Hi As for the idea about the Regular and the Premium gas there are no difference I have a 1996 LS400 with 111.590 miles and have only used Regular gas in that car I really don't see any difference with 5 octane I don't hear any ping plus the miles I get are in the City 18.6 and on the highway is 25.8 miles per gallon on the highway I use the cruise control all the time, as for repairs I have never had any thing done with the motor.
