I'll probably end up using 2/3 oz SI-1 / 10 G as part of a fuel additive mix.
Might try....
.66 oz SI-1, 2.5oz acetone, 1oz xylene, 1oz #2 diesel fuel, and 1/2 oz of synthetic motor oil, per ten gallons of gasoline.
We got yer injector cleaner...yer combustion boosters...some oomph from the diesel....and some top lube...
....that should cover everything/
