Quote (QuasarCorsica @ Feb. 22 2003,20:52)i used restore in my old 88 Corsica 2.0 5 speed with 180K, made a big difference in economy i bet i jumped 5 mpg's. that engine had probally never seen it before, it was mishandled before i got it.

unfourtanately, i don't believe that. I think the only way an  additive could help any vehicle gain 5 mpgs is if you "added" gas to a car that was out of gas. No offence but oil additives do hardly anything for fuel economy.

i dunno, but after i added it, driving 200 miles a week with the old girl, the fuel economy got better, engine was smoother too, might of been better gas, but the mpgs did go up.
