|There are those who claim (and I am not one of them) that installing an engine grounding kit may your increase gas mileage. It didn't help mine, but I met someone who said installing a grounding kit helped his gas mileage, and he seemed to be a pretty normal guy (i.e., not a flake).|
I just did a long term test on the effect of a grounding kit on the mileage that my VR6 gets. Same type of driving before and after - the only difference was the extra ground wiring. The test included over 28500 miles and nearly 14 months and at the end I learned one thing ...
... the grounding kit had ABSOLUTELY NO STATISTICALLY- SIGNIFICANT EFFECT on fuel economy. Here are the numbers:
NO GROUNDING KIT
Miles - 13759
Fuel Economy - 27.145 MPG
WITH GROUNDING KIT
Miles - 14807
Fuel Economy - 27.112 MPG
That's a difference of only 0.12%, which over the time/mileage span tested, is NO EFFECT by any statistical standard.
I'll be posting a full write-up on the test as soon as I fin the time.
