Dude, chill out, a little black smoke puff every now and then from the tailpipe is nothing to worry about. It's a diesel engine after all - all diesel engines will make a lil puff every now and then.
Here's the most common scenario's where you'll see your van make a lil' fart:
- cold starting in the morning
- pulling off immediately after a cold start
- using a gear that's too high for your speed
- suddenly accelerating and/or shifting gear (eg. when overtaking a slowpoke on the highway)
- driving under heavy load (eg. plenty stuff in the tray, the van full of fat people, towing a car or other truck, etc. etc.)
- driving up a hill
- hard acceleration (eg. trying to beat that jack@ss in the drop-low civic from the lights)
- air filter dirty
It's only if the black smoke is a constant stream of smoke no matter how or where you drive is when you'll have to worry.
Other than that, don't stress - watch other brand new (TCR/TCS/TCT) pickups and see how their tailpipes fart every now and then, but otherwise under normal driving there's hardly if any smoke at all.
**remember, our diesel is low-grade diesel, not like the good, clean stuff that they have in the UK and Europe. Hence it's expected that our trucks will smoke a bit whenever we fill-up.
also plse explain the metre reading cause one minute it saying 900 and counting then all of a sudden i seeing nothing i seeing like 150 plse explain
Uhh... huh??? What meter you talking about pardna?
and can i use kerosene in my engine ive been reading some say yes some say no
Well, the dealership and most mechanics will say no, don't use it, it'll void your warranty and cause the earth to stop spinning and earthquakes to happen and the zombie apocalypse to come...... but actually yes you can use Kerosene in your engine (since it's a WLT direct-injection engine).
Adding kerosene to your tank serves the purpose of cleaning out the sludge and sediments within the fuel system, from the fuel tank leading up to and including the fuel pump and injectors in the combustion chamber. It's been used before and actually proven effective, once used in a safe ratio (usually 3:1 - diesel : kerosene ratio, or something close to it).
Direct-injection turbo diesel engines are usually less complicated than the newer, common-rail turbo diesel engines with Electronic Control Units (ECU) to control the fuel-regulation, timing, etc. etc. There's usually a LOT more sensors and whatnot involved in a Common Rail engine.
But by adding Kerosene into the mix, which is a lighter fraction of petroleum than diesel, what you're actually doing is unpredictably altering the Cetane Rating (similar to octane in gasoline) of the diesel and thus this can adversely affect the sensors in a computer-controlled system.This will lead to miscalibration of the fuel:air mixture by the ECU, leading to misfiring, pinging/knocking, more smoking in the exhaust and possible engine damage. In a mechanically controlled system, the margin of error is potentially a bit less than with an electronic sensor, since it's simpler, set to operate within a specific paramater and has less sources of error.
At this point in your engine's life, I wouldn't recommend you use kerosene yet, your fuel lines are probably too clean to worry about sludge buildup. Even so, I would recommend you use a fuel treatment like Redline every now and then, or perhaps use Amsoil Diesel Concentrate to keep the deposits in the diesel to a minimum. If you want a little bit more power, you can use Amsoil Cetane boost to increase the cetane rating by up to 7 points and thus help the diesel burn more smoothly and with more power. (kerosene has unpredicatable effects on cetane rating even if you carefully measure how much you put in, but Amsoil cetane boost has a well-calculated amount, plus a graduated bottle so you know exactly how much you're putting in every time).
The fact that you only fill up at Unipet is a great plus, since their double filtration will definitely help keep the diesel in your truck's tank clean, and prolong the life of your fuel-system. You should still change your fuel filter every 20,000km though, and try not to run the van to "E" and let the light come on (don't wanna suck up the dregs in the tank now).....
So relax, chill, it's a diesel you're driving, get used to a lil smoke now and then (i actually prefer the smell of diesel smoke now to that from a gas car).... take care where you fill up, and use the GOOD diesel treatments (Redline, Amsoil, etc). and change your oil & filter RELIGIOUSLY....
I do the same and I plan to keep my Navara till it reach 300,000km+, just like mih daddy ol' L200 K34 turbo (my truck was bought middle of November 2010, and I'm now on 29,885km on the odometer).
would be lucky to do 400km.. and that's on gas eh..
