Q: So my father was saying he was getting this chip for his truck. Well its suppose to make your truck or car get better gas mileage and I was just wondering if it was worth to get or if it actually works?
A: Don't do it. Your engine already run on hair edge of top efficiency. If your engine ran any more leaner, they would knock (engine detonation) and destroy the engine from the inside out. ====== There are few thing you can do to save (or maximize) gas MPG. First get a tune-up. (1) spark plugs (2) spark plug wires (3) distributors, coil, rotors (if you have them). (4) new air filter (5) PCV (6) correct tire pressure (7) clear the trunk of useless heavy items (8) spray clean MAF sensor. =========== =========== =========== Forget all those "SAVE GAS" scams. This was on NBC morning TV show. The difference is as much as 38% (their claim). There are very simple rules to save gas: (1) drive slow - not too much past 55 (2) accelerate slowly (3) don't brake unnecessarily (4) use cruise control - whenever it is safe to do so. Don't coast - it is NOT safe (to coast in Nuetral) and it does NOT save gas. It only saves gas, if you are planning to slow down (exiting, tolls, traffic). Coasting then accelerating again is LESS efficient than just cruising. The above really works. Using those simple rules I was able to drive from Boston to NYC (210.5 miles) on just 5.112 gallon (94 Civic). That's 41 MPG (94 Civic 187K miles). Actually I was speeding at 72 MPH so I could do even better at 55. WOW !! Good Luck.....
