Years ago when our engine oil got very dirty, we would drain out the
dirty oil, then add two quarts of kerosene and 2 quarts of clean oil
and run the engine for 15 minutes. Then drain out the dirty mixture
and then add new fresh oil. The oil would then remain clean for the
longest time. I have one hydraulic valve that must be hanging up and
want to try this to see if I can free it up. The tappet is very noisey
when the engine is cold but then quiets when it warms up.
The engine is a V6 Buick Century. Anyone have recommendations or agree
with this old practice???

good chance that will ruin the engine...

change oil, add slick 50 its a super lubricant, and may help.

oil additives are worlds better than years ago, and engines dont get
as dirty inside, unless you go way too long between oil changes.

but no oil cleaner or additive will fix a worn out part like a worn
out cam lobe......

I wouldn't do it on an engine that I really cared about, but I think it
has a good chance of working. Sounds like a sticky hydraulic lifter and
that's the kind of thing that a good flush can rectify. Might want to
try something like Auto-RX on an otherwise good engine though. No
personal experience but it sounds like one of the few additive/flush
products that doesn't make the guys at BITOG shudder in horror.

If the lifter is sticky you can buy Rislone or Marvel Mystery oil, or

If the cam lobe is worn it won't fix it, but usually a worn lobe does
NOT quiet down when it warms up.

What it claims to do. Slick 50 is a Teflon suspension which claims to
coat/impregnate the metal parts with a friction reducer. The
manufacturer of Teflon, DuPont, says their product MUST NOT be used in
an engine. I've tried the stuff and found no increase in fuel mileage
over the duration of the test and only minor reduction in operating
temperatures. A total waste of money. Their FUEL SYSTEM product
Synchron,works about as well as MMO when used in the fuel system.
However, they call it an "8,000 km" fuel treetment, making it sound
like there is some residual action. All it really means is if you use
it every 8000 km you will keep engine combustion chamber deposits in
check.
Rislone and MMO are simply solvents/detergents/oxidation inhibitors to
reduce the viscosity of the oil when cold,disolve gums and carbon
deposits, and help prevent further deposit formation. When used as
directed they do EXACTLY what they claim to do. By removing deposits
that cause rings to stick they will reduce oil consumption and improve
compression if sticky rings are the problem. By removing gum from
lifters they will quiet noisy engines if sticky/dirty lifters are the
problem. By removing deposits from oil galeries, rocker shafts, etc
they will improve lubrication to the valve train, reducing wear and
noise - if reduced oil flow due to deposit buildup is the problem.

Now, the thing is, with extended drain intervals on hot-running highly
stressed engines deposit buildup IS a known and well documented
problem - and removing the offending deposits WILL improve the
performance, sound, and life of the engine. These are 2 products that
when used as directed WILL do what they claim.
I've used both over 40 years with very good results. MMO added to an
aircraft engine that had sat for a few years and had
compression/leakdown test results that indicated the engine should NOT
fly came back up to PERFECT readings within less than 20 minutes of
ground run-up.
Added to the fuel it also helps remove/reduce lead buildup on valve
stems of engines like the older Continental 85 HP that were designed
to run on 87 octane avgas (which had less lead than today's LL100
which is about the only "avgas" you can buy most places today)which
causes "morning sickness" - or sticking valves when the engine is
first started.

I don't know what's "possible" but when Slick 50 first hit the market
I saw a lawnmower engine supposedly treated with it run for about an
hour with no oil in the crankcase. It had supposedly been running all
day every day the previous week.

A couple years later I dumped some in my '81 Olds-88/350 beater and
didn't change the oil for about a year.

In -30 temps that was the only car on the block that would start, and
I mean two pumps of the throttle hit the key and vroom.

I parked that thing for almost 3 years before giving it to an out-of-
work neighbor with 5 kids that had his wife and month old infant
killed in a head-on in their only vehicle.

Threw a new battery in it and, vroom.

I've used kerosene to flush a lifter older hydraulic; as you
suggest, NOT the same approach.

When a quart low on oil, just add less than a quart of kerosene to an
already warm engine. Drive it for a short rode trip and then change
the oil. If it works, and cleans any *speck of sand* out of the lifter
it will be noticed. Any worn parts will still be noticed as damaged
and needs repair.

The Marvel Mystery Oil suggested it a good idea, imho.

I've also used Auto Transmission fluid in fuel systems. A full tank of
fuel and one quart to ATF in the tank. It cleans the system, carb and
removes moisture. Granted these were older vehicles... Also have added
ATF to engine oil as mentioned above. Many oils have had detergents in
them.

