1/ are you sure? i have read that U.S. (i think in more than one place) U.S. uses the average of RON and MON =
(RON + MON) divided by two.

2/ Can someone verify the following formula for mixing. note that we are ASSUMING the 89 octane here is MON, and this MON is same as U.S. :

335 tank capacity: 13.9 gallons (ASSUME 13 GALLONS)
toluene octane is 114 (not sure if this is MON or mon/ron avereage).

12 gallons x 89(octane) = 1068.
1.3 gallons x 114(octane) = 148.2
1216.2 divided by 13 gallons

= 93.5 is the new octane

if the above assumptions and formula are correct, i only have to add 1.3 gallons of toluene per tanK:
if i use a little good lubricant (lucas, marvel) with each toluene pour: IS THIS SAFE FOR MY MOTOR & FUEL STYSEM on a regular basis?

If yes, how much of this lubricant do i have to add with each 1.3 gallon toluene pour?

.....BUT IF MY 89 OCTANE HERE IS RON, what is that the equivalant to in MON?

thanks
