i don\'t think you can mate.

this engine oil flush company doesn\'t recommend (look at bottom of page)

i think that you are asking this as you prolly get some element of black type oil. i always thought thats cos you cant remove the stuff thats left in the oil coolers and thats what darkens fresh oil?

besides rotors dont have sticky valves etc, and theres not much that can get easily clogged.

I have used a FORTE flush before in the past. The good bit is it will break up any sludge and filth in the system and that is a good thing.
However the way these things work is they break down the oil, and as stated above you have a large amount of residual oil in the cooler system when you do an oil change. So this tends to contaminate the new oil and will start to break it down as well. Which is not good for a Rotary. So you have to do a few changes after the flush, usually in the space of a month or so.

Take from that what you will

I\'d avoid it like the plague for the reasons above about residue. If you have to flush, do a few changes in quick successsion with something like Tesco value oil (I\'m not joking) then replace that with the good stuff. If youa re feeling really paranoid then do one more with proper stuff to replace the final bits :)

just a theory but it probably gets past the apex seals. As surggested regular oil changes for a bit also running on v-power will reduce the amount of carbon being produced anyway.
