| I stopped at a station one time and they were out of Premium and Mid-grade. I put a tank of regular in and it was fine. Didn't seem to run as well and when it got down to half tank, I filled up with the super and it went back to normal. I have a 94 and I was told it has a "knock" sensor that retards the timing if the engine knocks. I didn't notice any knocking, but maybe it is my imagination, it just didn't seem to run as well. Since then I have only used Premium. For the few cents more, it just isn't worth possibly damaging something. I probably should have just put in enough to get me down the road, but being a "creature of habit" I just filled it up.
Bottom line - I really doubt if you would do any serious damage by using the regular gas, but it is probably best to use the recommended fuel. I feel fairly confident that the engineers have the engine "tweaked" for the premium fuel and that is where you get your best performance and economy. |
