There are alot of snake oils out there that promise improvement. There are alot of gadgets out there also saying to improve mileage. Anyone really getting any results from anything??

 

Your foot. Ease up on the gas when taking off, and if its a manual, shift at 2k rpms.This works...I get about 2-4 mpgs better then when I drive the other way. Dont drive unless you have too.

 

Ya i average 300mi on a tank and when i drive like the people you usually are yelling at i got an extra 100mi out of a tank. That was about 23-24 mpg if i recall. It just sucks cause at least I had to concentrate to drive that way because its not my driving norm.

 

Either:
A= Drive less.
B= Drive a company vehicle all day as I do!
C= Who cares, its just money, ya can't take it w/ ya!

 

All of the fuel economy improvement ideas in this long read
{plus other mods to improve available torque}
have been read over and approved by:
...a retired engineer at both Chrysler and GE
...a retired engineer who once headed GM's Corvette group
...an active engineer at Toyota's Georgetown KY plant

These mods are real,
but you will notice that most just give small improvments
and you have to add up several mods to get to where you want to go:

I will be testing a K&N CAI on a 4.7 motor here pretty soon, commuting approx 170 miles a day and climbing approx 2500' from close to sea level... I will start a thread here when I do. look for it in about a week.

edit: oops, forgot to mention, I have another trick I plan to test... stay tuned...

 

you can put all kinds of money into high flow exhaust and air filters and engine system management chips and whatever else, but at what point do you break even on upgrades versus gas money saved??

If you drive alot it might be worth it, but if you just do around town stuff and the occasional trip to the mountain, my opinion is to just keep it well maintained, use good gas and dont drive with a heavy foot.

 

Most cost effective change is driver behavior...nearly free.

2nd most cost effective change is higher air pressure in tires.

3rd most cost effective change is ... surprise...an electric block heater either new or from a junkyard. The block heater keeps the engine warm and greatly reduces the warm up period when fuel economy is poor, as this graph from the Florida Dept of Transportation shows:

 

At least some people are being constructive. Searching some of the other posts in this forum are helpful. It helped me make a decision as not to spend money on some unneeded products. Thanks all.

 

My biggest thing is, if you want a truck, ur not going to get milage...it amazes me how many people ask how to get better than 14-16mpg in town...
