MPG Improvement?

[Tweeter400]

What are the best ways to improve MPG with the 5.3?

 

Fuel Filter?

Spark Plugs?

High Performance Air Filter?

Spark Plug Wires?

 

Do any of these make a big difference?

If anyone has any other suggestions, please let me know!

 

Thanks!!

The only thing that I have noticed for increase or should I say max fuel mileage is to drive as sensible as possible.  I work 20 miles from here and it is mostly highway driving. I filled my tank up and drove as sensible as possible.  I kept the speed at 55 and when I took off from lights and stop signs I eased up to speed. Nothing super slow but not the blistering fast speed I normally do. I noticed that I got 19mpg.  Now that is fine and dandy but in the real world and life is short I'm not going to do that all the time. Well at least not untill my wallet starts hurting for cash with the price of gas going up.

 

I also feel changing over to synthetics has helped. I read a lot of articles and talked to a lot of other people and the general consensis was synthetics help with everything, form gas mileage improvement to longer lasting equipment.

 

Of course keeping a clean air filter, and the engine tuned will always help. I didn't notice any difference with the change of the Mass Air Flow sensor, if I had to do it over again I would have left that out and just took the screen out of the stock MAS.

 

I've gotten some information off another forum and found a product called fuel power. It is suppose to help in the mpg area. I'm going to give it a try. There are a few individuals on that forum that really praise it and said it makes a difference.  I figure it can't hurt and is reasonable on the cost. I'm going by others recommendations off that forum. Once I find out I will post it here on new products. Keep your fingers crossed. :thumb:

Soft Tonneau cover (reduces wind resistance and is lighter than a hard cover)

 

Reduce vehicle weight (keep your bed empty and don't carry a bunch of tools in the cab all the time)

 

Reduce rolling resistance (small, narrow, properly inflated tires)

 

Place a thick wooden shim, hockey puck, or somesuch device between the gas pedal and the floor (or just exercise more self restraint than I can and don't floor it all the time).

 

 

These strategies WILL work to improve fuel efficiency.

 

 

Most engine mods that actually result in improved engine efficiency cost significantly more to acquire and install than the amount money saved over two years in reduced fuel consumption.

 

Spending money on the engine through the installation of an intake, headers, Cat-Back exhaust, etc. for the purpose of saving money through improved fuel efficiency doesn't work.
