Having the snow button on will drop your gas milage. The front wheels are being driven a lot more than in normal mode.

You don't really need the SNOW button on all the time. For the most part, i drive in Normal mode, and only switch to SNOW if there is a situation where i need the extra traction of 50/50.

 

Do you notice much worse MPG in the wintertime? I noticed a drop of 40 miles per tank compared to summer averages.

 

Yes, the volume of gas contracts in the cold weather. In the underground storage tanks the gasoline is in 60 degree range. Once in your tank at 10 degrees F you'll get a little shrinkage.

I have also heard the additive in winter blend gas hurts fuel economy.

 

Correct. Winter Blend Gas does result in a slightly lower MPG.

I usually get around 24mpg highway (speeds of 80-90mph) and I maintain my car pretty well. Lately I have been tracking my gas usage as my driving habits have changed (new city and new job) and i'm averaging 20-21mpg combined. Not bad for an 06 X, but not great compared to other cars I have had.

 

Reviving an old thread. I remember reading this back when I bought my 05 X in 2019.

I was originally getting 16 mpg city, 18 combined and the most I got on the highway was just over 20 mpg.

I’ve fixed three vacuum leaks, cleaned my MAF/throttle body twice and I have an AEM dryflow air filter installed. I also regularly put through a bottle of Redline SI-1 fuel system cleaner.

I broke two fuel economy records this week: 23.4 mpg combined and 26.8 mpg highway. I had never got above 25 mpg, let alone 26! I know these vehicles are performance oriented and not intended for those worried about fuel economy but I’m excited to see all the little maintenance efforts pay off. Of course I have to thank those on this forum that give their suggestions and experience.

Hoppy Easter everyone!

 

I just broke in a new clutch and now that I can get on the throttle again I managed to get 11 mpg city driving on a half a tank of gas, does this count?

Probably due to my air filter being absolutely FILTHY, like laughably dirty. Cleaning it today.

 

As long as you are filling your tank back up to the same level as it was before and calculating by miles driven per gallons refilled, doesn’t matter how much of your tank you go through. I have the fuel filler neck issue where the pump clicks off even when it’s 30% full so I manually fill it up, then pull the nozzle out and continue filling until the gas comes all the way up the to top at the cap. This way I know I’m always starting off with the same amount of fuel as the last tank, +/- a negligible amount.

Very happy I bought the reusable filter. Fun to clean, far cheaper long term and better breathing. I also installed a plenum spacer last summer and my fuel economy actually increased slightly. I understand the first two cylinders breathe and burn better but I wasn’t expecting an increase necessarily.

 

Yeah I've been a big K&N fan since they became popular. Good trick for drying them out after cleaning and before oiling is to set them on one of the floor vents in your house if you have central AC, otherwise just lay a box fan flat on the ground raised up on some 2x4 wood and set the filter on it.

Only takes a couple hours to be 100% dry.

 

I don’t oil mine, just wash it out with soap and high pressure water. I didn’t want to get into the oiled filters, personally.

First time I washed mine out I just left it sitting out for 48 hours. Tossed it back in and started the car, the car was sputtering and felt like it had trouble breathing. Looked in the air filter housing and there was water drops running down. Thank Christ I didn’t hydrolock my engine....

Never again. I put it up against a space heater for a few hours and it’s perfectly dry.

 

You're not going to hydrylock the engine with small droplets, only times I've seen it is people driving through big puddles or out off-roading through ponds/ocean when the intake pipe is literally sucking ALL THE WATER IT CAN and you pull the heads and the cylinders are completely FULL of water.

Worst you'll do with a wet filter is steam clean the top of the pistons, which is still bad, but not going to hydrolock.

 

There was droplets in the air filter housing and intake tubing once I REMOVED the filter, and the filter itself had water dripping down from it. When I first had picked it up it wasn't wet or even moist but the vacuum pulled out all the water still sitting within the filter. I honestly thought the car was misfiring.

Nice so I gave my pistons a good cleaning?? Thanks for the tip!
