Title: Club Member's Fuel Economy Thread
Post by: morrisman1 on 20 February, 2013, 09:19:56 PM
As much as making power is fun, in a weird way I find trying to get the best fuel economy satisfying too. There doesn't seem to be a thread for this so I thought I might start one.

Might as well follow a template of some sort:

Chassis: p11 wagon
Engine: sr20ve
Transmission: RS5F32V FM41
Tyre Pressure: 38/38
Performance/Economy mods:  nil yet
Driving Style: Economical, occasional blat, sit at/above speed limit
Urban Fuel (L/100km) 9.18L/100km - pre-daughterboard Manual
Highway Fuel (L/100km)  CVT = 8L/100km. Pre-daughterboard manual = 8.7L/100km. Post Daughterboard manual = 6.24L/100km (careful driving)

If you have actual figures (not like $50 lasts me a week type thing - thats useless) then please post up!

Well I never record mine, but with a rich tune and stop start small trips around town I don't get much more than 500km out of tank before the petrol light comes on.

Open road is waaayyyy better.

Urban Fuel (L/100km) Round 10km/L (best (unmeasured))
Highway Fuel (L/100km) 7.81L/100km (12.87km/L)

This test was when i first brought car i drove it from Porirua (wellington) to Mercer (south of Auckland) between full ups.
Since fitted a SR20VE head but haven't done any testing as im to poor to fill car to top then refill after test to get exact usage (only way to actually test your economy).  Hoping to crack 13.5km/L once tuned.

Chassis: 2000 Y11 Wingroad ZV
Engine: SR20VE
Transmission: Hyper CVT
Tyre Pressure: 38/38
Performance/Economy mods:  Nothing
Driving Style: Open road cruise
Urban Fuel (L/100km)
Highway Fuel (L/100km) 7.84L/100km (12.75km/L)

Open road test done only.  I feel this car with the Hyper CVT could be made very very economical as it sits at 2200rpm @100km/h. 
If i wasn't selling car to buy a house id fit SR16VE cams and tune it.  (im sure it can be tuned while keeping the CVT) id expect round 14-15km/L from this after thats been done.

Just thought id add that we should put wheel sizes / tyre profile
Smaller wheels/tyres will show higher speeds, and higher mileage and vice versa for bigger wheels/tyres

I dont even get 600 when i do highway driving and thats when im most economical.  Although i get my hopes up when i get over 300 for the first half tank. Second half never lasts long enough
Title: Re: Club Member's Fuel Economy Thread
Post by: morrisman1 on 05 April, 2013, 10:26:14 PM
Are the VE engines normally more economical than DE? Theoretically they should be I guess due to having less of a compromise with regards to camshaft profiles.
Title: Re: Club Member's Fuel Economy Thread
Post by: Jason Sayers on 05 April, 2013, 10:29:10 PM
I don't entirely drive slow

I get to the speed limit and stick to it..

My style maybe. Not completely stopping as I give way etc.

Plus. I live in Hamilton. Completly different roads. I get 350 km just to the top half tank

VE makes it easy to cruise round under 3 grand. i reckon you could really string out a tank on a VE if you tried.

I find with my sr18de you have to get it up to 4 grand to get to the torque out of the motor. that's not great on fuel really.

Just thought it would be interesting to see what economy people are getting between different cars with different configurations.


I have a 1996 Primera

5 speed SR20DE


L/100 at last fuel up: 7.58
City:Country ratio:     65:35
Aircon on around 45% of the time


I have to say I am very happy with that.

The car is stock standard  ;)

Our stock P11 TE-V did 8.4L / 100km on a weekend trip to Tauranga which featured some, er, energetic driving.  It has now done 220,000km and the economy is still the same as when we got it.
