Hey All,

I have an 5-speed '11 Aveo LS which I had the dealer install A/C. I know that A/C tends to be parasitic, but I was curious if anyone knew by how much?

I just ran a 300 mile highway trip @ 75 mph w/ A/C 4 passengers and a cooler and got 27.5 mpg.

Today I ran a 94 mile highway trip at 64 mph w/ A/C and just myself and got 29.4 mpg.

I feel this milage is extremely low considering I had an 2.5 Altima S as a rental and I did 75 with A/C and got 32 hwy. I am just curious if this sounds right for other Aveos with A/C?
