FORKOIL Question

[Blake]

Alright,

Today im replacing my steering stem bearings and fork seals.  ill be doing the bearings first of course, and was wondering if you guys could help me out.   i bought a quart of 15w40 oil for the visions standard 15weight, but if i wanted to up it to 20weight, could i use the 20w50 oil i use in the crankcase?(new of course)  also, how much of a difference is there between 15 and 20 weight?  i would like to stiffen up the front a little, but dont really want it to be a super stiff ride..

any suggestions?    if anyone gets this within the next few hours please let me know.  before i put the fork oil back in ill be back to check.  or just leave me a message on my aol messenger thing.  it'll be on.  you gotta love cable modems :)


Thanks a lot,

Blake

i use trans fluid, i don't think anyone dare put engine oil in the forks.

15 wt refers specificly to fork oil.

Ford stuff should work fine

Ii tried the recommended 15 wt fork oil first , every bump in the road almost  dislocated my sholders, then I used what we always used, ATF, I works Ok for me!  The Haynes book says 30wt motor oil for Great Brittan, but I'll pass on that too!

I use 15 wt motor oil (50/50 10w30 and 20w40) and it works fine. Nothing is too good for my Vision ;)

You mean I don't have to use the stuff thats $7.95 a quart ???

What about straight 30 wt motor oil  :o

I have used 10w30 motor oil many times over the years and have had good results. It is not as stable as 15w fork oil, since it will feel different at different temps. Also, the 15w of motor oil is different and will flow differently that the 15w of fork oil. Usually the fork oil is a bit heavier 15w fork is usually comp to 20w to 25w motor oil. I know I know, they should be the same, but if you try it you will know what I mean.

Hey guys, I did some real testing of the flow of different oils. With an orifice of sorts. 15w40 is not the same as a 15wt. for the forks. In fact a 5w30 is heavier than a 15wt. The best of all things I have found is 0w30 Mobil 1. Believe me on the following>>> It has the flow of the 15wt. when warm(70 degrees) without being "Thick" when cold(40 degrees). Basically it does not change much with varying temps. It's the best thing I have used in the forks of all my bikes that need 15wt.

AmsOil Light weight. Works wonders. Worth the few extra dollars. Pairs up great with a set of Progressive suspension springs.
