If you have been carrying out routine oil changes with quality oil, then frankly it will serve little purpose, modern oils if used correctly, do not produce sludge, simply ensure that the oil is drained when it is hot, not forgetting to change the filter with a quality OEM type.

A very good point Rev,
This is one of my many questions on my list! On my petrol vehicles ( without and oil cooler or turbo ) I use one every other oil change. I do regular oil and filter changes, so probably not really necessary. But with the 2.0 CDTI in my ZT, is it advisable to put an oil flush in as it stands to reason that even with a full oil and filter change you never get all the oil out? Richard

I used it on the lagoon before I dropped the oil to change the broken sump pan. As the car had a hard life I thought it would be worth it.. when I removed the sump the inside of the engine was like new, no horrible carbon type deposits to be seen anywhere.

Flushing is unnecessary with today's oils, but if there's any good reason to think it's contaminated (like coolant in the sump), then do so.
Flushing oils aren't designed to drive with, so it's a debatable point whether the half litre remnants of a flush are better/worse (for the fresh charge) than the remnants of the old AECA quality oil. I'd say the the old oil is better (and car manfacturers agree.) TC Last edited by T-Cut; 27th September 2019 at 15:32.. |

In my experience flushing oils can often cause problems, engines that were leak free can often start leaking after a flush so unless you know the engine is full of sludge I would not use it.
Good quality oil changed at the recommended intervals or sooner if you wish is all you need to do. On a newly purchased vehicle with an unknown service history it is probably a good idea to do an oil change followed by another a few weeks later. |

What they all said in the posts above,--
For a Diesel example. Took the head off my wife's diesel engine at 200,000 miles as the gasket had given up-----However the inside of the cylinder head, with regular oil changes, looked like new. No sludge, nothing, just shiny clean. |

Hi Jules. I have never used flushing oil and think in 99% of cases it’s a waste of money and time. When I was at work I used to change my oil over the pit in the garage if one was available. I decided at around somewhere in the 90,000 miles with my montego diesel, to take the sump off to clean it out. What a waste of time. It looked like a mirror in there. This was when I ran it on straight 30 grade oil, no multigrade oil ever went in it. So if you want to prove me wrong, take your sump off and waste your time. You know I would not give you any bul. By the way how are you now after the sun in Holland?
