Folks -
Hypothetical situation:
A bit older beater, been cleaned up real nice, crankcase real clean, no oil comsumption, engine in perfect tune, good compression numbers, ALL new hoses, rubber, belts, bushings, etc. Car generally nice, in an old perfect fit shoe, kinda ugly skin way.....got the picture in your mind?
One problem: Car still has combustion chamber (cc) deposits. The car pings like a marble factory on regular 87 (R-MON), medium ping on midrgrade, and generally OK on 92+. New car did not ping of regular and deposits observed with bore scope. Some liquid in the gas tank cleaners will tried before more radical approaches are attempted. The products are selected.
OK - Does (in general) the grade of fuel used with the in tank products make a difference?
Please resist the urge to push your favorite product (ok to mention how one or the other products works with this or that grade of fuel).
My null hypothesis: Regular fuel (ping and all) has a better cleaning effect when combined with in-tank cleaners. No science to back my claim - just crap flying out of the exhaust pipe.
