| Oh just to let the first post guy know. I didn't experience any problem with the catalytic converters as a result of this brief encounter with regular fuel. But then again I was very careful to drive it conservatively because I could tell it wasn't like the regular fuel. Whether or not extended use of regular will damage the cats used on these cars - I don't know and I don't want to find out. The first point I was trying to make was that the is no economy in using the regular gas because you lose the cost savings in less miles per gallon. I do like the cocktail (Mixture) idea that somebody else posted since these gas prices are going wild. If the car requires 91 then putting in 93 isn't giving you anymore. I guess you also do 2/3 of 93 octane and 1/3 of 87 octane - correct? Kind of hard to justify the extra hassle though, but gas prices being what they are - It is starting to look more attractive all the time. |
