Bad gas mileage all of a sudden. 16mpg or less.
All of a sudden I have been getting really bad gas mileage. Usually get mid 20's mpg. I am now getting around 16 mpg.
I am supercharged but the mid 20's were even when supercharged. I have been driving it much less aggressively now that it is cold out as well. No boosting or anything.
Get down to have a tank at about 85-90 miles usually. Prior I was able to get close to 300 miles on a tank.
Tire pressure was slightly low. 30 psi or so in the rear. I wouldn't think that would be nearly enough to lower the mpg's that much.
What are some common things to check? I am not running rich either as I have a wideband to watch for that.
I am getting tuned on Monday hopefully but something seems to have changed to cause the bad mileage all of a sudden.

Have you noticed anything else outside of the gas mileage with the car? Have daily temps changed? It could be a combination of frigid temps and winter blend gas.

I don't check my mileage. It varies too much depending on the right foot.
A couple weeks back I used 1/2 tank in an hour. I was getting on it a bunch and racing.

Thing is my right foot has been taking it very easy and getting much worse mpg's than when when I was flooring it all over the place in the summer boosting.
Maybe that winter blend crap is really that bad lol.
