Hi
Im having a go at servicing my forks myself to save some dosh.
I have rev's on one bike and fox on other,

Fox recommend 7w oil for their lowers while sram recommend 15w oil in theirs,
I like to keep things simple so I went to the nearest motorbike shop and got 10w
Will this be ok to use for both lowers.
they didn't have any 7 or 15 anyhow;)

Yes.
SRAM are American and recomend thicker oil for their fatter riders ๐Ÿ˜‰
.
Seriously though, I use Silkolene 10wt in my Maguras and that works well. I have a set of old Pace fork which need something lighter so I mix the 10wt with 5wt and that seems fine too.
.
You may find, using 10wt, that the forks whcih had 7wt in before are more heavily damped and those which had 15wt in from the factory less damped. Try it and see how you like it. If it doesn't suit, change to something lighter/heavier as appropriate.

It doesn't matter what you use in the lowers of the RS Rev's because the oil there is just for lubrication and not damping as they are closed damper/semi-bath, I use good quality synthetic engine oil in the lowers of my Reba's because it's a better lubricant. Are the Fox forks open bath or closed damper (FIT)? If they are closed damper then again it doesn't really matter which oil you use but if they're open bath you need to use the correct weight suspension fluid as it is for damping as well as lubrication. The viscosity of Fox 7WT Fork Fluid is 31.82 cSt @40C so you want something close to this regardless of what weight the sticker on the bottle says, a very good oil is Red Line of which Medium is a close enough match ( http://www.opieoils.co.uk/p-60184-red-line-medium-suspension-fluid.aspx).

Andrewh.. ๐Ÿ™„
Lowers he said, not in the damper..
Yep, I use 10wt in the lowers on RS and Maguras, and Fox Float Fluid on the foam rings, although when I run out of that I'm getting some 80wt gear oil.

Have you tried Rockshox seals on the Maguras? Stops them weeping so much.. I took the lowers off mine at the weekend, and was surprised to find that they were clean inside for the first time ever! The two part seals with the separate oil seal won't fit, but the one part ones are fine with the old foam rings, or the new ones cut down.

What brand 10WT oil did you get and what is the cSt@40C based on the below table? If it is close to 31.82 cSt@40C then it'll be fine in the Talas (assuming you should be using Fox 7WT in it).
