[WTF]

hey i was wanting to know if any body could help me figure this out i took the truck in to the stealer's cuz i thought the injectors were bad due to some white smoke and mpg going down so i get the truck back and they told me the fuel line they replaced last time was leaking and they tightend it up and said it stoped but im only getting 11.1-12.9 now and i want it back up to 16-19


Thanks for the help

Dirty filters, air pressures, bad alignment, or mass air sensor

change fuel filter, get the injector work checked out by a third party shop and see if maybe the dealer fd up somewhere.

were you hand calq.ing?

 

[WTF]

yeah i forgot about the air filter for once and now i rember why i didnt do it last time plus the guys at my stealer's are (good friends that i do work on the side for) they just broght the tec2 by the house and the injectors are all good (for now) and im hoping it was the air filter + fuel filter but i never had a drop like that just on those 2 and i got 60lbs in all 4 and the alignment was checked 4 days ago as for the mass its been bad for a good 8 months i just need to go and sing for it at the stealer's
and i check fuel milage every time by hand

winter blend diesel? im about in the same MPG boat you are...

 

[WTF]

is that why diesel is 1.98 and gas is 2.27

I don't know if that is why diesel is cheaper than gas I always seem to remeber winter blend diesel being more expensive than the summer blend. But I have not been in the states in the winter for 3 years now. But I do know that my economy sucked witht he winter blends.

 

[WTF]

i never knew there was a diff blend and i remember diesel uset to be alot cheaper then gas for the pure fact its a bi-product of gas

but its not a bi-product of gas...matter of fact there is a lot more work involved in making diesel now days.

also diesel prices go up in winter because the demad (so they say) for heating.

our diesel up here in Alberta is finally cheaper than gas again too.

yup out of every x amount of crude oil x amount of different products are made from it and gallon to gallon crude oil produces more gas than diesel. just a little fun fact for you now back to your mileage

 

[mmangels22]

weird for sure

well the amount of gas made out of it depends on what kinda oil it is seeing i was working with heavy stuff you could fold and break chunks off of it and i worked from there all the way up to water

and yeah back to the fuel mileage is at 11
