High fuel consumption

Forgot to add my cocky mate reckons you never get the same economy out of winter diesel mix, not sure if you would be on winter mix down their or not .
Cheers Pete

Good ay Pete, hows things ?? Yeah Im putting it down to cold starts and extremely short runs while its been so cold, I spoke to my mechanic mate tonight about it and he reckons the same thing. He said they will pump in more fuel and obviously been so cold in the mornings he said will pump more in obviously taking longer to warm up. Yeah Im a bit dubious about these D4D's about picking up crappy fuel and costing a whole heap to repair, I was watching ation 4x4 dvd and they had a 200 series on there that had picked up crappy fuel and stuffed all 8 injectors and pump repair I think they said was about 18g's scary stuff but apparantly the servo company admitted to the bad fuel, but could have been a costly thing if he hadnt kept the receipt, I always end up with a console full of fuel receipts just in case. I would love to drive a 1kz with a dp chip to see the difference, I want to get one but for $1500 is alot if it doesnt make the difference they say, suppose to be from 343nm's to 398nm fair difference and virtually no difference in economy ?? Am going to ring them and see wether if I fit one and not happy with it within say a 30 day period I get my money back ??? There are a few areas (lon hills ) etc and know how it normally goes, eg pulling up mooney mooney Im normally out of over drive foot down pulling 110 up the hills, this can change slightly depending on weather conditions etc but have been told it will pull up without dropping from overdrive obviously under the samde conditions. I dont believe we run winter diesel here in our area ?? Not 100% sure on that, I thought it was only alpine areas. Regards Steve M

Hi Greg, they probably do but I think my main issue is the cold starts and so many of them lately. I did a run a while back (summer) all freeway driving and it jumped to 13.3L per 100 (more then the old V6 12.2) and was told by a few people that it was due to the rain and extremely high humidity) had moisture all around the aircon vents it was that muggy, one of those days when it was 30+ then poured down rain but was really muggy as well and still warm, mechanic told me it drank more as the air was so thick ?? Made sense I suppose as I have driven the same drive again a few times and it dropped back to normal. I did go to Woolongong the other night and it did 11.1L per 100 and I dont baby it. I will see how it goes over the next couple of weeks and if still up there I will get it checked out, maybe an injector/s issue although I dont think so. I thought been computer controlled it would work itself out in regards to dense air etc, dont know, it seems to be running fine other wise. Regards Steve M

Hi there Barry, I dont sit their warming it up once started but I do only idle away and fairly easy on the throttle till I see the temp guage move a tad, I dont like to flog it or accelerate hard till it warms up, I pretty much crawl around sort of not over 40k till it warms a tad by then I have come too the main road which requires a bit of right foot to blend with the flowing traffic. I have been told this is better for the turbo till it warms a bit ?? I change oil filter and oil every 5k without fail. I'm pretty sure its due to the excess start stopping I have done the last week, running wife to doctors (5k away) then to Penrith 8k from home then back to doctors with results and things, then to local shops, back home, pick up 2 year old from daycare everything with in 10k radius. Regards Steve M

Barry, If you where down here at the moment you might change your mind about that lol.
The max in Bathurst today was 6c. My northern friends think freezing is below 20c lol.
Cheers Pete

Hi Steve

what you are doing seems OK as I do similar but a bit over 40. It's not just the turbo that likes a light load until at operating temp,,, most mechanical things do especially drive train components incl g/box and wheel bearings etc.

Pete

yep we had 2 winters down South last 2 years and it was a shock after 25 years in the tropics. Still belive in start up and drive off slowly with light load.
