Changing the gas my car uses?

I am currentley driving an '94 Ford ThunderBird which reguires regular unleaded gasoline. My guestion is, is it ok to pur in Unleaded Plus gasoline? My girlfriend's step-farther said that it adds several horsepower to your engine and he does it all the time. Is this correct? Also, I will be getting a Dodge Ram 1500 (v8 Magnum) within weeks. Can I use the %26quot;plus%26quot; fuel on this aswell ro stick with regular unleaded?Changing the gas my car uses?Use the owner's manual as a bible. You won't notice any performance change but you will notice the cost if you use a higher grade than the engine requires. Octaine is figured by the people who built the engine; follow their recommendation.

Won't hurt it at all. However, any horsepower gain will not be noticeable.



Kind of a waste of money really, unless you car requires it.

OK, First of all, it will NOT ADD HP! Period. It will run fine.

Let me explain:





The octane rating of gasoline tells you how much the fuel can be compressed before it spontaneously ignites. When gas ignites by compression rather than because of the spark from the spark plug, it causes knocking in the engine. Knocking can damage an engine, so it is not something you want to have happening. Lower-octane gas (like %26quot;regular%26quot; 87-octane gasoline) can handle the least amount of compression before igniting.



The compression ratio of your engine determines the octane rating of the gas you must use in the car. One way to increase the horsepower of an engine of a given displacement is to increase its compression ratio. So a %26quot;high-performance engine%26quot; has a higher compression ratio and requires higher-octane fuel. The advantage of a high compression ratio is that it gives your engine a higher horsepower rating for a given engine weight -- that is what makes the engine %26quot;high performance.%26quot; The disadvantage is that the gasoline for your engine costs more.
the plus fuel only helps in high compression motors you will see no benefit..

that dodge will drink so much you will be wanting to use the cheapest fuel you can find for that pig..

buy a ford or Chevy instead
You can put in the plus if you want to, but you will only be spending your money, If your car or anyone else don't call for anything but regular then that is all you need. Putting in plus gas will not add any horsepower to an engine and in some cases could damage an engine, but that is not likely.
your girlfriend's step father is very wrong, but that is a common misrepresentation. The trick is to use the least amount of octane that doesn't make your car %26quot;knock%26quot;. Otherwise you are blowing your money. There is only 4-5 vehicles that require the higher octane (Porshe, Ferrari and cars like that). Your HP is set by your motor and its accessories, not the gas. The same amount of gas enters your cylinders no matter what type it is.
Follow your owners manual. In your case- the T-Bird- 87 ought to be fine. The general consensus is that if your car needs 89 or 91, use it, otherwise, use 87 octane.
