You can use Marvel Mystery Oil, Super104 Octane booster, or 104 Octane
booster. Super 104 will raise the octane from 4 to 7 points, 104 Octane
booster will raise it 3 to 5 points, you will notice that the other
products do not say how much they will raise the octane. Your cheaper
boosters will be methanol alcohol based and the more expencive ones are
generally petrolium bases.
Do not use the cheap ones, alcohol plays pure hell with natural rubber
gaskets and o rings.
As always this is JMO.
