Thanks for the Birthday wishes.
I am NOT recommending this process only saying it has worked for me and this will be the fourth time I've done it.
Allow the old engine oil to drain hot ideally overnight so that most of the stuff comes out of the engine. It will still show the occasional drip of old oil even after having the drain plug removed for over twelve hours. Then put the DIESEL FUEL in the Engine. Don't forget to replace the Oil Sump Drain Plug....
Yes, then drive the car very gently for five six miles. That should be enough to get it up to normal operating temperature. Don't drive silly. No more than 3000-4000 rpm and then only briefly. Then immediately drain it hot. Allow to drain for at least and hour to get 99% out of the engine. You be surprised what that Diesel Fuel will shift. This image shows what the DIESEL FUEL looked like when it went into the engine in the tray on the left, and what it looked like when drained hot after that six mile gentle run.
Note what remains in the Bowl after draining the Diesel Fuel ready for disposal at the local council recycling depot. That harmful muck would remain circulating in the engine without the treatment. :~
What particularly impresses me is the condition of the correct 10-40 Semi-Synthetic after the Diesel Fuel treatment. Even after several hundred miles later, the 10-40 S-S Oil is still clean and clear on the Dipstick.
Over on other car sites I visit, apparently many engines now do NOT have an Oil sump drain plug! Come oil change time, old oil is sucked out of the engine. Yeah ... right.
The first time I tried this was on my first MG ZT 1.8T project three years ago. Bought with suspect so called Cylinder Head Gasket Failure and non-runner owing to FFS. The signs were there with initial checks. Like this :~
With further confirmation. I want all that muck O_U_T!
Three years on, I use that car as a daily driver and it runs like a turbine. Performs impressively and being the first 1.8T ZT I ever drove, I was surprised how well that little power unit copes in such a big car. I love the 1.8 Turbo K-Series. This is the fourth one I've rescued. One of those four has a successful low mileage MG6 engine transplant.
Over on the 75/ZT Club sight, strong opinions suggest the 1.8T is the best engine in the 75/ZT. Yes, better than the KV6s and BMW Diesel versions. The V8 does not count I guess. I found that hard to believe when I first read that. Now I understand what they mean although all engines have their attractions.
The only disadvantage with the 1.8T is the silly high and unfair UK's VED @ about £275 per annum last time I looked. That thanks to the EU's erroneous Emissions Guidelines which dealt Petrol engines an unfair penalty. Those VED values calculated on the wrong parameters and actual harmful stuff measured. Correction, NOT measured. Our previous Governments eager to be seen to be doing the right "green thing" back then, used those falsehoods without question. Plonkers! Glad that's been found out for what it is but, still nothing done to redress that unfairness.
How come I'm awake at this hour? Can't sleep. Something I usually do with ease. That chest infection is starting to clear and if I lay down to sleep, I soon start coughing painfully. If I sit up, no coughing or sneezing. There's a lot of this about according to a news item on the radio today. One or two news correspondents struggling to speak due to chest/throat infections. I know how they feel.
I shall try and sleep sitting upright in a chair. I may just fall asleep from exhaustion anyway!
