Hi guys, QUESTION:- 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. Mark.
