Well Most of the ideas i have read here are Great for saving Feul.... Some it up...
- Lower Tail Gate(or get a Teanu cover $$) Stops drag, will get ALOT more milage.. Especially when highway driving...
- More air in tires.. Try pushing a full wheel barrel of dirt with a slightly inflated tire.. Hare to get it rolling and keep it going.. More air pressure in the tires makes it easier for the tires to roll.
- CAI(Cold Air Intake). Had one on my Mazda(before the Bus drove over it) and it added ALOT more milage.. HOWEVER!!!! If you have a heavy foot, the reverse will happen and you will use MORE GAS!! You can spend anywhere from $50 CDN. for an Ebay CAI to $300+ CDN for a Named brand preformance intake.
- Exhaust. Will increase HP and get you better milage, but at a nice price. gonna spend some good money for this. I would go header befoe i would do exhaust. If you got the money to spend, do full exhaust header to tailpipe!
- Computer Chip. Looking at $300+ US for this chip. JET makes a nice performance chip that literally changed everything from shift points, to feul air mixture. Increases HP, feul efficency ect. Easy to install, but pricey.
- Spark Plugs/Wires. More spark, more fuel is burned. Better use of feul, more milage!
If you wanna do something cheap and Easy, do the plugs and wires and an Ebay CAI. Looking at about $100 CDN(includes Part Shipping) and a couple hours or labour and you will have 8-10+ more HP and better feul consumption.
BEST OF LUCK!
