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.
Yes you can. Super unleaded gas is just lower in lead so it will not leave as much residue in the system thus giving better gas mileage.
all cars today run on unleaded gasoline. however older cars(60's -70's) some ran on leaded or unleaded. even so , some cars today cannot run on regular gas which has a lower octane rating. some need to run on premium gas , which has a higher octane rating.....
The best gas mileage from unleaded gasoline or premium gasoline depends on the car. Old cars get better mileage from unleaded.
leaded gas has lead in it, unleaded does not Leaded petrol (or gas as you Americans quaintly call it) contained a chemical called Lead Tetraethyl to improve its performance. It was then discovered that the amount of lead given out by cars (or automobiles) was making city air dangerous to breathe and so its use has been forbidden. All petrol/gas is now unleaded and "green". Car engines have needed to be redesigned to allow them to burn the unleaded fuel.
Your average automobile will burn 87 octane unleaded gasoline. Some more sporty cars will burn 92 or 97 high octane unleaded fuels. All of which are a petroleum by product.
All are designed for regular unleaded All are designed for regular unleaded
Higher Octane levels in the higher grades of gas. All gas should be unleaded now.
According to the link below these four cars require premium unleaded fuel.
Most BMW Cars Take Unleaded Or For Some Special Ones Diesel.
