Fuel Milage On A Rb25De

[WMDC35]

i've had a number of de daily drivers, seem to be pretty hungry 12-13l/100km (around town driving mostly), going along with the under engined thoery the 25s used less gas than the 20e & 20de and go alot better

YEs ^^^

Funny story, back in the 70's my old man had a XW falcon ute with a 302 in it (bought it brand new in 1969)

all his mates went and bought datsun utes etc due to rising fuel costs, they were stoked at getting 16mpg...my old man laughed because his 4.9L V8 was getting 22mpg around town lugging a shit load of tools around the place

520kms per tank - 99 % highway driving

I get 430km before I pussy out and refill.

difference between NA and Turbo is sfa

This, but how much worser is the auto compared to manual?

Extra 2-3L / 100km?

[mad082]

depends on type of driving and driving style, but it certainly won't be 2-3L/100kms different. flooring it everywhere may be 1/2L to 3/4L worse, highway would be less

^Would say more toward the 3-4L/100km from experience

[mad082]

you sure you didn't have a mechanical issue? if you're using 30 to 40% more fuel then that isn't right

[Mayuri Krab]

Its just that the the lowest I can get my auto down is 10.5L/100km & that is making a 430km trip doing about 110 - 120km/h (mostly) the whole way. & then I read people claiming that they get ~8L/100km doing mostly freeways (I assume it would be manual).

In the city mixed driving I can never get it below 12L/100km (always hover around 13.5L/100km)...

& now with mainly bumper to bumper traffic it shoots up to 16.5L/100km.

Car has the usual bolt ons (exhuast, intake, bleed valve to 10PSI) & a basic tune with SAFC 2.

don't pay too much attention to other peoples fuel economy. individual driving circumstances, etc will always come into play. plus things like individual speedo error, engine condition, etc, comes into play as well.

Yerp pretty sure.

Had auto: R33 GTS, R32 GTS4, R33 GTST... Dat auto box man, saps fuel. Same applies to sister's S13.. That's auto and f**ken sheet on the jooce.

i do 10l/100kms easy.

that said, mines a neo.

last fill up. 45L to 455km.

[ErOR]

I got a app on my phone where I enter details when I fill up like how much/mileage etc so it calcutes all sorts of averages by its self which is neat.

Anyway after about a year of owning a RB25DE R32 it says I get 11.19L/100k.

But dang I find the engine quite hungy once I drive a bit more heavy footed, especially when in a rush.