It is an old practice, but they worked...

I recall State Fair(s), that had a 6 Cyl. engine running for hours on

Well, yeah, that was the point - that the FTC didn't believe that it did
any of that stuff (and DuPont was a little unhappy about non-approved
uses of PTFE)

http://skepdic.com/slick50.html

I believe that at some point they had to stop using the word Teflon in
their ads even though they correctly labeled it as a DuPont trademark
when DuPont told them to knock it the hell off. I think at one point
DuPont was trying to forbid the sale of PTFE to the makers of Slick 50
because they so vehemently opposed its use in oil additives. My memory
may be faulty however so best to try to verify all this.

Here's a page with lots of info on other legal shenanigans related to
oil additives:

I don't know what's "possible" but when Slick 50 first hit the market
I saw a lawnmower engine supposedly treated with it run for about an
hour with no oil in the crankcase. It had supposedly been running all
day every day the previous week.

A couple years later I dumped some in my '81 Olds-88/350 beater and
didn't change the oil for about a year.

In -30 temps that was the only car on the block that would start, and
I mean two pumps of the throttle hit the key and vroom.

I parked that thing for almost 3 years before giving it to an out-of-
work neighbor with 5 kids that had his wife and month old infant
killed in a head-on in their only vehicle.

Threw a new battery in it and, vroom.

ANd who's to say it would not have done the same without.

As for the "no oil engine" demonstration, that has also been called
into question by the FTC if I remember correctly - and I have seen
engines idle for hours without oil.With NO slick 50 or other snake oil
added.

good chance that will ruin the engine...

change oil, add slick 50 its a super lubricant, and may help.

Don't waste your money on snake oil.

oil additives are worlds better than years ago, and engines dont get
as dirty inside, unless you go way too long between oil changes.

but no oil cleaner or additive will fix a worn out part like a worn
out cam lobe......

best wishes

If the lifter is sticky you can buy Rislone or Marvel Mystery oil, or
you can use kerosene.
If the cam lobe is worn it won't fix it, but usually a worn lobe does
NOT quiet down when it warms up.

What makes Slick 50 'snake oil' and Marvel Mystery Oil and Rislone not? Not
a flame. I just want to know.

What it claims to do. Slick 50 is a Teflon suspension which claims to
coat/impregnate the metal parts with a friction reducer. The
manufacturer of Teflon, DuPont, says their product MUST NOT be used in
an engine. I've tried the stuff and found no increase in fuel mileage
over the duration of the test and only minor reduction in operating
temperatures. A total waste of money. Their FUEL SYSTEM product
Synchron,works about as well as MMO when used in the fuel system.
However, they call it an "8,000 km" fuel treetment, making it sound
like there is some residual action. All it really means is if you use
it every 8000 km you will keep engine combustion chamber deposits in
check.
Rislone and MMO are simply solvents/detergents/oxidation inhibitors to
reduce the viscosity of the oil when cold,disolve gums and carbon
deposits, and help prevent further deposit formation. When used as
directed they do EXACTLY what they claim to do. By removing deposits
that cause rings to stick they will reduce oil consumption and improve
compression if sticky rings are the problem. By removing gum from
lifters they will quiet noisy engines if sticky/dirty lifters are the
problem. By removing deposits from oil galeries, rocker shafts, etc
they will improve lubrication to the valve train, reducing wear and
noise - if reduced oil flow due to deposit buildup is the problem.

Now, the thing is, with extended drain intervals on hot-running highly
stressed engines deposit buildup IS a known and well documented
problem - and removing the offending deposits WILL improve the
performance, sound, and life of the engine. These are 2 products that
when used as directed WILL do what they claim.
I've used both over 40 years with very good results. MMO added to an
aircraft engine that had sat for a few years and had
compression/leakdown test results that indicated the engine should NOT
fly came back up to PERFECT readings within less than 20 minutes of
ground run-up.

How do you know it wouldn't have come back to perfect readings without
the MMO if you had simply changed the oil and run it for 20 minutes?


Because we tried it - a couple times. Owner of the engine was just
about ready to tear it down for a rebuild when I suggested the MMO. I
had a bottle in the truck, and 20 minutes later, it was fixed.
Added to the fuel it also helps remove/reduce lead buildup on valve
stems of engines like the older Continental 85 HP that were designed
to run on 87 octane avgas (which had less lead than today's LL100
which is about the only "avgas" you can buy most places today)which
causes "morning sickness" - or sticking valves when the engine is
first started.

Thanks for the reply. So often people don't have that kind of basis
for their claims and then they get really mad because the question is
asked.
