hey guys i have been making a magic mix that i thought i would share with you guys and its been working out realy well. i have a high comp motor and high oct gas is not easy to come by in mass unless you go up to the race track in NH lol so this is what i use .6 gallons 93 octaine pump gas no ethanol if possable 1.8 oz opti 2 oil 1 oz lucas oil octaine booster 1 oz lucas uppercylender lube i mix the upper cylender lube in and the octain booster in with .5 gallons of 93 then add some more gass to get exactly .6 gallons then i add a 1.8 oz packet of opti 2 oil to it and shake the heck out of it, then pour it in my tank for a perfect fit. the mix turns out to be 40:1 aroung 96 octaine perfect for a high comp motor arouund 145-150 psi or 11:1 to 12:1 comp ratio... plug chops show a perfect chocolate color and acceleration has been snappy and smooth !!! what your mix and do u use upper cylender lube how has it worked out for you ? i noticed that with the cylender lube my motor runns a lot quiter and smoother and there is a little les vibe. but thats all and that is enough for me to want to keep seing it lol i believe it helps keep the wear down on the cylender wall from our giant 2mm thick rings and heps lube up all the bearings and internals better than without it .
