Does the more expensive gas really help?

Question

Does buying the more expensive gas;unleaded plus, unleaded super,etc.. really help?? or is just unleaded regular the same as both?? because i heard the more expensive the gas the more fuel effiecint your car becomes, is this true?

Answer 1

More expensive gasoline will only help those with vehicles to take advantage of the more expensive fuels.

The different octane ratings, is actually a rating on how resistant the fuel is to ignition. So 91 octane is MORE resistant to ignition than 87 octane.

The reason you want fuels to be more resistant to igntion is to allow for higher compression. If you drive a sports car, a luxury sedan, and even some mini vans, the higher octane will provide more power for your vehicle.

You can use the expensive stuff in a regular vehicle, but you won't benefit at all. So check to determine if you car needs the higher octane.

If the car manufacturer says "recommended", typically it means the manufacture has placed a "knock" sensor on the engine to allow an owner to use the cheaper gasoline.

If the car manufacturer says "required", it means you must put the minimum octane required by the manufacturer because the high compression engine will cause the cheaper gasolines to pre-ignite. Preigniton will typically occur in areas of the cylinder other than where the spark plug is located. This will cause multiple flame fronts to occur. When the flame fronts collide, you will generate shock waves inside the cylinder. The shock waves will cause excessive engine wear and damage. You can typically know if you are generating these shock waves, as you will hear it as "knocking" coming from the engine compartment.

For cars that can take advantage of the higher octane, the typical result is more power, not fuel efficiency.

Answer 2

decrease value gas stations get there gas from a "call type" resource. besides the incontrovertible fact that, decrease value stations are utilising older gas which replaced into no longer being utilized by the call manufacturers. call type places desire to sell the maximum modern stuff possible. with a view to try this, something older is sent off to diminish value gas bars at a discounted fee..hence it is bought at a discounted value. Like very just about the rest, gas has a shelf existence. The older it is the fewer powerful it is going to likely be. I constantly stick to call type places as a results of fact they have have been given the "brisker" grant.

Answer 3

Read your manual most cars run on regular unleaded octane 87 or 89.

Answer 4

No, if your car is designed to use regular, use regular. If the car was designed for better gas, yes you might see some problems if you use regular instead, but not always.
