Confused: What oil to use in tensioner?

Yep, the gear oil isnt going to stop leaks. the molecules of oil or water are the same size, however, the viscosity , as Glen said, will just slow the leak down, but it will still leak just the same. (just take longer)

I cured the leaking Tensioner on the SE when I last did the TB. Didn't use a gasket between tensioner and block (didn't have one and I didn't want to wait. Just sued some RTV Sealant - - has worked fine for the last 4 years.
Come to think of it I didn't have a WP gasket either - RTV has worked equally well.

I'll squirt in whatever is in the oil can. Handy with the pump-fill action. Usually 10w40 or 20w50 in there.
As you can see in the chart, gear oil is not radically thicker than engine oil despite the differences in the numbers. Use whatever you like, really. Thicker oil will ooze out more slowly, but it's not going to cause it to seal up.
Am I the only guy to re-build the tensioner without removing it from the block? That's another way to avoid leaks.

Glenn I know you know that there is a gasket that seals the tensioner to the block, it should be replaced when the tensioner is worked on.
It will usually be in bad condition as there are holes behind it that can fill with various liquids.
Also be careful with the puimp squirt can you can very easily blow off the inner sealing clamp on the rubber boot , a visene bottle works very well, try it

Greg, I cant say that to use the STP will result in better/ worse performance, but I know that when the tensioner is filled with STP it results in less comebacks for a leaking tensioner .
YMMV
I have not noticed any other problems with the Oil

Save time, money and risk of a leak and leave it alone.
I know that it's one more thing to add to a T-belt job. I don't replace anything that doesn't show wear. If the bearings are tight and smooth, it stays. This approach takes less money and less time and there is no infant mortality of the replacement parts. No, I've never been bitten by it either.

Amen to that! 
"Should be?" Why? If it's sealed it's sealed.
