Good news though by using dwl technique and no shoe I'm looking at a 44mpg tank so the technique is working excellent so far
ScanGauge doesn't tune the engine; won't override the car's computer.

Scangauge II will display four out of about 20 different gauge items including mpg. I use it for volts, engine coolant temp, and throttle position but there's a lot more it will show. ScanGauge e only displays two items but you have a variety to choose from.

As far as trying to reach EPA, sometimes it's a challenge (that's not news). My son's '05 Elantra doesn't achieve its EPA # either. Do shift as low as possible. It's a performance car of sorts so it wants to be zippy; do what you can to keep the rpms down. But you probably don't want to go near lugging it while breaking it in.

I'm not going to be any less of a hypermiler, even if my sig stops calling me one.

The EPA rating is just a benchmark. That's all.
Your MPG may plummet, but if it drops from 30 to 24, and you cut from 90 miles/day to 20 miles/day, you're still saving gas.

I'll be lucky to see 20. I'll also be driving maybe 2 or 3 miles a day, getting some great use out of the bicycle as well.

Unhappy

UPDATE

So i was ecstatic for this tank of gas i was at half tank and nearly 300 miles in an likely would have smashed a 500 mile tank and been about 44mpg

On my way home from a 12hr night shift i was lugging along keeping constant throttle positron and threw a cel.. didn't notice driveability issues until i hit a stop light and realize i had power loss at low rpm...10 miles later knock and plumes of white smoke... Towed to dealer and 2 Pistons lost compression and oil soaked plugs...

Still awaiting final diagnosis but a new long block is on order... My break in was about 3k where i drove somewhat aggressive at low <4k rpm i am so confused at how low rpm hypermile techniques would blow my motor

You didn't. Manufacturers have warrantees because they don't think the parts are going to break in the first place, but sometimes they do. Don't worry about it.

If you were lugging the engine, it *could* have accelerated an already present problem.

I agree with Charlie - cars have warranties for a reason. There's always a percent of manufactured items that do fail; you happened just to be unlucky enough to get one.

Many people here have noticed a drop in mileage when new tires are installed. Its a pretty well known fact that having less tread on the tire leads to lower rolling resistance.

Maybe I'm buying better quality tires than some others do. Also I don't always wait until tires are worn down to the tread wear indicator to replace them. For me safety is a higher priority than hypermiling.

How much tread do you need to feel safe? In a New England winter it's nice to have a lot, but in general you don't need much. Any tread at all is usually enough.

3 miles per day, 5 days per week @ 20 MPG = 0.75 gallons used /week.

90 miles per day, 5 days per week @ 30 MPG = 15.0 gallons used /week.


I'd say you'll be coming out ahead.
