Will i notice a discernible difference using the former over the latter in my Lyriks?

I’ve got Automatic gear oil in mine and its really nice.

thats just thick oil isn’t it?

Do they have foam rings or just oil seals?

if its 15 wt I’m guessings its for your lower leg lube in which case I can’t see it making the slightest differene what it is?!

think the title suggests its for the lowers also 😉

I used to use it, now use fully synth engine oil. A lot cheaper, no noticeable change in performance or oil condition.

Sometimes I put a small amount of Fox Float Fluid (the really thick 85wt stuff) on the seals and inside the air chamber. This does make a small difference you can feel in the garage, can’t say I’ve noticed it when riding though.

I use engine oil in my Rockshox ,it works fine
