Default Gas consumption went up 25 %

25%++Its seems impossible but my gas milage has gone from 19 to 24.5 liters per 100 kms that 's about 10 miles to the gallon. The truck is in for servicing on a knock caused by a leak on the exhaust , but I'm thinking there is more to it .
Has anyone else had or known of this problem ?

So it went from sucks to REALLY SUCKS!

If the truck is knocking the system will be screwed up trying to compensate so it definitely could be your problem.

Also down here in October/November they start adding winter gas additives which reduces my mileages 2 to 3 MPG Highway, they probably do that up there also

Default Tis the reason for the season

I know here in Minnesota I have been using the remote start more then I was using it a month ago. Since I have had the truck my winter mileage suffers becasue of my idle/warmup times have increased. If that is not a contributing factor by all means start the mechanical inspections starting with plugs and air flow etc...




Enjoy the Ride!

Thumbs up got the answer

It turns out I had a broken stud on the exhaust manifold causing a leak and I don- know what but it's back on track , I think they must have reflashed the comupter as well,,buy the way under Warranty .

I'm thinking maybe an extended warranty may not be a bad idea.

Between warming the truck up in the morning and winter gas my mileage has taken a real dump! Oh well only 3 more months of winter!

Now check the MPG for a while and see if the issue is really fixed. Hope so !!

my truck hates winter gas, crappy mileage, rough idle, I am going to try a higher octane fuel and will let you know how it works.

Thumbs up Undate on Repair : gas mileage back to normal

IT has been a week now and everything is back to normal re the gas milage after repair , I'm getting 16.7 l / 100 kms overall,city highway or 14.5 miles per gallon
So if you hear a knocking sound for a few seconds on start up , start checking your mileage to see if it is spiking, it maybe a broken exhaust stud .
