Replying to: mattb4 (Jun 14, 2007 5:46 am) I am days away from my 2007 SX4 Auto... I hope MPG is close to sticker - aways expect it to be a bit less. Here's my three contributions to this topic: 1) Why the SX4: Cheap AWD, and in Minnesota it will help. 2) MPG: The SX4 is a lot better on fuel if you come from where I am = a supercharged 97 Grand Prix GTP, 0to60 6.8seconds = 16 MPG on Premium, 14 MPG on mid-grade (rated 26city 34highway) which may soon be for sale here. This is 'average city driving' - no lead foot, and no trying to be careful. 3) Here is todays humor / scary post: I test drove a 2008 SX4 Auto two days ago, here is the conversation with the salesman in the back seat: me: "Does the MPG display ever settle down and average?" as it jumped between 59.9 and 11.5... him: "If you press the button, it will switch to average." I pressed it... and it said 14.3 MPG. Not enough to scare me - It is nice to know the salespeople are not smart enough to press reset prior to letting a potential buyer drive it...  And that it sounds like it is accurate - not imaginary like on my GTP which always uses 2 Gallons less than the info center reports it used. So - for those of you who are interested in MPG - a car will always get the MPG as a reflection of how you drive - if you floor it alot, like test-drivers: expect very low. If you drive like grandma - you might, just might reach the sticker. (I got 32 MPG in my GTP on a 240 mile all highway trip, babying it all the way. I got 38 only once, me only in the car, back seat removed, and watching my (added) vacuum gauge and not letting it drop under 10 even if it meant slowing down going up hills... from full to very nearly empty on a very long road trip, cool outside temps, night, far from cities (no traffic) and almost flat road: 55 flat, slowest hill around 25 (just a hint for those who don't know how to get good mileage if the gas gauge is on or near 'E' - (if you do not have a vacuum gauge) keep your foot at the same place going up a hill as on level ground. I.e. at 55mph, an average hill might slow you to 35mph, but keeping the throttle at the same place will mean you won't increase vacuum, drawing in more fuel, and will save you money). I learned a lot of old tricks many many years ago when I was playing with cars in H.S. like on a carborated car, replace the carbs secondary vacuum motor (which opens the secondary when you floor it) with a choke cable and spring. Choke in and primary only = better mpg. Choke out and spring tension = cam controlled faster secondary... a bit faster. Not really sure it that worked, but with the air filter top replaced with a aluminum plate from a camp set with a hole drilled in it - it sure sounded faster. Cars were toys back then... Not sure what I'll do on my new SX4, definitely add a vacuum guage, probably oil temp too. Another hint: did you know oil temp rises when it needs changing? Right around 4 to 6000 miles it would go up 20 degrees, although I typically, usually change it at 3000 anyways. Except on my GTP which tells you when to change it - I change it at 50% life remaining - its easier. Other advice - (yes, I'm full of it - take that any way you want ): If your thinking of accessories - skip the wing. If it protrudes above the car - you will get less MPG. Odds are very high it does nothing - most wings, like more than 3 inches wide, do little under 100mph. If they are on the car surface, you can bet tubulence around the read far exceeds any pressure on the wing. I got better MPG without the tail on my GTP and no noticeable affect with or without it. I might get the arm-wrest... maybe order the wide side molding. Ok, thanks for letting me type - a favorite hobby. Glad to share, don't officially know if anything I said is true... but I think it is... (I do have a Minor in Automotive Engineering - at least its fun to say... and true...). Todd Free oil changes will be nice. Wonder if you could pay like $10 extra for synthetic?

Just got a 2008 SX4 Crossover w/Touring II, automatic. First tank of gas got me 23.6mpg. (About 75% city/25% highway.) Second tank of gas got me 27.7mpg. (About 10% city/90% highway.) Both with "gentle" driving. Hopefully this will improve somewhat as it breaks in more, but I'm not necessarily expecting a big difference. I live in the Seattle area, so there are a lot of hills that need a lot of gas to get up, in contrast to flatter areas where it's easier to do gas-sipping cruising.

Replying to: perry99 (Nov 01, 2007 9:31 am) I've been a fan of the "gentle" break-in on my last 8 cars. I try not to drive'em over 65 or at a continuous speed for the 1st 1200 miles. Hopefully your mpg will rise 1 or 2 more on your highway runs. |

Replying to: crazedcommuter (Nov 01, 2007 3:29 pm) Yeah, the instruction manual recommends the "gentle" driving (no fast starts, hard brakes, varied speeds) for the first 600 miles. On another gas related topic, it's odd that the gas tank size is a bit uncertain. A lot of sites (including the Suzuki Auto site) say it's 11.0 gallons, but the manual says it's 11.9 gallons. It also says it's 45 liters, which is closer to 11.9 gallons, so I'm inclined to believe it's 11.9 gallons, and that the 11.0 entries are from accidental dropping of the 0.9. But I don't want to deliberately run out of gas to test it though

Replying to: perry99 (Nov 02, 2007 8:24 am) I was hoping Suzuki would expand the tank to at least 13.5 gal. BTW, do you have enough miles yet for an mpg report?

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....

Replying to: harleybabe6 (Feb 29, 2008 11:17 am) 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.

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.

Replying to: lamronh49 (Mar 22, 2008 9:34 pm) 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 |
