Car maintenance mythes


good read.

 

good stuff right there, I've always told people about higher octane, and the A/C, no one believed me lol

 

Ah! Consumer Reports the authority on autos. The same rag that tested an all season tire and summer high performance tire and gave the win to the all season tire. Because it was better in the snow and rain!

 

Myth: Air conditioning will hurt fuel economy

Reality: There has been much debate about whether to drive with the air conditioner on or keep the windows open in order to save gas. Using the A/C does put more load on the engine, but in our tests, we found just a slight decrease in fuel economy and no measurable difference when opening the windows (open windows do increase aerodynamic drag). However, using the A/C helps keep the driver alert and more comfortable, which is safer for everyone on the road. We say, just use the A/C and don't worry about it.
