Wow, I Got 48.57 mpg - Toyota Yaris Forums

So please tell me how I can get 48 MPG. I only seem to get around the mid to upper 30's. 35-37ish. What again is DFCO. Guess I should read the threads. Let me know.

it seems the people saying that DFCO doesn't work for them are the ones who have noted coasting in neutral and not having the car in gear.

Correct me if I'm wrong, but the Yaris will automatically switch off gas if you're rolling along in gear and have the foot off the accelerator. So, why's Bailout going on about manually switching off the engine while costing? If the Yaris has DCFO, that should be necessary. right?

I'm a delivery driver and spend a lot of time on the road. The biggest hazard on the highway is the trucks. I had two situation where a truck wheel came at me from the side while I was in the fast lane. One time, all I had to do was go down hard on the brake and let the tire roll harmlessly in front of me while making its way into the ditch. The another situation, I had to speed up and let it pass behind me (thankfully, the government is cracking down on these truck driver and I've yet to have a tire come at me for the last several years). In another situation, I was stopped at the lights, under a downhill, on wet roads, and had to peel out into the shoulder to avoid an LH car that was in a 4-wheel lockup while sliding down the hill.

My fuel economy has never gotten better then 37mpg (us), but that has since changed for last 3 fill-ups and I'm now getting over 38mpg. In the past I used to let the car roll-along in neutral at every opportunity, but recently (since I heard about DCFO on this thread), I decided to leave it in gear (assuming engine braking wasn't too drastic) and now I'm getting over 38mpg!!! Which is shocker for me, since the car has done over 50,000km and I'm just now starting to get into the 38mpg range.

Turning off the ignition is even more drastic, with normal DFCO, the fuel will kick back in when the engine speeds gets below 1,000RPM. With the engine off, it will stay off until you gently roll to a stop.
