Are Rolling Coal utes starting to appear here in Australia or is it something else causing the black exhaust smoke.
Tuesday as we were coming into Mackay on the Peak Downs Hwy near the Racecourse Sugar Mill, I was behind a great looking tricked up 79er, for the next 3 sets of traffic lights it excellerated hard, emitting huge clouds of black smoke from the exhaust.
Later in the day another flash 79er appears to be a rolling coal as we headed out on the Bruce Highway north towards the Leap.
Rolling coal is definitely a thing here in Oz, especially out in the mining districts in Central QLD. Had a it a fair bit whilst doing cycle touring out there, especially after knock off time. They really enjoy doing it to cyclists.
Hi oldbloke,
A 79 series is a Toyota Landcruiser.
The 79 series has virtually the same V8 as the 200 series but the 79 has a single turbo and the 200 has a twin turbo.
I have a mate with a 2014 model 200 and his can blow black smoke when he puts his boot into it but he has worked out to drive it manually.
He says he stays in 3rd and 4th around town and 4th up to 80 kph and then uses 5th. He recons if he stays out of 6th the motor runs sweeter and he actually uses less fuel than if he uses 6th
He recons in 6th the motor lugs along at a very low revs and the fuel is not being burned.
This could be right, I dont know but it sounds reasonable to me.
Those Nissans were a known rolling coaler. They all did it.
About 7 years ago I had a Patrol that would blot out sunlight when you put your foot down. Mine was a ute but those wagons were observed doing it as well.
I do see that some Toyotas are doing it when accelerating hard.

There are many who believe that driving in as high a gear as possible is a good thing to do,and that because the revs are lower,the car will use less fuel,but this is incorrect. Keeping the revs up results in the engine running cooler,with lower water temps,lower oil temps,lower engine temp,better air circulatiin and better fuel economy because the engine is working more efficiently,keeping it clean.Your friend may have researched this,or he may have stumbled on the result by experiment,but either way he is correct.With my little V8 I change gear at 3000rpm and never let the revs get below about 1600rpm,but I still manage to get 5.8km/litre (17 litres/100km+/-) while running at 6800kg GCM.Nothing like having a bit of V8 grunt! Cheers
P.S NEVER a sign of any smoke because I have had the engine tuned by one of the best in the business.Cost big dollars,but well worth it!

Still didnt answer the question. If you were rolling coal with a standard engine, there was definitely something wrong.

Either your tune or your driving style.
Sorry rgren2 but I didnt make the statement you quoted originally. All I mentioned that I had a Patrol that would blow black smoke.
The motor was a diesel but A motor is A motor to me. If it starts and runs then all is good.
The Nissan I had was gutless but reliable. I was warned off the newer Nissan Patrols as the motors could blow pistons according to a mechanic who services them. These werent the newest models but those ones with a smaller diesel. I think they were about 3 litre.
Due to my requirements and finances at the time I bought a Triton which doesnt seem to blow black smoke and is still going strong.
When I got crook I sold the van I had. The triton served me well towing that unit.
Maybe Clarky1 could identify those Nissan engines that were all guilty of being smokers.

Good point. I wait with anticipation for his reply.

It is not only my observation that is reporting this situation but here is a Google search link to plenty of reading on the problem. 10 pages of links.
If that vehicle in you avatar is your current vehicle you might want to be aware that some of those models can have trouble not so much with blowing black smoke but blowing pistons. This can result in big dollars for unsuspecting owners.
Making broad sweeping statements about a brand, not any particular model or engine is just ignorance. If exploroz is your only reference you will need to expand your reading. Yes, the 3L DI did have an early problem for some vehicles, but not all. The DI was replaced in 2007 by the CRD, mine is a 2008 model. I can assure you that it does not roll coal. I did get booked once in my Toyota Hilux in Sydney for excessive smoke, which was understandable as I was taking off from a set of traffic lights up a steep hill and the 2.2L diesel was not noted for its power, that required me to reduce the fuel further reducing power. I was very happy to see the last of that vehicle in the dealers yard.

The reference I made to blowing black smoke was my observation.
Craig1 and Brodie Allen made mention of a similar observation, maybe you might question them as well or maybe they might like to comment further.
Thanks for putting this up Stu.It is common knowledge that the 3 litre Nissan diesel was a dud,not only blowing pistons but being gutless from day one.Bad move dropping the 4.2 litre motor,probably among the best motors ever built.Now you can instead buy a 400hp V8 petrol powered model, and tow your own fuel tanker.Beautiful machine,looks good,well built,with abundant power.My neighbour bought one brand new,and several months later towed a nicely set up camper trailer to Cameron Corner and back.Almost had to sell his house to zero the credit card.Cheers
Just simple observation from me and the cook. We see a Nissan around town and 9 times out of ten she blows the smoke. But I owned a Nissan MQ (1984) and it also choofed plenty in early 90's. A 3,3litre old style diesel, so not much changed.
My lawn mower man had the 4.2litre turbo Patrol Wagon, it had a big haemorage and blew white smoke.
I think you hit the nail on the head Derek. All comments mechanical as discussed above should be prefaced by the vehicle service history and any modifications.
