Don,
Many octane booster products increase octane by "points". However they are talking about tenths of a full point (1/10).
For example, one well known octane booster says they can increase octane by "up to 7 points", when they mean 7/10's of a point. 93 octane goes to 93.7 with one bottle in a fill up.
Klotz is not like that. It is 2.5 "FULL POINTS" with 16 oz in 20 gallons. If you put in more per gallon, you will get more octane increase, but not exceeding "10 FULL POINTS"
1 bottle + fill up using 93 octane = 95.5 octane
2 bottles + fill up using 93 octane = 98 octane
But you could not get over 103 octane.
