Thread: Diesel Smoke and the D4

I have a d2 update and this feature works well for that as well

Cheers Keith

This is something I have added to the brain bank for when some tool tailgates me next.

A mate who has a D3 petrol wanted to have a drive of my 3.0 D4 today so I followed him driving his F250 7.3Lt TD (with chip, exhaust etc). I did notice that when he gunned it from a round-about there was a puff of smoke but no where near as much as I expected.
FYI: The F250 was a slug in comparison and all over the road. I know its an F-Truck. I have had 3 of them before.
Makes you appreciate the Disco

A F Truck is a slug? Really they have a engine the size of my wifes fiesta..... Strange i also thought they would pull like a train.

The F250 7.3 litre diesel is a pretty old design, designed to run on very dirty US diesel fuel (the US relatively went from having the dirtiest diesel of developed countries to the same high-spec diesel we have here). It is low-revving and low-stress, so it can't be expected to accelerate like the modern 3.0 Tdi D4. I just returned from a trip to the US and suspect that the 7.3 diesel uses a lot of the diesel energy to make rattle noises, and less energy for motive force

The F250 probably has good pulling torque but makes alot of noise and you have to use the pedal to get it moving.
I'll stick with my D4

Thanks for all the comments on this. Have done 4500 km now and have noticed this at night on acceleration from zero or low speed and was wondering if it was just mine.

Speaking of fuel..what is the sticker on the inside of the fuel cap suggesting oil every 1000 km? Can't see anything in the manual about it despite the i symbol.

Actually got a puncture today (around town).
Got out exhaust jack, and then had second thoughts about blocking up the second tailpipe... used the air compressor instead (nearly as quick anyway). Just pulled out the screw which caused the problem, plugged the hole and pumped the tyre back up.

Now I have been driving diesels for over 30 years, but I was still amazed at the amount of carbon junk around the tailpipes, surprised thou that there was virtually none on the bodywork, at least someone in LR got something right
