Thread: Gas mileage

MPG should be slightly better overall in mixed normal driving. That was my experience with vvl.

If you are smart and do a little pulse coasting and cruise control you can do significantly better without being an annoying hypermiler or going 45mph.

You are right. I made my calculation wrong.

Best ive did was 5.9l / 100km, which is ~40mpg.

Calculator - l/100km to MPG / Litre / MPG / MPG to l/100km / Liter / Convert fuel efficiency - eForecourt.com

jagy, do you know what percent of ethanol is in your fuel? I know in the US, I see "up to 10% ethanol" advertised.

Ive just done a round trip with my Autech.

got 715km's from a full tank of fuel, around 444 miles. worked out around 41mpg

I brimmed the tank set off, and brimmed the tank again at the same pump once I got back.

put in 49.7Litres of fuel.

this is 90% highway driving mixed with some thrashing through countryside

Driving a B/N series stock sr20de powered car carefully on the highway around 55-60MPH will net you 35-40mpg. Going higher than 60mph will start to increase consumption drastically because of the geometrically progressing air resistance after 60mpg (100km/h). Lowports in good condition would be more economical than highports, but may be equal to VEs.

So if I go VE I can expect a slight diff in fuel consumption but not much as fas as I understood, I know it's all about how much time do you spend in the high lobes zone.

I'm just trying to find reasons to swap my flawless lowport

i just got 200mpg on this last tank.. i know my o2 sensors bad an goes rich at idle.. but during driving the afr's are dead on..

i spend ALOT of time on the high lobes .. shit prolly over 1/4 of that tank was used for fine tuning my afr's again lol.

i've gone 300 miles on 3/4 of a tank.. had to refill at 1/4 tank (next gas station was to far to chance it lol) but if i hadnt filled up then i could have prolly gone 380+ miles on that tank.. that was all hwy with only a LITTLE high lobe action an that was at 70-80mph.

I get 19.5 MPG on my VE without even hitting VVL.

What ECU r u runing?
