Reducing Gas Prices

We can reduce gas prices, and in many cases reduce our expenses in other areas, by reducing the demand for petroleum products. How do we reduce demand? Easy. Reduce consumption. Here are some suggestions on how to do that:

1. Make sure your tires are properly inflated. Improperly inflated tires reduce gas mileage. Most tires should be inflated to 32-35 psi, but look on your tires for specific numbers.

2. Make sure your engine is properly tuned. An out of tune engine wastes gas and money. Have it checked.

3. When you stop at a stop light, stay stopped until the light is green. Don’t try to ease up a little at a time – this not only wastes gas, but wears out your brakes sooner than normal.

4. Accelerate slowly. Rapid acceleration (“jack rabbit starts”) wastes gas.

5. Use synthetic oil whenever you change or have your oil changed. Since it’s synthetic, you are not using a petroleum product therefore you are reducing demand. Most cars actually get better gas mileage with synthetic oil, so it’s a win win.

6. Whenever possible, use alternative fuels such as biodiesel or E85. They not only reduce petroleum consumption, but they are cheaper and better for the environment. Unfortunately, they are not widely available yet in most places, but start asking about them when you buy gas and fuel distributors will begin to get the message; if they think there is a market, they will supply that market.

7. Don’t rush out to buy a new car… but if you are in the market for one anyway, consider buying a more fuel efficient car or even a hybrid car. Hybrid cars are more expensive but you can get a federal tax credit which will offset much of the extra expense and if you do a lot of driving, the money you save on gas will offset the rest.

8. Carpool.

Answer 3

fuel system and injector cleaners are ok if it's done with some regularity, same thing with engine additives, if the car hasn't had that done regularly it may be such a thing that when you put these additives in it is breaking loose alot of miles worth of sludge and crud which can hold true for both fuel systems and engine oils I sure if it started doing it right after adding it it may well work its way out of it.

Answer 4

Don't use anything that the owners manual does not say. Your nissan may need injector and induction cleaning services performed by your nissan dealer. But only every 60,000 miles. Keep clean oil and clean airfilters will make a bigger difference. Floor it once a while!

Answer 5

A GM mechanic friend of mine suggests a bottle of injector cleaner every once in awhile, but also having the entire system power cleaned every 30k miles.

Answer 6

You don't need additives if you keep up on preventative maintenance
