So I keep seeing these mods to improve mpg that cost so much money, the money saved by gaining mpg is far outweighed by the cost of the product or part. So I'm wondering if anyone knows of free or cheap mpg mods that will make sense economically.
If I remember right, higher intake temp is condusive for higher mpg, so do I work on higher intake temp? Or is that entirely the wrong direction?
Tailgate up or down?
Chin spoiler on or off?(its off now)
Different lube in the transfer-case and diffs?
Synthetic engine oil?
K&N air filter?
ect ect ect....
I got a truck with a 5.2 for economy and i'll be darned if I don't get better mpg than a 5.9 (Last I checked I barely got 10). I've been trying to drive more efficiently, so I can get better mpg, but if I can do some modifications to get the same mpg driving normal and avoid the emasculating experience of driving like a hyper-miling hippie, I'd be glad for the input.
Don't get me wrong, I love my truck, I love driving it, and I'm ok spending a little extra on gas, but I hate wasting my money, so, if you've got any ideas, hit me.
