I think it was only a few weeks ago when I made a thread about how my gas mileage was really good. But on my most recent fill up, it's been doing terrible.

Normally with 87 octane I get 18.6 mpg. And more recently I've tried 91 octane and made about 19.5 mpg. However on my last fill up of 91, I've been getting 10...maybe 11 mpg!

Truck is running smooth, no leaks, stutters, or anything, nothing seems to be wrong, but mileage just sucks on this tank right now.

I'm assuming and hoping it's just a fluke of bad gas from Chevron. I've never had problems from them before. What do you guys think it could be?

 

A driver so pissed off about his gauges and considering the sale of his truck with a heavier foot than usual?

 

hah, no I've been driving it real lightly

btw, I got the new gauges installed last night they work great
