    Hi guys,

    Is it okay to use oil flush on an I-DTEC when replacing the oil in a service?
    If so, does it need to be a particular type of flush, or alternatively is there a particular type you must avoid?

    This question may have been covered before, but I've had a good search on "oil flush" in the 8th Generation forum and didn't find any answers.

    I've been careful with my trusted independent garage (Alfa specialist I have used for many years) and for this first service (today) with them I've pointedly asked them to buy the correct low saps oil & to buy an official Honda oil filter (paper cartridge - I must be getting out of touch, I didn't even know these existed!).

    But, they phoned to ask if I was happy to use oil flush on the engine (as I had been very particular in my insistence for the correct parts to be used) - and I didn't know the answer. I've told them its okay to use it today and I'll find out for definite for future services.

    My only mild concern is that there may be some issue relating to the DFP (this is my first car with a DPF), in the same way as the need to use the correct low saps oil.

    Many thanks.

    Personally on neglected petrol & Diesel engine you can use it but on healthy regualrly serviced engines they are not required.

    So its eaier to do early oil change and you will never need to use engine flush. simpler really.

    Personally. I would do an oil change to a quality oil such as the Castrol or Millers, do 200-300 miles then do another oil and filter change.

    The better quality oils have less/no cleaning agent in them so the first flush should see a dirty black oil. After that even after a few thousand miles you should have nice golden fresh oil.

    Thanks guys.
    It sounds like there is no immediate concern regarding using the oil flush, but there are better ways to do it than use these products.
    I think i'll ask them not to use it in the future, the history shows regular oil changes before I got it (on around 78k miles now) & I'm using the SvRS system - so its getting regular oil changes through the Honda dealership & now my local indy.
    Cheers, Mark.

    Just done a 2000k oil change on my bike and the oil is spot on, quick oil changes are a lifesavers for Honda engines.

    I've recently done my 4th oil change on a 6k mile service intervals, so the cars just covered 18k miles at this regime. After the 1st 2 oil changes I didn't notice much difference, the oil still came out black and felt heavy. After the last change 12k - 18k miles service the oil that came out didn't look jet black it still had a slight shine to it and it felt lighter between the fingers like new oil would. So hopefully the regular changes is cleaning the carbon build up out.

    I don't use engine flush as the way I see it is you can't get it all out before putting the new oil in so it will affect the new oil as well. Good quality oil at regular changes should be all you need.

    When I was younger, an engine flush was considered a good thing. In principal, it made some sense. Clear out all the crud and have a nice clean engine.
    Having said that, I didn't flush my cars, as I too didn't like the thought of 'the remainder' left in there either. Better to spend the money on more frequent oil changes.
