I know!
Although there are some women that I could learn from about cars and trucks! LOL

I had a K&N filter in my last focus and it added about 3 mpg average. I will probably get another K&N. I have a K&N in my truck and I have the K&N reconditioning kit.

I am going to the Casey's in town too fill up with premium next fillup.

Thanks for the tip!

ps. I will wait to see if my wife notices any difference???

All I have done is a drop in filter from aFepower with the lid on and started running 93 octane.

Now like I said this is just a 15 mile stretch we drive and what I have averaged. Have not had it down interstate or highway since I changed a few things. Before I changed the filter and octane I was getting around 30 to 35. I had a lot of variance in it. Now I am between 41 to 43 on a consistent basis.

All grades of gas are winterized in much of the country, so long story short no.

The direct impact in energy content is said to be less than 2%, so most of the loss in fuel economy is related to the other factors.

If you parked in a heated garage or used an engine block heater to pre-warm the engine coolant and oil to near operating temperature the mileage would not suffer as badly. The car has to run rich when cold in order to warm up and get the engine to operating temperature where it can be more efficient.

Minimize idling and engine warm up times to increase fuel economy.

How can I improve the mileage? I am running standard grade at 87.
Move the post as required please.

Another reason it's difficult to determine the degree to which seasonal gas formulations affect mileage is that other factors come to play, and with greater impact. An ice-cold engine needs a "richer" gas-air mixture to fire up and idle, and until the engine reaches operating temperature, you're burning more gas compared with startups in the lazy, hazy days of summer. Factors other than winter-blend gas can cut far deeper into mileage — by 20 percent or more — according to the EPA. These include excessive idling (no need to "warm up the engine" in cars made in the last decade or so) and poor road conditions, as well as non-seasonal issues such as lead-foot acceleration, traffic congestion, engine efficiency (need a tuneup?), tire pressure, head winds and hills.
