Last night I lost the oil level check plug on my ZA at my friend's garage. We found the right size bolt, so that wasn't an issue, but I had spilled my ATF (Type F) everywhere. The only fluid we had nearby was generic ATF (not Type F).
This started a debate about whether or not you could use generic ATF in place of Type F ATF. I searched some threads on Moped Army, and indeed some people said it was fine, but no one explained why. So, some questions:
What is so different about Type F?
Why did Puch (and other companies) determine that this was suitable for mopeds?
What other oils and fluids have you successfully run in what engines? How did they affect performance?
One note: I once put this non-detergent motor oil we have since dubbed "Billy's Mystery Oil" in an E50, which, before long, started making all the sounds of hell and died out. We think it may be a bad clutch bushing, but it sounds pretty evil in there (haven't opened it yet). Thoughts on that?
