- Many gas line drier products are just plain methanol, which can attact
- rubber and even metal. The better products (though less frequently found)
- are isopropyl alcohol. This stuff is more benign, and and carry more water
- as well. It also is a good fuel injector cleaner

- Methanol (and I think isopropyl alcohol too) is a high octane fuel, and so will
- reduce pinging. Although water is not a fuel, if mixed with fuel, it will
- also help prevent pinging. This has to be done carefully--you can't just
- dump water into your gas tank.
