Cleaning your engine with diesel

[Manual Calais]

Somebody told me that you can clean the inside of your motor by replacing your oil with some diesel and running it through for a bit before replacing the oil, is this true and is it a good or bad idea?

[304runner]

Seems like a terrible idea to me.... Maybe just to flush the engine, but not while its running.

If it was good for your engine everyone would be spending $6 on diesel rather the $50 on oil when doing a change.

I just cant see the diesel lubricating the engine enough not to mention the oil pump wondering what the fark is going on....


I say no, but someone else may say different....

I used to know a mechanic who flushed engines with kerosine

The old diesel trick, this is taken out of proportion, they say add a oil lid full, yes hardly anything to an engine 5000 kms before oil change

All adding diesel does is thin the oil. People on here will swear by it (although probably none of them have actually tried it) and there will be people who will say absolutely not. I'm with the nots. There is no real need to "flush" and engine except when changing from mineral oil to full synthetic. Then only use a good engine flush, not diesel or kero or Tibetan yak milk.

The best way to clean an engine and keep it clean is to change the oil regularly. Engine flushes are a gimmick IMO.

LOL @ using Diesel.

[HSV5L]

^ thats for sure

I'm drunk right now, and even so I can't understand how running diesel through your engine can possibly be a good idea. I second Blown V6 Hatch - best way to keep an engine clean is to replace the oil regularly.

Stick the garden hose in it, it works better than diesel.

[monkeys437]

Fill it up with warm soapy water and run it for 5 minutes

Every now and then I drain mine leave oil filter on fill up with cheap oil go for drive drop oil replace filter put good oil in clean as.

I would be more concerned that you think you need to do something like this, what sort of condition is your engine in?

[GRPABT1]

It's an old school trick that is best left in the past. There are products specifically for this these days and they aren't expensive. Don't risk it.

[ari666]

meh, its ok to wash engine parts in. dunno what sort of affect it'd have on the bearing shells though. kero works much better.

pls note i am talking about an engine that has been completely stripped. running it as a lube will result in much lol's for us, so i say: do it and post pics

[Manual Calais]

Um I never said I was going to do it to my engine, I just heard it from someone and wanted to know if it was true, He said he had done it too his and it worked great and i kind of didnt believe him, and when i said run through it i meant idle for a bit, not drive it for weeks, so i guess the answer is no use propper products?..

Bingo is his namo.
