What was your most succesful mod?

[ecocruze]

Would like to see who has had the most successful mods on an SUV or car but trucks are welcome are welcome as well. Would like to help pinpoint what will be the most influential to each vehicles efficiency first. Gives new members a better direction.

I will start this off with my least successful mod sadly. Penny pinching and switched to none LLR tires. Lost around 10% efficiency. I believe that correlates more so with my coasting distance.
Best mod by far was switch to copper plugs in my cruze. Was able to run down rpms much lower in top gear and upon discovering this increased my mpg by roughly 10% as well. So back where I started until i mod something else or get new LLR tires. Hope this gets people going. Would like to see where you were successful. I know there are points people have made 100 pages deep in probably not seeing. This site is one helluva information mine but sometimes you don't now the key word or don't have a hyperlink. Thanks happy ecomodding!

Definitely the most successful (and fun) mod was the the 3-button shift knob on my Insights. It was a must-have for the G1 Insight owner!

This, probably. Or at least, what those buttons let you do, which is control assist/regen, and start or stop the engine on-demand. Basically, a really smart kill switch.

Air dam. Closely follwed and maybe surpassed by power steering delete.

What kind of gains did you see from the airdam? I find it more intriguing when air dams are so successful on smaller cars. I know my Explorer could use one but that will come when I get a chance to pick up a junkyard front bumper. The Cruze I wouldn't expect much gain with the underbody panels and all besides clearance being too low for areas I drive already.

My most successful eco-mod to date is the lowering of my suspension... caused a very noticeable difference in coasting distance and on highway mileage... probably as much as 10% at 75-80mph...

I never did ABA testing on the airdam, since it is a common mod, known to work. What I noticed when it had to be replaced a few years ago, and once when it was hanging down after I hit it into a parking block, is that I seemed to lose two or three MPG. "Most successful" to me is not just about the increase in FE, but also abut the cost and complexity of the mod itself. This one rates really high in that thinking. But you have to attach it well from the first. My PS delete is similar: 1-3 mpg for merely removing a part is pretty damned good return on investment.

UltraGauge.

That really helped make me more efficient. The grille block made the car itself more efficient, though.

Hard to say what was best for FE but the one with the really obvious and welcome improvement was the grille block/engine compartment insulation combo. It was especially effective back when I had a daily commute: instant defroster and heater at the end of the day and of course not such a brutal cold start with all the evil that brings.
