Increasing the mpg of my 4.0L '98 Jeep Wrangler?
I am interested in ways to increase the mpg of my Wrangler. I have owned it for a year and a half and decided to crunch some numbers today which ended up shocking me... In 18 months I have put 35,000 miles on it, at an average of 13 mpg that means I have burned approx. 2,700 gallons of gas which at an average cost of $2.70 per gallon is nearly $7,300 in gas.. WOW!!!
I have already installed a Banks cold-air intake on it but hadn't noticed any mpg increase partially due to the fact that I enjoyed smashing the pedal down to hear that intake growl. Realizing just how much money and gas I have used though should make it pretty easy to break that habit. I have been researching the benefits of a full exhaust system upgrade including torque tube headers, 2 1/2" tubing all the way to the back and a high flow catalytic converter and muffler along the way. Just recently I also read that converting the engine cooling fan to electric as opposed to belt driven can provide noticeable increases as well since the electric fan will only turn on when needed.
Will these proposed upgrades net me noticeable gains in the gas mileage department with the 4.0L engine if I can keep my foot out of the pedal? If so about how much would you guess?
Please no comments telling me to sell the Wrangler and buy a hybrid.. I do my part to be green, using cloth grocery bags, recycling, shutting off the water whenever possible, etc. My Jeep is my guilty pleasure and I have never been in a more comfortable or beautiful vehicle before.. it is my most prized material posession.
