Dropping MPG

[daddycreswell]

Over the last 3 weeks I've gone from 11.5 mpg on average to 10.2. Any ideas? Oil life shows 20%. It's driving me crazy/

Not sure down there, but up here, we get "winter blend" gasoline, and it kills any MPG you were getting...

I thought about that, but it's just funny it started over the last couple of weeks, not really sure when the swap over is but I would have figured it would have been a while ago.

Do you have a tune on the truck?

Has it been colder recently?

No tuner

Has it been colder recently?

Not really, up and down. 50 one day 30 the next

Then quit driving like you're playing GTA.

 

[Jimbo]

If no tuner, maybe you should try a battery reset. Relearn your parameters... and then see what happens over the course of the next week.

Ha, if that was the fact I'd have the thing wrapped around a pole somewhere.

False. You wouldn't be driving, as you're never on
