Diesel oil engine flush?

[badman]

I have been thinking if it would be safe when doin an oil change to refill the bike with deisel oil. To my knowledge it just has a detergent in the oil to clean of the carbon. Would it pick up to much gunk and carbon posibaly blocking a well or damaging something. So would you strongly be against refiling with deisel oil and goin for say a 20km drive before draining it again and refilling with the correct oil?

Why not just use Vegetable oil canola maybe?

seriously tho, why? what are you wanting to achieve here?

[badman]

The goal is to clean as much gunk and stuck on build up out of the motor... Because canola oil isnt made for a combustion engine, nor dose it have the cleaning agent additave that deisel oil has.

In my qualified opinion....don't. With the low viscosity, lack of viscosity and friction modifiers flamibility etc, you run the risk of causing much damage....The only occasions I have done this is when doing an oil change on a very cold marine engine...add about 25% diesel an run for 1/2 a minute, to make the oil runny and easier to pump out.

i'll betcha that 'gunk' is all thats holding yer engine together. better not flush it away

Are you talking diesel (fuel) oil or diesel (lubricating) oil?

If you ran your motor with diesel fuel oil in the sump you would probably find the wearing surfaces of your cam shaft and cam followers in the bottom of your sump pretty dam quickly.
If you ran with diesel lubricating oil, say a low ash mixed fleet lubricant why would you want to drain such a high quality lubricant after only 20 km.

These guys: http://www.therevcounter.com/mechani...ngine-oil.html seem to think you can use diesel oil tl flush the engine - but dont' run the engine, just flush it through.

Note: I am not suggesting you do this - I'm just trying to assist with information.

If you decide to go for it, please let us know what happen....

[LBD]

I will repeat my warning....DO NOT DO THIS....If you think your engine needs a flush/Birthday replace the oil with the correct oil, go for a good run then replace the oil again....although this would not normally be required.

If yo do an oil change on an engine that is cold and has not been started, you can drain the oil, leave the drain plug out, then pour a little diesel in the filler to flush out dregs from the bottom of the sump. Ensure all diesel is drained before replacing plug in sump.

I've used diesel fuel (two or so litres poured over the area needed) to flush crap out of an engine or two (V8) after a manifold swap or similar where debris has fallen into the guts of the motor, then put on new filter and filled with new oil, never had any problems later.

Yeah I realise this, I was taking the piss.
I work for Mobil and they tell us use your intended oil and run for a shorter period flush then use the same oil on top again.

Mobil 1 Racing 4 t for example. He He

Thanks il keep away from the deisel oil. I think il just use an additave from repco then.

I've done a couple of engine oil flushes with diesel fuel and even rode the bike around the front yard somewhat. The engine warmed normally and I could not detect any difference with the engine running on engine oil or diesel fuel (as a lubricant.)

I would strongly suggest you did not open 'er up on the open road doing this. Either only idle it, or else ride it very quietly around the yard, or maybe venture around the block on it. Total engine running time maybe about 20-30 minutes, 3/4 of that time idling in neutral, and the other 1/4 puttering around at very low throttle levels while exercising the gearbox.

I would have no real concerns doing another diesel fuel flush, provided precautions were taken.

Again, there was no detectable complaint, noise, or otherwise, from the engine at any time. The engine sounded just like it had proper oil in it.

edit: dont put any oil additives of any type in motorcycle engine oil.

No no no, leave additives out of it...........sheesh had this discussion on another thread and the idiot did it anyway.
If you are buying a decent oil the additive package is complete, the moment you add a after market additive you will instantly fuck it and the whole oil chemistry
Dont I repeat DONT do this.

And p.s dont flush you engine with Diesel Fuel either ffs

This looks like a fun thread!

Hi. when I was a apprentice back in the early 60's we would flush out car engines with a 50/50 mix of oil and kerosene and then you only brought it up to operating temp at idle and did not rev it at all. Vern
