Really bad MPG since winter hit??

[Moezer]

i put air in the back 2 tires tonight, my wife drives the x5 mostly and i tell you she has a light foot lol


ukrcan, lol in the summer days i was getting 650 to 750 with 1/4 left in the tank my dash reading thingy was reading 11.2L per 100 kms and with 1/4 tank left the dash was reading 160+ kms to E lol now its around 13.5L to 100kms :S

whats shocking to me is that my 2002 jeep tj inline 6 gets the same damn mileage year round 300 to 350 if i push it to 350 lol along with my 328i in the city i get 450 to 550 and over 800 kms highway, but seeing the x5 average 450 and the light comes on just makes me cringe from what it got in the summer damn

I wish Shell had 0 ethanol here in Washington. Every grade has at least 10% at all the top tier stations. You have to go no name indy stations for the ethanol free. I'll stick with Chevron and Shell.
Wow, and I thought my wife getting 16mpg in our 4.6 was bad. I can tell her to keep up the good work now We've gotten 21-22 on the highway getting around 500 miles per tank (we try to fill up before it goes below 1/4).

At your own discretion, you could remove the cooling fan on the 4.4 and early 3.0 (late 3.0 has an electric fan) during winter. This helps the engine warm up faster and get better gas mileage. Make sure to store the fan vertical though. I leave ours off until end of May and I think I probably could just leave it off through the summer if we just stayed on the peninsula out here where it doesn't really go above 70 degrees and no traffic.

Odd, my 3.0 gets somewhere close to 800km per tank. It might be that I coast as much as I can and accelerate gradually. I haven't event started doing my mad scientist mods yet.

I once got 35 mpg in a 1/2 ton pickup, but I also caused a bad misfire, and some of my experiments have been... catastrophic.

I'll go middle ground on the X and let you guys know if I get any good results.

Do you guys get the oxygenated gas up north? We get it with MTBE in it and that zaps mileage.

moezer, I have noticed a huge decrease too but mainly because i've been running my x5 to heat up till i drive it away since its been parked outside so far this winter as the new garage is not uilt yet. I also moved from Airdrie to inner calgary and my kms/tank have gone from 650kms/tank to 450 kms/tank now
its crappy the winter we've had so far.

I was surprised by the x5 when I got it and I saw it was getting almost 800+ at 1/4 before the light lit up, in fact I was happy as hell when people asked me "oh wow 4.4 v8 must be a gas drinker" I loved the look on there face when I told them I was getting around 800km to a tank lol

Im going to see after I put the sea foam in it what I get on this tank.

the thing is on my 2002 jeep tj I have always gotten around 300kms a tank winter or summer so when I saw the difference in the x5i noticed a crack in my visa

[puddinboo]

city in the winter I get 15.5/100km, city in summer about 14/100km, highway in summer about 10.4/100km

I've only ever gotten 800-880kms out of a tank when cruising at 100-110 kms/hr MAX from here to Montana. I've never gotten anything near that in the city or even airdrie to calgary highway driving.
I think the X5 4.4 and 3.0 is an OK vehicle on fuel consumption but I have noticed in the last 2 years my consumption dropping a bit too. I use seafoam every 4-10 tank fulls to clean it out.
use it in your oil for 150 kms before an oil change too. does wonders
