#54 of 103 2007 SX4 with 7k miles by harleybabe6 Feb 29, 2008 (11:17 am)
Any ideas on why my SX4 doesn't get over 20.9 mpg average ... the number hasn't changed since April of 07 after I had the car three months. It went up to 21.2 for about a week in September and then dropped back again. Didn't even change on a 90 mile all highway trip! Friends with the same car are averaging between 23 and 26 city, never mind hiway mpg! Had it to the dealer once hoping it was a computer firmware issue. Am taking it back again next week. Any suggestions? I like the car but not the mileage.... Replies to this message: gregg_vw (Feb 29, 2008 12:54 pm) harleybabe6 (Mar 24, 2008 6:02 am) lamronh49 (Mar 24, 2008 7:50 am)

Replying to: harleybabe6 (Feb 29, 2008 11:17 am) You sure you have it in "D" and not "3"? If you have the manual transmission, are you upshifting quickly to the highest gear you can use withour lugging? Do you keep it in set in 2WD when the highways are clear? Are your tires properly inflated? Do you routinely have any extra stuff in the car (weight cuts mileage more than anything, especially in smaller vehicles).   One more thing: if you are measuring by the computer read-out, first re-set it before a highway trip and see if it doesn't show better mileage (a 90 miles trip is not going to change the overall average if you have thousands of driving miles in that 20.9 mpg readout). Secondly, test its accuracy with the old fashioned keeping track of miles between fills. Replies to this message: harleybabe6 (Mar 24, 2008 6:02 am) lamronh49 (Mar 24, 2008 7:50 am)
#56 of 103 Sedan MPG? by lamronh49 Mar 22, 2008 (9:34 pm)
Has anyone gotten some miles on their sedan automatic, and recorded MPG numbers? BTW, the computer is not always correct, the most accurate way to measure MPG is to divide miles driven by gallons used, when you fill up. I'm looking at a sedan, and would be happy to read they can consistently get over 30 MPG on the road. Replies to this message: steve_ (Mar 22, 2008 10:19 pm)

Replying to: lamronh49 (Mar 22, 2008 9:34 pm) That was true in the old days (a few years back, in other words). The mpg computers are very accurate nowadays, from reading posts in the various real world mpg discussions around here.   Doesn't hurt to cross check it with the manual system now and then. Even that isn't always accurate since most people don't fill up from the same pump every time nor do they click off at the same time when the car's tank is full.   We do have some Suzuki sedan mpg discussions here:   Suzuki Forenza Real World MPG   Suzuki Verona Real World MPG

Replying to: gregg_vw (Feb 29, 2008 12:54 pm) tires are properly inflated. No extra baggage/weight. And I normally am the only person in the car. How do you "reset" the mileage computer? Replies to this message: lamronh49 (Mar 24, 2008 7:50 am)

Replying to: harleybabe6 (Mar 24, 2008 6:02 am) There must be a reset button somewhere in the speedo area. Otherwise check your owner's manual. I reset mine at every tank, try to use the same pump, and the same two extra jolts once the cutoff has kicked.

Replying to: perry99 (Nov 02, 2007 8:24 am) I'm also having the same problem. My first 2 tanks of gas is averaging 20.7mpg. I'm "gently" driving it, no extra load (just me commuting everyday), tire pressure ok. I don't know why mpg isn't great. can anyone advise? does a car just use more gas when it's brand new? should i talk to the dealer?

Replying to: qtlilpanda (Mar 30, 2008 7:00 pm) That's about right for a brand new SX4 automatic. It will improve after a few thousand miles. Highway mileage will be better than that. It's a relatively heavy AWD car, so you cannot expect Fit or Versa type mileage. But they are lighter, don't offer AWD (or stability control(.

Replying to: qtlilpanda (Mar 30, 2008 7:00 pm) Well, as it turns out, the computer DID need to be reset. Now it's showing anywhere from 22.6 to 24.5 city ..... just hold the two buttons on the right for about 5 sec and it will blank out and then all blank dashes will appear. That resets it..
