About 7 years ago, I used to mix LC20
with VSOT, but I do not remember the ratio.
Had it in a gallon jug & used to sit around
and shake it alot. Used with DuraBlend 5w30 in
a 2004 Taco 4x4....ran smooth
When I first heard about the acetone idea added to the gas, If I recall 1 oz. per 10 gallons or something.....I was too scared to add the acetone directly to the tank, so I mixed it with 2 oz. of 2 cycle oil.
Didn't notice any difference in vehicle drivability/MPG....but the vehicle was a "new" vehicle.....~30-40k on the clock, 2007 model
So it coulda been it just didn't have anything that needed a clean up
Now I just use MMO or TCW-3 by itself....every year or so I may throw in a bottle of B-12 CHEMTOOL or somesuch...
lol, this reminds me of the thread where people were trying to "reverse engineer" Seafoam using Diesel Fuel, IPA, and something else
