Hi Guys, I have heard some mixed reports about this from various indie garages and DIY mechanics. I am considering using engine flush on my Accord Deisel, but will it do more harm than good? (The kind that is added to the oil, idled through, then drained) For example Wynns Engine flush. I know these engines are very sensitive to soot particulates and the like (Cam Chains) and my car has been on the standard 12500 mile service interval so far. So I thought a good flush through may be beneficial. The engine has done around 41k miles. I am intending on bringing the service interval down to 6000 miles (probably 3000 miles for the first one). Would I be better off just running a really short first oil change or trying some flush through? Thoughts and experiences, diesel, petrol or any! Thought it would be good to share with everyone.
