- Here is some guidelines to start with. Perhaps John De Armond
- (jgd@dixie.comz) can varify/add to this. He done some testing on the
- effects on fuel injectors, etc..
-
- For gas-line dryers:
- OK = Isopropyl alcohol.
- Avoid = ethanol and methanol.
-
- The non-dryer type stuff for cleaning fuel systems:
- OK = Naphtha, Toluene, Xylene, various ethers,
- Should be OK = Aromatic solvents, petroleum distilates.
- (This stuff could be many things but the families
- should be OK.)
- Avoid? = Acetone, MEK Methyl Ethyl Ketone. (I'm not sure on this.)
-
- Perhaps add this to the FAQ list.

- No. It stops pinging by slightly raising the octane rating with one
- of it's additives or cleaning deposits off of various parts.
