I travel close to 40 miles each way to work and back, no traffic, all highway (speed limit is 55) except for 10 minutes near my home (2 stop signs, 5 possible red lights, 25-45 speed limits). I started watching MPG's after my second oil change at 7500 miles. I have a CVT and have never been below 38 in the summer, 35 in the winter. I have 33K miles now.
*When starting from a stop, keep the tach BELOW 1900 rpm. Start by quickly pushing the peddle in and watch the tack "jump" to 1900 then back the peddle out until you hit 1700. Hold at 1700 and increase if your going faster than 45. This will give a nice acceleration all the way to 45. It's not break-neck, but it's faster than a Chevette or Metro. If your accelerating to a different speed, look to see what your "cruising" tach is at that speed. For me, 55 is 1900, 45 is 1700, 35 is 1300. I back the peddle out until I hit that RPM and reach the speed that way. I can tell by the sound of the engine now.
*Synthetic oil MAY save MPG's depending on what crap you were using. Don't expect synthetic to save everyone money, it mostly does that by extending change intervals. If your using the sludge at a shop, you have a higher chance of seeing an increase by switching.
*Remove all excess weight... EXCESS, not your spare tire (unless you're really confident)
*Leave your windows up above 45 MPH. If it's hot, go ahead and use your A/C. The 1-2 MPG drop from using the A/C is the same as those large windows ruining the air flow by opening them, so your better with the more comfortable A/C (Consumer Reports did a study on this as well as the MythBusters). Below 45 MPH, open the windows and shut off the A/C. Also, don't use "MAX" or "Recirculate", just normal A/C and vent. Use Fan 4 until the car is rather chilly, then turn off the A/C but leave the fan on 4. When it starts to get toasty, turn the A/C back on. I don't live in Arizona, so this won't work everywhere
*Shut off the car if your going to idle for more than 30 seconds. Hypermilers say 10 seconds for fuel-injected cars. Your choice.
*Use neutral on downward slopes, stay in drive on drop-off hills. This doesn't save gas, it saves brakes. For maximum gas savings, neutral when coasting... always. I have a CVT, remember.
*CAP the car! I drive on very hilly terrain. I cause many horns, middle fingers, and the sweetest things said about my mother. I use CAP - Constant Accelerator Position. I go down hills at 64 and up the other side at 52. This, along with lower-rpm accelerating, is the BIG MPG booster! The others are so-so. My target speed is 57.
*57 mph is the optimum MPG speed I've found. Others may be slightly slower or slightly faster. At 57 mph, I use .736 gallons/hour. At 85 mph, I use 1.645 gallons/hour. The CVT was "geared" for 55 mph, the EPA highway speed for MPG testing. Way to go Jato! This gives excellent performance, though, as I've never had an issue passing until gas hit $3.75, now I won't, but I could I wonder if the motive was to have a very nice launch for passing capability or a nice high MPG number under highway (2007 and earlier testing standards). My sticker says 38, didn't they lower it to 36 half way through the 2007 model year?
BTW, this would work on virtually any car. With gas at and over $4/gallon in most of the country save South Carolina, any little bit helps, no? I drive about 40 miles to work with 36 of them highway. I used to get there in 34 minutes at 80-90 MPH. Now I get there in 39 minutes at 57 mph. I used to fill up 11 gallons every Tuesday, now I fill up 8 gallons every Tuesday (give or take 1/4 gallon). $12 bucks a week, is it worth it? Depends on you, really. I'm getting ready for $6 a gallon. At $7, I buy a Civic.
