When doing an oil change should I use an engine flush type additive?

[AllanB]

Actually the car engine flush products smell like kero........

I'd be concerned about running a engine full of a flammable product like kero............

Did the exhaust fumes smell odd?

I'd be concerned about the film strength of kero in a running engine.

anyways just replace the oil

Check out the Q&A on the Mobil web site,,,quite interesting and they recommend you don't bother with a flush.

Goes into some detail about Dino Vs Synthetic.

Doesn't take the burn out of $120 for an oil change though

Engine flush and clutch fibres. Doesn't sound a good idea to me.

Seriously, if you think flushing with diesel oil, kero or any other voodoo shit before an oil change Is a good idea......i think you've got rocks in your head.if it was a good idea, it would be recommended in the manual, there would be brand specific flushing agents (kero labelled "Yamaha flushing fluid") etc.
Running a motor for 20min with kero in it......may make it clean and sparkly, but holy cow.....it's just dumb in my book

I did it before a full tear down and rebuild. Bearings were replaced and entire head was rebuilt. Saved a fuckload of manual cleaning. The engine had 320,000km on it and had a blown headgasket. 100% fixed now apart from one ticking lifter which can barely be heard any way. I would do it again, to the same engine if it was ever needed. It won't though, not for as long as I own it anyway.

I wouldn't trust it in a motorcycle though, unless the clutch was being replaced and most of the engine being torn down and inspected.

You do know there is a difference between diesel oil and kerosene don't you?
As for brand specific flushing agents. They exist. But most people use non-OEM like anything in life. I am yet to see someone use Yamalube in a bike.

Most manuals state to strip and engine though and cleaning manually. But fuck doing that every 40-100,000km.

Ahhhh yeah, I know the difference. If you want to put either in your bike and run it .... Fill ya boots. Same with flushing agents..... Help yourself.
My manual says fuck all about stripping and cleaning, again, you go for it

Latest Repco cattledog has combo Shell oil and some no name oil flush. Don't see Shell oil flush. Why is that? Are they missing a trick? Big oil companies don't know what they're on about?

Or it's bumpkin bollocks.
