Synthetic fork oil?

[retcol]

My friend Eric had this to say:
I am currently running the WalMart brand Super Tech 5W-30 synthetic motor oil in Franky and Skunky.
Both of them work great! As it has a 5W (weight) base stock, it is just fine in these forks.
When it gets hotter from constant use, it gets a little thicker just like it is supposed to do.
As it is synthetic, it flows better and cleaner at all temperatures

Oil gets thinner when hot, not thicker.

Maybe a 15w or 20w would be the ticket if it is riding that much better with 30w now. 10w might be too light then.

It's very difficult to compare oil viscosities between different brands
I found this table that gives a good overview of the different fork oils on the market. http://www.qemsc.com.au/documents/suspensionoils.pdf
Needless to say it's better to compare the viscosities at the lower temperature level ( 40°C) as our forks will never reach 100°C!

Thanks john! The chart was very helpful. I don't understand why viscosities are not clearly listed on products - It would be much easier! After reviewing your chart I've decided to stick with the current Fork Oil I've got as the viscosity is similar to many 10 weight oils (43@ 40C). If I do change it out, I'll have to go up to a heavy 15 as Mr. Bill suggested!
