Fuel Saving Tips

Modern A/C System DO use more fuel!

On my 2015 VW Golf, I've been carefully watching my MPG. Now that the temps are consistent and my driving is too, I can monitor my fuel economy with A/C on and off. My route consists of 70% highway. 4 total fillups have been monitored 2 with it on and 2 with it off. I saw 2 MPG LESS with A/C on then off. The new systems are more efficient, but they still will consume a noticeable amount more fuel, especially in city driving.
