So I was just wondering what other people were getting for gas mileage with their Disco II. I currently am getting between 13-14 around town with a mixed driving of freeway and side streets. And the best I have gotten on the highway was 15.1.

 

I get 14-16 mixed daily driving with my 181,000 miles DI, 22-24 mpg expressway on long trips.
I use Shell gas 90% of the time and I have noticed that my mpg drops if I use lesser quailty gas.

 

So how many miles on your truck and what octane gas are you running? Has it been tuned yet, with new wires, do you ever use any gas additive.
In Colorado at 600 feet I average around 14 in town, 15,5 back and forth up into the mounts to run trails and 18.2 at 70 or less on the highway.

 

my 04SE gets in the 14's in town and low 18's on the freeway between 65 and 70.

and it has been tuned up. doing the fluid swaps in the tranny, tcase, and diffs to all synthetic. might be worth a bit more mpg's

 

I've been getting 15-16 on my commute, which is mixed driving.

 

I get 15-16 in town and low 20's on the highway.

 

Used to get 13 combined, since I replaced a bad CKPS, now getting 16.
Taking a long highway trip next week, looking for 20+!

 

I use 91 octane and I have not done any tuning or upgrades since I have had it since April. I did have to do some work in May on it, it had to had the t-case resealed, head gasket replaced, valve cover gasket replaced, radiator replaced, some radiator tubes replaced, and the front brakes replaced. Which I am just about to hit 100k miles on it. What do you guys recommend do to get better mileage outside the common change your driving habits? How much do you think it will cost for the supplies?

Also I know in the Phoenix area, we all have to use oxygenated fuels, which is a bit of a killer for mpg.

 

On Shell 93 Octane, fresh fluids in everything I'm getting about 15 across a tank, mostly city.

 

Cranks sensor has nothing to do with increasing or decreasing your fuel mileage, something else must have happened.
