If I use regular unleaded in this car one week and then next time it needs gas use Super Unleaded (alternating due to costs of gasoline) will it hurt the engine? The cost of gasoline is really expensive on this car. I purchased it as a first car for my daughter, we love the car, it runs great, but I am always having to pay for gasoline every week. Do you have any tips on how to save gasoline for this hungry beast? Thanks, Supercharge Girl....
Will it hurt this engine if regular unleaded is used instead of super unleaded? on 2001 Buick Regal

I would use the octane rating suggested for your engine. The engine does use a "knock sensor" it retards the ignition timing if it senses poor quality fuel. At least run the middle grade gas.
okay that is what I thought, but my husband is complaining about the cost of gas this car uses and he is telling my daughter to use regular unleaded gas, I have heard that it is not good if the owners manual says to use a higher octane.....I thought maybe we could alternate fuels but I dont want to risk it....thanks for your reply.
