Does Using Premium Gasoline Really Save You Money?
On its own paying for premium gasoline does not make your car run
better or get greater gas mileage. Giving your car the fuel it requires to run
smoothly and efficiently, without damage to the engine, does make a difference
in your fuel mileage. Get your car serviced regularly. If your engine isn’t in
good repair, you can waste fuel.
The same holds true if your tires are underinflated, which can
reduce fuel efficiency.
You should use the recommended fuel degree of your manufacturer,
you should also use the right grade of motor oil.
