I'm sure FP60 will be fine in the fuel. BTW, have you noticed how BOTH of these fluids sure are slippery-feeling?
I have this question put to the LCD site, so, if they write back, I'll tell you what they say. My GUESS is that it will be OK....because I THINK auto trans clutch-packs are similar enough to wet clutches, but, I don't know that for a fact.
