Fork Oil question

I'm getting ready to do my fork seals on my bikes and I was wondering what is the best fork oil to use.
 
There are lots of good manufacturers out there..me personally use the Suzuki fork oil from my local dealership. And if you want a real hoot to ponder, and this is no joke, In the owners manual that i had sent to me from CA for my 77 gs 750 it says to use a 50/50 mix of 10w30 motor oil and automatic transmission fluid...NO KIDDING.. I damn near fell out when i read that!!!
 
The Suzuki manuals, depending on which model/manual, and which supplement you are looking at, recommend a range of oils from the 50-50 oil-ATF mixture (as noted by chuck), to fork oil, to motor oil. Honestly, I don’t think it matters much as long as the viscosity is correct. And speaking of viscosity, getting fork oil is almost the only good way to assure you are getting the proper weight so you may as well just get the fork oil.
 
wonder how stiff the forks would be with some 80 wgt gear oil!! LMAO add a few large nuts between the caps and the top spring just for extra stiffness on top of that!!! LOL......no kids, dont try this at home!!!

80w is similar to something in the range or 40w engine oil if I remember the chart right.
Go with 15w fork oil Belray is fine or 20w if you want a firmer ride.
I have a mix in mine which puts it somewhere below 20 and above 15 with a spacer and 3psi and I like the ride just fine.

One bottle of fork oil is good for two complete changes of your forks. And what is fork oil anyway, like $8 a litre?
 
Chuck, there is a 50/50 mixture of dexron III and 20 Wt non-detergent oil in my '82...

so you can stop laughing any time now!

Belray is as good as any fork oil out there and easy to find.

Dale..I just thought that was hillarious when i read it..Thought to myself..now thats some old school technology there!!!
 
I throw in a bit of PFTE (Slick 50) in the mix...the teflon does seem to make the forks have less stiction and a smoother feel.
 
Belray is what the local dyno shop carries so that is what I buy. Have used other brands in the past, half dozen or another.

Slick50?

In the forks probably no harm. :-k

The bushings are PTFE coated from the looks of them.
