Don't fill your tank unless needed (lots of weight there).

I replaced all of my ignition components and added a chip, all in the same day, and noticed a nice increase in mpg.

The broken car mod, currently gets Infinite miles to the kilometer.

This is me :(. But it's hard not to lean into it all the time. Seeing i do drive a 383 stroker daily... But i do get 16mpg with city driving and a little highway tossed in there!

I'm the same way in my 540.

[mikeedler]

air up your tires and run stocker skinny tires.

Nah, then you have more drag from the open top.

I noticed a 2-3 mpg decrease when I did it to my nice, rare E30 Touring that needed some cosmetic restoration.

I only left a small hole for me to fit in , all other open space was welded shut.

i think the best and inexpensive mod I did was putting in a performance chip.
I would get about 29.7mpg @ average of 65 mph.

the lead foot mod doesn't help

Carbon Fiber metatarsus mod... work great for reducing sprung weight on the accelerometer

Weight reduction don't need it remove it. Gut the trunk, interior, remove A/C, power steering delete, elcetric fan conversion.

Less right foot, more 5th gear.
