so i was talking to someone that works at a car shop about the grimy buildup under my valve cover, he told me to drain my oil and leave the oil filter on the car and pour about a gallon of diesel fuel into the oil fill and start the car and left it run for about 5-10 minutes then pull the drain plug back out let the chuky crap drain out, replace the oil filter then fill the car with oil.... and it will clean it all out like new and the car should run better. has anyone heard of this before and if you have done it, does it work well?

thanks guys

 

heeheehee....wait, are you serious?

 

anything i've ever heard about diesel fuel is that it probably shouldnt go into reg. petrol cars.

 

Yes i am serious. i have been told that by 3 different people that it cleans it out so stop laughing....

 

Well my auto shop teacher told us about how his friend at thier shop sold people muffler bearings so maybe its just a joke. But then again you never know. give it a shot and report back

 

Well, there is such thing as a muffler bearing - its just not on the muffler, its on the turn signal apparatus - you know, where you put the blinker fluid

You've been told by 3 different people, huh? well then, it must be true.

go ahead, put diesel in your motor. when you're done, you should replace the pneumatic fluid, too...

this trick really only works under certain circumstances:

1. your car is carburetted
2. your car is really old
3. your car hasn't been maintained properly

 

ok dilbert, i was just saying that 3 people told me, why do you think i put a post on here? maybe to see if its true or not? anyway since you guys are being smart asses insted of just answering the question yes or no, im going to go pout and change my blinker and headlight fluid

Ok. But still, they have oil treatments - why not just use that?????

 

not sure thats just what they told me to use and i thought it might work better than just a treatment because it like breaks it all down and then you drain it all out

 

i have never heard of deisel fuel but i know kerosene works great. i would only use about 1/2 a quart of it though with oil. you can also use ATF at about a 60 /40 mix with oil. its detergents are very strong also.

actually some hondas do have muffler bearings.. there are a couple street bikes that honda makes that switched the exhaust from a 4-1 to a 4-2-1 header flow path depending on the RPM that you are at to atain highest HP. and actaully belive it or not there was a design problem with the bearings , so people would be coming into a honda dealership (that sells bikes) and asking "yeah i need to get a replacement muffler bearing"

interesting,,

 

you know, eventually, this is all going to head towards gay-foam(seafoam).......so, i thought i'd just bring it up.

Personally, i would never ever ever ever put seafoam in my crankcase; however, i would most definately use seafoam before i touched diesel fuel.

 

The only thing I would be concerned about is how well the diesel would lubricate while it was in there. Yeah, it should clean it out and won't combust like gas would. I don't know if I'd want to depend on the lubricity of just strictly fuel though, I would be afraid it would strip the oil off of everything without adding any lubrication, and then you're running metal on metal...

If I did it, I wouldn't run it that long.

Oh - that is an amazing point. Great great point. Great thinking. That is definately something to consider.

though diesel is a really light oil from what i rememer... that is why people can run diesel off of vegtable oil, its just another form of oil.. hell it might work i just don't know if i would trust it.. google it and see what you find.

 

If your trying to clean it, why not just pull the cover and clean it. Or sea foam it. Lots of threads on Seafoam.

 

Yeah.. there's nothing wrong with Seafoam.. i used it.. and so did my friend with an SH and it worked great.. The only thing it wouldnt work on is that if your car's really really old.. we tried it on my friend's 86 porche and it didnt turn out very well LOL.. thats just because his car's old and all that **** in his engine was too much..

 

ive heard of the diesel trick, except defently not a gallon of it, but a syrofome cups worth, and u dont drain ur oil, u mix it with the oil and let it run for about 10 mins and then do an oil change..... my automotive teacher does this once a year, and after inspection of the engine it does clean up a lot of stuff.... but please seriously, not a gallon... one cup

 

That procedure would probably clean some stuff out, but it is so thin I would be worried about bearing dammage. You would definitely not want to load the engine more than just idling it if you try this. IMO, I wouldn't worry too much about oil varnish inside the engine. Just switching to synthetic oil may clean out things pretty good.

 

ok you guys from what i know diesel gas will NOT work in a regular car. For one thing diesel gas doesnt work w/ sparks, it compresses the gas in the cylinder to the point where it is dense/ hot enough to ignite on it's own while our cars compress the gas then uses sparks to ignite the gas.

second of all my aunt who doesnt know anything aobut cars borrowed my uncle's expensive car and she decided to put in the most expensive gas in the expensive car. Guess what guys? The car didnt run anymore! yay for diesel!!! lol well anyways that's what i heard.

 

its true if you put diesel into the engine it will clean the engine from inside

kerosene is just dirty uncleaned diesel nothing else

Did you not read it??? he wasnt asking if he can use diesel in his premium unleaded buring car... he was asking if putting DIESEL IN THE OIL will remove sludge from the engine

 

Why are you guys being such fucktards? Yes diesel works, but don't use a goddamn gallon of it. Drain about a pint to a quart of oil out, then replace the drain plug. Next add about as much diesel as the oil you drained out. Run the car for about 10 minutes or so. Don't drive it, just let it idle and rev it a few times to get things churned up (rev to like 2-3k, don't hit redline or anything crazy). But I mean, if you're going to only do it once you might as well just buy the store bought engine cleaner, instead of using diesel.

This does work, and essentially it's pretty much exactly what the engine treatments you buy at the store are, and it does the same thing. The only reason people use diesel is because it's wayyyy cheaper for the amount you need and if you're running a buisiness it can save a lot of money.

 

So the process would be:

Drain a quart or so of oil
Add a quart or so of diesel fuel
Run engine for 10-15minutes
change oil completely - along with oil filter
..........???????

And everything's supposed to be "clean" right?
