companies use it

Paint thinner?

Mixing lighter and heavier synthetic fork oils should have no impact on the seals unless the oil has some seal swelling additive. Most quality fork oils should not contain any such voodoo.
