Would adding RL or Gumout to oil have ANY discernible, positive effects for the engine?

Sure would, and nothing good. Stick with engine oil in the crankcase.

I've never seen a real engineering (unbiased, proper) test done to prove it.
One might make an educated guess and think the PEA gets on the cylinder walls; gets hit by hot combustion; flashes off the cyl walls; is exposed to the carbon/gook on the ringpack; cleans anything it touches with gasoline combustion.
Specifically, this Gumout product has PEA and says you CAN use it in the sump's oil.


Recommend only using a product if and only if it says you can on the label. Gasoline additives in gasoline only please, just in case there is a potential chemistry problem in oil.

If your looking into to flushing an engine.... either use a Synthetic or HDEO oil.

99 times out of 100 I trust your educated guess...however, this would be the 1 time I want a second opinion.

EDIT:
Dang, the image did not load until I had typed this.
Good guess.

I modified my answer slightly. I realized the PEA products the OP referred to were gasoline-only additives. Gumout does make a PEA for gas AND oil. Maybe, just maybe, it would do something good. I don't know for sure.

Yes I used the Gumout specified in his picture, for crankcase. Specifically says it. The other Gumout is for fuel system

I heard for PEA to work, it needs to combust with gasoline. Since Gumout PEA Multi in oil does flash off the cylinder walls, it does end up combining with gasoline combustion. ... No engineering studies. I don't really know for sure.

PEA can in part survive combustion to do it's thing.
Porsche (at least used to) recommend no more than 4 PEA treatments per OCI.

So it looks like it CAN get into the sump via blowby gasses...and do something that Porsche doesn't like.

You can also (and people do) put ATF, MMO and STP in the crankcase, but who would??

Now if the Chevron Techron container said one add to the crankcase, that would be something I would want to know more about.

I've seen a tank with techron turn a fresh oil change black. It's doing something...

True, yet the *hope* (trust) is the people of Gumout have put something else in their PEA-based Multi-System treatment to allow safe use in an oil sump directly. (I wouldn't use something intended ONLY for the gas tank.) There is always a suspicion that anything added to the sump, including this, somehow upsets seal conditioning or swelling, or otherwise interferes with all the chemistry in a normal motor oil's additive package. If the Gumout people say its OK to use, trust is what one needs.....

I added 6 ounces of Gumout Multi-System tune up to a 2002 Jeep Wrangler 4.0 that had a good amount of sludge under the valve cover.

I added the 6 ounces to the oil and started the engine. The engine instantly exploded and killed everyone and everything in a 6 mile radius! I am typing this as a ghost and coming to haunt you next!!!

No. Actually I added the 6 ounces of Gumout and drove normally for the last 1,000 miles of the oil change interval. Nothing bad happened, no check engine lights, not even any weird sounds occurred. If anything the little bit of valve train noise this engine has seemed to go away. During the oil change, the oil was very black as usual and nothing else strange happened. Looking under the valve cover with my inspection camera after the oil change, the valve train looked a lot better than before. The thick black sludge that was sitting in the corners and low spots was almost completely gone. Once the engine was refilled with oil and started, the valve train noise did not come back and has not come back yet.

I would say The Gumout Multi-system tune did help clean up the engine more than just a normal oil change alone. I can't report anything bad happening and the Jeep is still running well.

These were my findings and I am happy with the results. Do what you want to do and as always, Your Mileage May Vary.
