Dear M: I hope that was your PARENTS 50th (gg). Seriously though, getting on to gasoline. I learned something this spring that has been useful. I drove to Las Vegas, and then Las Cruces for some offroading. I drive a Wrangler (tj) for my offroading trips and its like pushing a brick down the highway. At speeds over 60mph the gas mileage is just AWEFUL, especially when I have my offroad tires on. Well, out west you drive 70 and 75 and my gas mileage dropped to 11mpg. While in Las Cruces I learned of a gas additive made by LUCAS. Costs about $7 a bottle (32oz) and you put 3 oz in per 10 gal. of gas. I never much believed in additives but in desperation bought a bottle. First tank I put in 6 oz and got 12mpg. By the time I got back to Fla. I was getting, 17 MILES PER GALLON. I was so excited I did some research and learned that 50% of gas sold in America is deficient, this corrects it. Anyhow, got several of my club members to try it and sure enough WE ALL are getting fantastic gas mileage (for a wrangler). So now, I put it in every other tank and have maintained that 17mpg now ever since late May. jdn

depends on what mfg of engine requires for octane. if reg octane is 87 and super 93 and mfg requires 89/90 octane the mix of both is ok as filling half and half brings octane level to 90. As long as you have no knocking in engine i expect what gasoline you burn you are ok. if not i believe you are doing damage to the engine that will eventually cost you an early engine failure which we much more expensive that the extra pennies you would pay at the pump.

the new engines adjust for octane and burn accordingly. you lose a little power, mileage but the engine will run without damage as its electronics adjust to the octane it is burning.

lower grade of gasoline will also mean a lower additive package in the gasoline.
