Bad performance ,pinging ,engine detonation,over heating, just too name a few.
Big boom-boom.
Not as long as the premium fuel is also unleaded.
That car has a knock sensor, so you won't destroy it. It will, however, run terrible because the timing's so retarded by the knock sensor.
The best gas mileage from unleaded gasoline or premium gasoline depends on the car. Old cars get better mileage from unleaded.
On a 1998 Lincoln Town Car : It depends on which engine you have : The 4.6 liter Single Over Head Cam V8 engine takes ( " regular " unleaded gasoline , 87 octane ) -------------------------------------------------------------------- If you have the 4.6 liter Dual Over Head Cam V8 engine ( some do ) it takes " premium " unleaded gasoline , 91 octane or higher ( there will be a " Premium Fuel Recommended " label behind your gas filler door
Nothing happens, except your wallet will be lighter.
Yes In a modern car changing from regular to premium is no problem It may have been costing you power and fuel mileage to run regular, but if your car does not need premium it is a waste of money. On older cars running regular may damage the engine, but we are talking cars built in the 1980s or older.
Bad idea. Most cars that are Premium Only are designed to take about 92 octane fuel at the lowest. The car will, in fact, run with super unleaded gas but it will create damage to your engine in the long-run. And if low octane gas is used frequently, it can greatly reduce the life of your car.
unleaded...besides that don't waste your money on premium gas, the car's not worth it.
If you accidentally put regular unleaded gas instead of premium in a vehicle designed for premium fuel, the car may experience a decrease in performance, such as reduced power and efficiency. In some cases, you might notice engine knocking or pinging due to premature ignition of the fuel. However, if it's a one-time mistake, most modern engines can handle the lower octane without significant damage. It's best to refill with premium gas at your next opportunity.
Yes. You may not get the same performance (horsepower) as you would with premium gas, but modern cars can run fine on any grade of unleaded gas.
every car that was designed to run on unleaded fuel can be ran on reg. unleaded fuel,it just will not make as much power and or run as smooth as with premium fuel
