Question about PEA

[buck91]

I asked this in the Gumout Q&A but I'll start a related topic here.

I have been doing a lot of reading about various oil ring sticking/carbon/coking issues and what people are doing to fix them. Seems products used and results are all over the place, from MMO to Seafoam to you-name-it with everything for 100% fixed to hydro locked engines.

Lets not delve into if piston soak is good or bad or better or worse than in the oil or if its "X" amount of oil in "Y" amount of time. Will a PEA type cleaner in engine oil work to dissolve carbonaceous deposits, mostly coking, of rings? It does for valves right? Why would it not for rings? Or is there some fundamental difference I am ignorant of?

A similar question was asked some time ago and the answer is still a no, not for use in engine oil.

PEA is used to enhance combustion and to reduce upper cylinder area deposits.

That's what stood in the air. Why, because of possible seals incompatibility? Molakule, didn't you know several engine oils use PEA already as dispersant and TBN booster? Hunstsmann has specifically engine oil listed in their PEA applicabilities. So they buy a lot, but don't use it?

I did mention that in the thread and your answer to me what: "And your point?..."

Uses: Lubricating oils for engines, to avoid sludge and varnish buildup, corrosion inhibitors. Also used in fuel to act as dispersant and surfactant.

Almost as eclectic as ZDDP, because it has several functions, as detergent, dispersant (the op objectives) and anti-oxidant and TBN booster and corrosion inhibitor ...

Now you came with another (good) one Combustion Enhancer" ... that I never heard of, How come?

You should give a better thought on this matter, Molakule.

There are a myriad of Polyisobutylene (PIB) and PEA chemistries and they are used for various applications.

The type of PEA the OP is speaking about is for use in fuel, not engine oils, and is not recommended for use in engine oils.

A specific type of PEA was used in the dispersant mix in the patent referred to.

And I still don't know what your point might be.

Maybe you could keep things in context, Pontual.

Sure, not to dispense Gummout (fuel treatment) in the sump. I got that, but you are rulling out PEA as dispersant and other functions in engine oils?

Several kinds of PEA were addmitted in engine oils (all kinds of bases) in the patent I brought out. TETA, DETA, TEPA ... all with great results.

I clicked on this thread because I was curious to know what PEA stood for.
