I use Morris XHD "ringfree" diesel oil. Good spec. oil sensible price too.

I also run my `bike on it ! 1200cc Aircooled, 125BHP, if it`s good in that, it`s good in anything

i wouldnt worry about it too much, its an industrial diesel motor. any well known brand will suffice, i use that texaco stuff (i think) £8 from morrisons.

If it was a petrol engine you'd have 30 odd posts by now!

If the oil meets vw's spec for turbo diesels then it should be good enough the most important thing is to change it frequently at least every 5000 miles

yes, and i reckon every oil on sale in 2007 will meet 1980s oil specifications. unless its for sale on a car boot in romania, where they blend it round the back using goats nostril juice.

We had a Lubrication Survey on our mobile quarry plant (a few years ago) The company came back recommending all sorts of weird and wonderfull oils for our aged diesel powered plant. When we pointed out the whole lot had been running on Shell Rimula 15/40 diesel engine oil for donkeys years they revised the report to say "We recommend you carry on using Shell Rimula 15/40"

I use Rimula Super 15/40 in our petrol / LPG powered van. The spec far exceeds anything the petrol engine oil comes up with, and it sure as hell don't need super synthetic in it !

BTW an oil specialist told me recently that the Rimula diesel oil also resists the breakdown of the oil that gas seems to cause

Shell Rimula 15/40 - thats a detergent oil is'nt it? Great if you have been using it since new, disaster if you put it into an engine which has never seen a strong detergent oil. Washes all of the carbon out of the ring grooves etc and it will instantly start to smoke and use oil like no tomorrow. Great oil agreed but not in older engines unless they have grown up on the stuff.

isnt that what we want ? carbon free combustion chambers, clean running. a tage 1 tune is only a good polish of the ports, piston head and head.

all the gum and carbon helps to seal the engine had customers who would use a oil flush in there cvh engines they would then smoke like hell

Exactly as Diviy said. If you buy a brand new engine then yes use a detergent oil or use an engine flushing oil during your regular service. But if you have an older higher mileage engine, the for goodness sake don't start to use it.

Engine need to grow up on these oils. Yes a Carbon free engine is better but if its built up carbon then leave it there is helps seal things to. Carbon is a good lubricant also as well as a great packing material around rings etc.

If you do decide to use a Detergent Oil, you will need to carry out oil filter changes at every service as the carbon will block the filter and possibly more oil changes.

Plant machines have massive filters partly due to this, as well as the fact these engines tend to be massive.

An oil filter wont necessarily pick up the fine carbon in your oil and it will tend to stay in suspension within the oil - but don't worry carbon is a great lubricant too.

Some - or probably most modern diesel engines have internal centrifuges to remove the very fine carbon from the oil in addition to the filter.

Also removing it makes the oil last longer.
