Question: Why My Mpg Is So Low?

Does driving slower save gas?

Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go.

Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag..

Does lowering a car increase mpg?

Is low MPG good?

How low should I lower my car?

Most people don’t lower past 1.5-2 in. up front because they don’t have to cut their bump stops too much and they don’t have to get a camber kit to correct any excess camber. You’ll have to see what spring rate coupling balance you like for each amount of lowering achieved. I don’t recommend going more than 2 in.
