A mate of mine recently had the donk of his 1994 Toyota Landcruiser pulled down as it had turned over 500,000, plus klms.
The workshop where it was checked out couldn't/wouldn't believe that it had done all those klms, and not been rebuilt.
He told them that both the 90 litre fuel tanks always gets a litre of turps at each refuel.
He said that was why the motor was so clean and wear free.

Graham,
I've heard of dud-diesel being sold off on the cheap & that was found to contain turps. I have no idea what t would do to the internals of a fuel pump (O rings, etc) but I don't think it would be good. Most of the reports on this dud diesel came from vehicles that came to a stop after filling up.
Perhaps your friend's workshop had not worked on diesels before. I have been told that at 400,000 Kms that my Nissan has only just been run in. Changing filters & oils on a regular basis should see diesel engines clocking up many hundreds of thousands of kilometres without any trouble.
I've had gas injection on my last two Patrols - that also keeps the engine clean.

Turps could be a pretty expensive additive for a newer common rail diesel - Just sayin.

Google says it's added to cooking oil to make biodiesel. One thing not mentioned is that there are 2 types of turpentine - the original is called "gum turpentine" which is a clear solvent extracted from the gum of pine trees. The 2nd and more common "turpentine" is a petroleum-based replacement.
Good Luck.

Thanks all. Just wondered. My 1991 Mazda T3500 motorhome has just turned up 300,000. The motor is the Japanese version of a Perkins diesel. Still runs perfectly

Perky says it all.
Plus you can strip and full rebuild the old girls for the price of a set of rings\Shells,
of any other mfg.
I rebuilt the HEAD of my old Yanmar 20 (2 pot) 20 + yrs ago.
At same time I stripped a 3 pot Perky out of mates yacht.
FULL Rebuild kit for that.
Was $3 LESS than the head on my Yanmar cost. to shave. reseat\grind valves.
Replacement Inj, tips and gaskets.
My next donk was a 4 pot Perky (bigger boat) Plus that version of Perky.
IS a Yanmar under licence.
And that was equal to the genuine 3 pot Yanmar to buy.
Yanmar are the best in small marine donk's.

Macka our yachts 3 pot yanmar 38hp is just over 20 years old & the only maintenance costs have been twice yearly oil filter changes.
I have always used Wynns EDT diesel fuel additive & have never changed a fuel filter - don't think I will change to turps & just stick to whisky & red wine for myself

If I was going to play with additive ? I would go the water / meth kits . Either mentholated spirits as in ethanol or methanol? 80/20 mix . Works great on turbo diesels . Keeps combustion chambers clean big time . I have Devels Own kit on our 6.5 non intercooler turbo diesel . It comes on from 5 lb boost so no chance of liquid lock up !!

My old Dad, use to swear by Methylated Spirits
He claimed that there is water sitting above the diesel, which allows bugs to breed, and clog up the filter
He would add it to the tank sparingly, using about two bottles a year

You are absolutely correct, John So thanks for pointing this out
I am not sure if I had made a typo, or just looking at things upside down again
Diesel is lighter than water, and Metho (without the orange juice), is lighter than diesel
It would have been diesel in the tank, with methylated spirits floating on top, perhaps catching the condensation as it entered the tank, as metho is soluble in water
Whatever the process was, my old Dad use to swear by it, perhaps he learned it in his sailor days, as large ships have problems with their fuel filters blocking up, by bugs which live in the water

Metho the better one for catching water\vapour.
I ALWAYS put an cupful in 100ltr boat petrol tank when filling.
Also gives this low octane a boost too,
if you add a tad more.
Rejuvenates Stale petrol too.
Not sure about diesel but I doubt it.
Just for moisture.

There is an LPG add on kit for diesel engines. Doesn't take the place of diesel fuel just augments it, something like 30% improvement in performance from memory.

I was an Engineer at sea in my twenties (General Cargo and Bulk carriers mostly) Although we used to get heavy fuel oil with algae growing in it I never heard of using Meths to clear it. The fuel filters were Delaval Purifier/Centrifuges that are cleaned daily. By me when I was 6th and 5th eng. Just morecrap to scrape off the cones when the algae was bad. We would heat the fuel oil up in the tanks with the tank steam coils on, if it got really bad and jelly like, it is preheated before entering the Purifiers and also before being injected into the main engine cylinders. A lot of ships diesel main engines were "common rail diesels" even 50 years ago.
A 10.000 ton Diesel powered ship I was on might burn an average 2.5 tons of Heavy oil every four hours that would require a fair amount of Methylated Spirits.

Looks like my old Dad, did not lean about metho, when he was on the ships
I know that he did not learn about metho, while eating oranges, as he was never a drinker
To my knowledge others put metho into their diesel tanks, on his recommendations, and never returned to complain

The metho lowers the
viscosity of the water and allows it to pas through the filters.

How does the metho lower the viscosity of water when metho has a higher viscosity? I know that somehow it does but the viscosity bit mystifies me.

I remember something from chemistry along the lines of different surface tensions off liquids can affect mixing. Maybe what it is.
