Let's go over this again. The Material Safety Data Sheet or MSDS say that octane booster is 99% kerosene. 16 ounces of it will turn 25 gallons of 87 octane gas into 93 octane gas
Here is the product;
Synergyn 120+ Octane Boost adds 6 octane numbers
Now I stated that diesel and kerosene are similar, not exactly the same but close enough. Here is another link on refining, this is page 2 it's a good read. Both come from the same spectrum of crude oil
HowStuffWorks "Carbon Chains in Petroleum Products"
Now I stated that since they are close together and one is used as octane booster the othe one will work. I never said fill you car with one or the other, I only said if used in the proportion suggested it will make regular into high octane gas
If 16oz kerosene makes 25 gallo d of 87 into 93, similar quantity of diesel should do a similar effect. I don't have te equipment to test, but anywhere from 92-94 octan
128 ounces in a gallon. 16 oz is 1/8 th of a gallon. So 1/8 to 25 gallons is 1:200 ratio, or .5%! Less than I thought, so if you add more then you are running fuel that does not burn completely untill well into the power stroke, acts as if the timing is way retarded.
