There have been several Threads on here about the problems regeneration causes with rising oil levels, a lot of them were written before you join the Forum. If you do a Google search you will find some sorry tales of woe about "regeneration" including a 4 year old Vauxhall Astra 1.9 cdti engine which blew up at 36k miles because the regeneration kept failing until the DPF became so blocked when the regeneration did eventually happen there was so much fuel put into the sump the engine wrote itself off. I have done a bit of research on line and it would appear that the "Super Tech Outboard 2-cycle TC-W3 engine oil" you mentioned in your previous Post is semi or part synthetic oil specifically recommended for water cooled engines i.e. marine outboard engines. It also appears to be thinner than "normal" 2 stroke oils so when used in air cooled engines that run at a higher temperature it can cause premature wear and scuffing on the piston. But we are talking about using 2 stroke oil in a diesel engine, if you are going to put 2 stroke oil into your diesel fuel tank then the advice is only to use 2 stroke mineral oil and to avoid any of the synthetic or semi-synthetic oils. As I said before some of the newer diesel engine have injectors that will clog up if 2 stroke oil is used, if you are in any doubt then don't use it.

Thanks Grant for your detailed reply. I didn't realise the 2 stroke oil used in the US tests wasn't straight mineral oil. However your advice that even mineral oil might clog later types of injectors does worry me. Do you think that the injectors on my MY2012 D5 engine might be vulnerable? Since the engine is a most valuable item, I would not do anything that might compromise it. If I cannot know whether 2 stroke oil would cause damage, I would have to take your advice and steer away from it.

I've had my V70 D5 since about May and I've done about 5000 miles in that time in it!
I asked the previous owner if they'd ever had any DPF issues and he said not but he drove it to Scotland/ and Northumberland a lot so covered good mileage. I had some concerns about buying a car with a DPF as I do a short 9 mile jounrey to work every day and although I go on the motorway it's often stop start in the rush hour. But I also do longer journeys, usually once a week or every other week where I travel an hour or so in each direction and on these drives I tend to give it a boot full every now and again before cruising around 70mph. So far in my first 5000 miles, no issues! Fingers crossed I'm doing it right!

I work in the regulation of the taxi trade and they often fail their test on dpf filters or emissions as they spend all their time tootling around town and never go on a good run. The standard time honoured fix is 2 tins of cleaner in the tank and then blasting it up and down the bypass in third gear. Seems to work well for them. The less scrupulous, particularly with Skoda Octavias, have found a garage that can programme out the dpf so it doesn't show a fault.
