nice ..... your mpg will drop in the winter time always its the fuel not the car. it what they call winter blend. heres what i found out

Cars using summer-blend gasoline spew fewer harmful emissions and get slightly better fuel economy than those using winter-blend gas during the summer months

The difference between conventional summer- and winter-blend gasoline has to do with the Reid Vapor Pressure of the fuel. RVP relates to the volatility of a gasoline. The more volatile a gasoline, the more likely it will evaporate as the temperatures rises; evaporated gasoline contributes to unhealthy ozone and smog levels. Summer gasoline has a low RVP and is less likely to evaporate when compared to the high RVP winter grade. The Environmental Protection Agency says conventional summer-blend gasoline contains 1.7 percent more energy than winter-blend gas, which contributes to the summer blend’s slightly better gas mileage.

The Energy Information Administration says the switch between the two fuels happens twice a year, once in the fall (winter blend) and again in the spring (summer blend). Summer-blend gasoline is typically more expensive to produce than the winter blend, and it won’t affect vehicle performance or the durability of the engine and fuel system, according to the EPA.

In many large cities as well as California and New England, the EPA requires the use of reformulated summer- and winter-blend gasolines. These RFGs contain oxygenates that lower RVP and other toxic chemicals even further than conventional gasoline.

How the shit did you get 30 MPG in your 2.5???? I had cruise on at 73 mph and was getting like 19.6!!!

Bad winter fuel + ski rack + winter tires. :( stupid shit! I'm barley gettin 21 average driving conservatively.

If your on cruise at 73 and getting 19.6 you have a major problem. Our 2.5 gets 27mpg around town all the time. Thats fairly heavy city driving too.

I'm at 213 miles with 2 less notches.
Dude there's no way u should get 19 when cruising at 70..

I drive mostly highway n hardly run into traffic.. I don't accelerate hard n get the speeds up to 80 n let it drop to 70 n keep accelerating gently.. I never go at a constant speed.. I dunno it has to do with anything..

Then again if I get impatient and drive crazy I get about 20-22 mpg

I think it's a combination of bad winter gas + bulky ski rack + soft brand new snow tires + high elevation in Utah. I'm gonna go and change my fuel filter on monday, take the ski rack off, check the tire pressure, and put premium so I'm using a little better gas and I'll get back and let you know if I notice a big difference!!

Save the hassle. Premium wont get you any better mileage. Well maybe a tiny bit more but the higher price dont justify it. And as for the fuel filter it wont change it either. Those ski racks will hurt mileage but should only cut off maybe 2 miles per gallon. As for elevation i aint gotta clue. Im from the state of high elevation.......Florida lol.

lol go ahead and replace it. at least its cheap. it wont get you any noticeable mileage increase. but hey change it and let us know what happens. Ii had 150k on my 97 maxima and was still getting 27 mpg before and 27 mpg after i changed it. same on my 09 hhr. 70k miles and 30 mpg before and after. Im just sharing my experiences. i have never yielded i mpg gain with a fuel filter change. Its all electronic.

Many ppl have there own opinion on that particular subject. If u use high quality brand, for me , I only fill at Shell, bp , mobil and chevron. I fill up about 3 to 4 times a month and out of those time fill up premium once. Ur gunna see alot of ppl gunna say our 2.0 / 2.5 L engine is made to take regular fuel / 87 and no need for premium.

I've used a fuel injector cleaner b4, Lucas complete full treatment. Out of all there other kind, in my opinion it's the less harsher cleaners out there chemical wise.

I am having the same problem. 2009 Mazda 3, turned over 100k and suddenly gas consumption went from 27 combined to 19. No warning lights, gas smell, etc. I ran the dashboard test with no issues. Seems like there is something on the electronic side that is not linking well..but again, no warning lights, etc.
