Best MPG without EOC and P&G ??
 

Hi Guys n Gals,

I am curious as to what MPG's you guys are able to achieve without the usual EOC (and stop lights) & P&G ?

I am struggling to get under 5.5l/100km in a 1.3L DOHC weighing 900Kg with me in it, and am wondering if that is average, great or unbelievable ? :o

I am planning on EOC sometime in the future, once I can make it electronic, aka Prius hands off style would be nice, but till then I would like to see how low I can go and have the feeling that this MPG is potentially only average.

The engine has a few miles on it (140k), but seems mechanically A1. Though it does need a new clutch but I'm not expecting that to change my MPG figures much if anything?

I have a wideband on it and other than being in closed loop for 95% of the time, it barely goes below 14:1 with my driving style. I know that doesn't mean much given load and bsfc etc..

Anyway, feel free to post up some non EOC and P&G numbers?

I'm curious as to whether or not I should be doing better given the car I have?

:)

I am doing just under 40 mpg (about 6 l/km) in a 1.4 l Nissan Versa. Lately my driving style has been to coast to stops idling in neutral and occasionally coasting down hills, idling in neutral. I have done aggressive engine off coasting in the past but not in the past few tanks.

i have a grill block and a modest spoiler.

At this point, an oil heater would probably give me good results, and I want to build another boattail, which is very effective.

It sounds like you are doing a good job with 5.5 l/km. Does your vehicle have a US rating? Generally we compare our results to the US EPA rating, it allows comparing mods and driving techniques to an average rating.

No EPA rating only an ADR rating of 6.6l/100km for City driving and 4.8L/100km for Highway, which I can put up the test procedure if someone is interested. Done on a dyno with correction factors applied after.

Can't wait to fit my MPGuino to see if I can really get 4.8L/100km on the highway.....

My last two vacation rentals were automatic transmission cars that I couldn't EOC in. I did P&G them, but have no idea whether it helped or hurt. I averaged close to 5.5l/100km in them (42 mpg in the Toyota Yaris with 1.5 l engine and 43.7 mpg in the Kia Rio with 1.6 l engine). Since I was doing a lot of long distance, warm engine highway driving, I'm sure my mpg would have been worse if I'd mixed in much city driving. I think you're probably doing pretty well to get 5.5l/100km without EOC or P&G. The only other thing I did for hypermiling was to keep my top speed around 90 km/hr (55 mph).

I've done 57.51 with the engine running the whole time, no pulse and glide in my 1997 Tercel, about 40.1 in a 2010 Ford Fusion rental and a not very impressive 32.8 in a 2005 Dodge Stratus.

It's certainly not too shabby for a petrol engine ;)
But given the weight and displacement of the car, it can get better :)

If it's worn and slipping, it will affect your mileage.


Which hypermiling tricks are you applying already ?

Why wouldn't I EOC? It saves loads of gas around town. But to answer your question, 78mpg @ 69mph on the interstate on a hot day with no A/C and the windows up. I've also done > 100mpg segments on the highway, but of course I'll EOC down the offramps, and extensively on my way to the highway.

Feel free to explain how? Especially in a petrol car with more displacement and weight? :(

I'm running the baby 4E-FE.. :)

Even if I can achieve the highway rating of this thing, that's only 49 MPG....

Apart from EOC and P&G there isn't much I already don't do from that list....

I think the MPGuino, once calibrated, will help me greatly so we'll see.

:)

In my matrix, before my big mod add on in Aug I could get 42-43 MPG. Now I can get 44-46. If I work on it I have gotten 50 :)
