Review: Best engine cleaner - Used this on my high mile dirty diesel and cleaned the engine like new, the new oil stayed clean for several hundred miles after
Review: Seems incredibly efficient at sludge removal - Okay, for background, I've got an old, high-mileage petrol car that hasn't seen a lot of love over it's life. That changed almost two years ago when I bought it and restored it. Bear in mind I'd done an oil and filter change just a year before this experiment. So, last summer, I carried out my second service on it, and oil is obviously going to be the core of that service. I did as instructed, and added this to the existing oil (hot) then let it run for the prescribed time. I had noticed the camshaft visible from the oil port was pretty black in places, and amber in others. I drained the old oil. It was black and dirty as expected - I only do about 3000 miles per year, mostly short trips, meaning frequent oil changes are even more important. I changed the oil filter and refilled the engine with some Comma 5W40 fully synthetic oil, then let it run and heat right up for 45 minutes. I then dropped that oil. It was utterly filthy. I pulled the new filter out, and it too was really nasty. I let the engine sit and drain for ages, until cool. I put in another new oil filter, and went to put in the final oil. I noticed the crankshaft was clean, free of black sludge and *almost* all the amber colour had gone. It was a serious difference, one which I hope had taken place throughout the engine. I filled up with Castrol Edge 5W40, and it's been smooth running ever since. I'll definitely be using this again. Yes, the way I'm doing it is expensive, but it's getting an old engine clean and keeping it up and running nicely. Good oil is the lifeblood of any engine. I do believe that this product, used in the way I've described, will keep that oil flowing everywhere, and allow it to maximise protection.
