Add diesel to oil for change?

Richard 6 April 2005 22:42:00
 Is this okay to do???

Easy Flushes When Changing Oil
Drain out about one quart of oil. Replace that quart of oil with a quart of diesel. Run the engine (in place) for 3 minutes. Do NOT drive the car with the diluted oil in it. The diesel will help clean out passages in the head and will make the oil the thinner, so more comes out quicker when draining, bringing with it any dirt and grime. We have done this on our farm for over 50 years. My dad showed me how to do this growing up, and we now have 260,000 miles on our 94 Ford Crown Victoria with no engine wear (burning oil) and the engine has never been taken apart. Particulates that get trapped in passageways break free sooner or later!

 only problem I have with this is how do you insure that you get all of this thinned out liquid before putting in new oil? Will it dry up before you put in the new oil, or what? Sludge reduction is a good thing but I guess there would be no sludge if oil got changed regularly. (regular oil we're talking here)

I just warm the engine and drain the old stuff when its good and runny then use an extra quart of new oil to wash things out before putting in all new. Just my preference.

just me talking.....

This begs the question: "why?" If regular oil changes are done, modern
engines go 300,000 miles and more. Usually by that time enough other
problems take the car off the road. Even if the flushing extended the life,
in most situations the life would never be used.

Lets see - What are the lubricating properties of diesel? Good luck!

It's actually a fairly good lubricant, but doesn't have the viscosity of
motor oil so won't protect an engine as well under load. I don't see an
issue with doing what the OP suggests (running at idle,) as long as the
engine is in good condition. Of course, if it were in good condition,
you wouldn't be considering flushing it now would you? Catch-22!

It would have to be, considering that high pressure diesel fuel pumps are
lubricated by it!

I usually use something like rislone engine flush every few oil changes
http://www.rislone.­com/products.htm

On occasion, I just add a quart of kerosene instead. Run the engine to get
it warm, add the kerosene and idle for 5 minutes before draining. Be sure to
change the filter. Seems to keep it nicely clean.

And by "modern" you mean 1960 and later. What has really improved are
the oils- you couldn't run a 1966 engine 9000 miles between changes on
1966 motor oil, but you sure can do that with the same engine on modern
oils. And it'll last as long as any 2005 engine given the same care too.

The only thing that should ever be put in the crankcase is OIL, in my
opinion. As a last resort to save a badly sludged engine, I have
carefully flushed the crankcase with kerosene (NOT with the engine
running!), refilled with cheap oil and a new filter, run it for 10
minutes, and then changed the oil and filter and replaced with good oil.
But I'd never do that on an engine that wasn't doomed if I did nothing.

FWIW- the "doomed" engine survived and has run another 30,000 miles or
so and now has 210,000 miles.

 Mentioning "on the farm" does remind me of the things we've done in the past
on my dad, grandpa, and uncles farms. Using kerosene or diesel fuel (either
one) was a regular practice. Running it very long at all really wasn't, but
you can flush out quite bit of varnish, particulates, etc. doing just that.
Combined with regular maintenance, it works out quite well. Running
straight 30 weight for a short time afterwards (50 in big engines) provided
for the removal of what was left (flush and waste product alike.) The
technique is old, tried, and true! AND, recommended by companies such as
Cummins, Detroit, and Volvo in their engines for many years. We ran our
turbo diesels with the governors wide open for years; providing regular
maintenance and flushes as part of this.
On a gasoline engine, it may be better recommended to use something like
mineral oil or a drain through of mineral spirits while the engine is still
warm. Possibly let it run for a couple of minutes. But, be warned!
Passenger vehicle engines are flimsy, when compared to big diesels. Don't
overdo it!

 Really, I'm not suggesting you start it. Just warm it up a little bit
first, then let the thinner/clearer liquid run through it top to bottom and
out of the pan. The straight weight oil then is used as the clean out,
washing away the unwanted fluids and nasty stuff. Running your engine on
anything that can be used to clean paint brushes....yeah, that's obviously
bad. This process dissolves the sludge build up in the lines, heads, and
pan for the most part. Rings, seals, bearings, and high friction zones are
better left alone. And, as for high priced oils (synthetics;) They work
well in pretty much any engine, so long as you have cared for it well before
making the change and have let it break in properly. Otherwise, you may
risk opening up places in you engine for oil to seep through that you never
would of discovered otherwise. (Not a high mileage decision)

 Ahhh - the Chevette...How long before Chevy "re-introduces" that name on a
new line? :)­ As a teen, we used to have a ball with Chevettes. I had one
friend who changed out the engine mounts and put a Buick V-6 in it, Then,
not to be outdone, his friend modified the whole front end (suspension, and
extended it) to accommodate a 350 V-8. The V-6 won in a race as the 350
was just too difficult to control, but it was fun to play around...the good
ol days....
For your Chevette, the dino oils out now are much better then they were> when your car was new.>

 Yeah, I had an 81' Chevette-litte ugly yellow one. Ran the 'living hell'
out of it. Replaced the engine @ 180K miles with a slightly beefed up 2.5
out of a Fiero and an S-10 tranny. Was actually pretty quick. Friend of
mine made use of a 2.8 Fiero GT motor in his and ran some good numbers at
the strip, but I never made it that far.
The good ole days! If only Detroit could make RWD small cars again; how
much fun they would be with an Ecotec!

It's probably okay, but with today's detergent gasolines it provides no
advantage. It's no better or worse than a commercial oil or gasoline
additive, which are also unnecessary.

 I would have to agree with that. And most conventional oils are considered
convential so long as they are a minimum of 70% petroleum based. So, buying
a conventional oil gives you some of the advantages of synthetic anyway(the
main reason they are better than oils of yesteryear.) All in all, with the
2000 mile changes I make with semi-synthetic oils and the high grade fuel I
run, I am probably just as well off as I can get.
