2001 Buick Regal Q&A
2001 Buick Regal Question: Will it hurt this engine if regular unleaded is used instead of super unleaded?
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.... - Visitor
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. - patrick mannion
