Nulon engine oil flush

I used to use oil flush on my old Mitsubishi Colt and N13 Pulsar for every change.
Man, tons of gunk always came out. Made the car run so much better after oil change.
I'm a fan of this stuff on older cars.

Has anyone heard of a Flush additive stuffin up the engine?

I've heard of sludge stuffing up engines if not removed.
Happens all the time on diesels. Man, they sludge up BAD!

ok yes the engine flush could damage the oil filter but u dont need to use it at every oil change. im fussy and change my oil every 5k religiously. only every 10k do i use engine flush to clense the engine.

but as most of you have stated this stuff really works and i would recommend it anyday.

Thanks for all your comments and suggestions! I managed to change the oil(FEO) n filter(OEM). I also used the Nulon oil flush, but only managed to use half of the bottle as it fell on the ground and went to waste. Anyhow, i tried a couple of laps with it and i noticed that the car runs smoother and more eager when revved between 4-6 rpm. Unlike before. My question now is the 10W/30 FEO engine oil too thin for my 96 EK4 with 110,000 kms on it? Should i be using a 10W/40 instead?

10w-30 FEO is fine for an EK4.
