300Tdi Fuel economy ?

[Defender=1st]

Hey everyone just wondering what people are getting out of there 300Tdi's (manual)
i filled up for the first time (only had the car about a week) this week and it took 30 lts and i only did 200kms....15 lts per 100kms :o
i was getting about 9.5 lts per 100kms out of my Td5.
Is this fuel economy normal ?
Cheers Adrian

Deefer 300Tdi - owned 2 weeks (1,300Kms)= 10.82l/100Kms avg

my 200 def gets 10/100ks on bio diesel .goes up to about 13-14 when i slap on my 35s its done 300 000 and still doesnt blow any smoke. how did u get those figures did u run the tank dry or measure the fuel in the tank as when mine says its empty theres still 5-8ltrs left in the tank

Helps having mobilcard :cool: I just enter my odometer reading when filling up and fill all the way to the top. Then when I get my account I enter the data in this:
Car Maintenance Database Software - Computer Log Book - eBay, Home, Hobbies, Software, Computers. (end time 04-Jun-08 10:13:39 AEST) (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&rd=1&item=370056950304&ssPageName=STRK:MEWN:IT&ih=024)
It does both vehicles, averages my consumption :) and cost figures :(

I've been keeping a record of my fuel consumption since buying the Disco over 2 years ago. Without the roof rack, consumption was a consistent 8.2 L/100km. With the roof rack on it averages around 9.5 L/100km.

Between 8.5 and 9.5 l/100km in a Disco.

the way i measured it was i filled the tank, reset the trip counter, did a short trip then refilled...it took 30lts and i only did 200kms

IF your doing over the 100kmph mark then the 300Tdi drinks. But under that as long as your not reving its guts out it should not take more then 10.5 per 100. Is the odometer correct? I know mine is out but I always have the gps. 15 litres is to thirsty.

I've done a fair few K's on the Newell at 110Km/h and haven't noticed much difference in consumption.


15 litres is to thirsty.

Sure is! :eek:

i get low 11's, big roof rack and tweeked

[mcrover]

Mmmmm the never ending question.......

Mine changes with weight, speed, load, wind direction and which way I hold my tongue as well as where I get my fuel from.

My main problem is that normally even after along trip I still drive around for a week around melb so my readings arnt all that good because of that.

BUT in saying that :

- Empty running at 100kms, around......>10ltrs/100kms
- Loaded with gear (normal condition)..>12ltrs/100kms
- Towing, head wind or over 110kmh....Up to 15ltrs/100kms

Another BUT :

- Check the normal stuff, air cleaner etc
- If it is lifted, taller tyres will stuff economy
- Check your valve clearences
- Change the timing belt and make sure it is timed properly and not ever so slightly retarded as this stuffs your economy as well as if it is due for a change it will have stretched and that retards the pump as well.
- Fuel quality plays havoc with economy in all engines

You should be getting better, my first tank full in our Disco I got mid 9's out of but plenty has changed since with both the Disco and fuel quality.

11.5 with roof racks/ladders and loaded with work gear for part of last fill, towing camper trailer for part of and about 200km with roof racks and no ladders. Combination of highway and town

After 400k on original injectors mine still gets 700kms out of 70-72ltrs of fuel. Pat

My wife and I have travelled in excess of 200,000 kms in a defender 300 tdi !!!!! the average would be approximately 12 l/100 km !

[rick130]

11-12.5 l/100km with my work gear + ladders, bar work, etc and 33" muddies on the 130.
Also remember that only those of us running 33.3" tyres have a true odometer (km/100km) reading ;)
7.50/16's and 235/85's make the speedo and odo run 7-8% out, so the mpg's appear better than they actually are......

[naradataranto]

Mate I have 275K on the 300tdi Febder clock and run around on average at 10.5 to 11.5l per hundred.
When I got her some six months ago fuel economy wash trash. Took It to Graheme Cooper Auto in Syd. They did a Full Dyno tune and ended up getting about 3 L per 100 better and 17% better power out of the old girl. I would reccomend a good tune up.

Hell yeah! We get 12.5l/100km towing our 16 foot caravan at 90 km/h :eek:

Disco 300Tdi - owned 3 months (5,000Kms)= 9.12L/100Km avg

Well that figure just went out the window. I just filled the truck after doing alot of heavy uphill towing on this tank:
82.01L for 572Kms = 14.34L/100Km :(

Is your speedo/odo calibrated correctly ?
Non standard sized tyres or gearing can make it inaccurate, and therefore your fuel consumption calcs will also be out.
Best way to check it is to do a run with a GPS. If what you're reading on the speedo is within 5% of the GPS speed reading you should be OK.

Cheers.

My GPS says I'm doing 100Km/h when the speedo is indicating 104-5Km/h. I'm running 245/70 A/T's instead of the standard 235/70's, bog stock suspension and mechanicals. Bullbar, winch and spotties but other than that nothing special done to it.
