Yes, do that before oil addative, cleaning out more crud from previous neglect is only good

No, you already did two flushes, no need to do more, engine is the cleanest it can be by now

Engine flush one last time? Or no?
If you have sen my thread, you also know that I have used engine flush 2 times now to clear out crud from previous owners neglect...
Anyways, it is time for me to try oil addatives (liqui moly ceratech and mos2) and my question for you is if you think I should do one last engine flush?

Might be still worth a try if it would give you some more peace of mind.

You could always drain the oil and fill it up with acetone and let it sit for a while. I've done this before on smaller motors. Dissolves carbon pretty well. I don't like running my stuff with engine flush because of the small amount of extra wear it creates.

I just said that because that's what they start with when they are about to wash a junkyard motor to clean it up for a rebuild for high performance applications.

Acetone will dissolve all ABS plastic parts.

I have also heard of people using acetone as a fuel addative to increase mileage, since acetone is very agressive to many plastics and rubber I would never do that
also heard of people using diesel added to engine oil to flush but since we dont have real diesel here that is a no go
coca cola poured into sparkplug holes(gas engine) frozen rusty old engines to make them free up
using brake fluid to remove tint from turn signals(very nice if you get it on the car paint NOT)
some remedies are good but others not

Are you sure people were using Diesel fuel added to the oil? IIRC it's kerosene that's often used for that.

Coca-Cola or anything containing sugar may not be poured into an engine. Some years ago, someone poured sugar in the oil of the engines of trucks and heavy machinery belonging to the local administration of some city in Paraná, as a deliberate act of sabotage. |

I had read an old scientific paper stating that acetone improved mpg by evaporating faster and making smaller droplets of fuel.
Tried it in as 1 small syringe in to 20l gas tank a few times but did not notice a difference. Stopped with fear of melting plastics. The vehicle (2005 bmw r1200gs motorbike, sold to my cousin) still runs great.
