performance chips. Do they really increase MPG?
I've seen these ads regarding performance chips. Herer's one that staes a MPG increase-
I'm curious if they really do increase MPG and if so, how hard are they to install?
08 Honda Civic LX sedan, auto
01 Chevy Silverado truck
99 Ford Contour sedan (Well, that's the wife's).
And a 1907 Baldwin Steam Locomotive (Really)
I tend to convert to Mobil-1 around the 8K mark
I'm also a believer in "Tufoil"-been adding that in my vehicles for 20+ years (And yes, I'm experimented with Duralube, Slick50, Prolong and zmax, and what did I find? No improvement in MPG. I keep on coming back to Tufoil).
