Read up on much fuss about modern diesel being "low-sulphur", mainly to please the tree-swimming dolphin huggers.
The trouble being sulphur acts as a lubricant in your diesel pump & injectors - a deficit of this will cause premature wear & tear to an expensive pump etc...
Was told by a few others adding two-stroke oil at 100to1 (10ml to a litre) to your tank would lube the pump, make the engine a lot smoother/quieter & have other benefits??
Having nothing to loose and a handy unused bottle of Comp2 I dually added said mix to my tank after filling up at the usual filling station. A week later - this afternoon I clicked through the computer menu's to check fuel left.
My average MPG had increased from 68 to 73.2! Hasnt been above 69 since I've had the car??
My mate's went from 23.4 to 27.2 mpg ( Discovery TDV6 )
RESULT.
Try it - nowt to lose...

No harm in it! :)
The increased MPG pays for the oil, less wear and tear is priceless... ;)
Smells nice too. ;D
Can you use it in modernish turbo diesel engines ?

Yep.
My dCi Clio is a 52 plate, running better than ever! 8-)
I used to run an old Peugeot 405 GLD on 50% veg oil in the warmer months without any conversion kit and that ran beautifully ! could you use any 2 stroke oil or is there a specific Make/Type ?
might have to try this one as my car's a soot chucker ;D
Just found this on the net i have a 2003 VW T4 2.5Tdi diesel van think ill give it a go!!! 8-)

Im running Silkolene Comp2, a leftover bottle from my MX days? I would assume most 2-stroke oils would do the job as that is what they are designed to do?
Im thinking the oil helps lube the piston's & cylinder bores causing less friction - hence a smoother more efficient engine?
Tip the oil in before you fill up with diesel - I usually pop 20 litres of diesel in per week, meaning 200ml of 2-stroke goes in. :)
Interestingly in Daddycool's link they have said a vehicle running on a 2-stroke mix runs 50% cleaner than one on just diesel?

No smoke, no poke! :D ;D
Stop's tailgaters. ;)
They are stating 200-1 ratio and that theyve been doing it in the states for some time

gives a nice sense of satisfaction when the car behind is right up your a**e and you dump the throttle to chuck out a smokescreen ;)

I see that? Will save a little oil I suppose? No harm in trying it... also states it will of course save wear in the low pressure pump in the tank? :)
Just read up on EGR valves too my uncle has a diesel passat which seems to be showing signs of a malfunctioning EGR stuttering idle and juddering on acceleration think ill mention it to him as it seems to have beneficial effects on the said valve
Good thread Darren !!! 8-)

Not nice when you're following a smokey old dog on your bike though :o
All these old smokers need is a oil and filter change :)
Cheers for the tip, going to chuck some two stroke oil in next time I put more diesel in the van.
Supposed to stop it smoking so much on a cold start as well
very true, hence it's only allowed with cars ;)

"Exhaust Gas Recirculating valve", links your exhaust manifold to your inlet manifold - under certain conditions it will open to allow burnt exhaust gases back into your engine to improve emissions under say - coasting on a closed throttle...
This to me is bollocks & makes having an exhaust stroke pointless if you are going to let that nasty sooty crap back into your engine??
My EGR is on holiday - have blanked off the hole & relocated the solenoid & shuttle to do its thing somewhere else (if the EGR is unplugged the ECU will freak out)

The ECU is happy the EGR is still connected and working happily, Im happy that my engine is no longer being forced to eat its own ****.
Better cetane rating, also sharper throttle response going from closed to open throttle - does not have to clear its lungs first... ;)
