Status: offline 		Good catch. I just went and looked at the bottle and you're right. I think they say that cause the fuel is supposed to have the stuff already in it, just like the antifoaming agent. Hopefully it doesn't mean that the after run oil mixed with the new Omega fuel harms the engine.

Status: offline 		That`s my main question as well, Joe. I`ve been using after run oil with my " old " Omega fuel. I`ve sent an e-mail to Morgan asking questions. If I don`t get a response in a couple of days I think it warrants a phone call.

Status: offline 		I recently discovered something very interesting. I purchasd an OS 90 four stroke brand new in the mid 80's. I bench ran it to break it in a few times. Then a few more for kicks. I was a kid, so I wasn't really into caring for the engines very much. The engine sat around after that in the garage, in the house, various places as it was moved through the years. It was in very humid areas, consequently, the outside had some corrosion, the bolts on the outside also had rust. I recently took the engine apart after all these years, and was blown away to find absolutely no rust on the inside! The bearings had varnish on them from the gumming of the fuel and oil left in it, but the cylinder wall, the ring, the piston, the valves, literally looked like new!! I was quite surprised. Leaves me to believe that whatever these fuel manufacturers put in their fuel for rust prevention works very good. I did never put any type of oil in the engine after I ran it whatsoever.

Status: offline 		I would like to see a show of hands of those who actually believe that Morgan (Omega) has
added "ARO" to their fuel, or that it posseses some mystical quality which eliminates the
need for good post-use engine care.

Omega is GREAT fuel. I use lot's of it. I also make a habit of running out the motor at
the end of the day to remove moisture attracting alcohol and then nail the engine with a real
healthy dose of ARO.

Nary a problem. Why should there be?

It's called "MARKETING" and the "DO NOT USE AFTER RUN" is a roundabout way of
promoting their oil package.

Further...fuel manufacturers are reluctant to add anything to the fuel that really doesn't
need to be there. Any additional components mean added cost, added processes and less
burnable mixture....the end result is a product that costs more, and modelers (ARF consumers?) are
notoriously price conscious.

If it ain't nitro (that they can charge a lot for)...they don't want it in there.

Like it or not...That's my take on it.

Status: offline 		I wonder if it's because their Omega fuels all have castor blended with the synthetics which would make an ARO redundant? I'm still waiting for them to get their "FAI" fuel right though

I certainly don't believe they add ARO to their fuel. I'm guessing that they don't think it is needed and might believe it is detrimental in some way....and they don't want to have it blamed on their fuel. I have never heard that ARO was a problem though....but it seems to me that ARO is kinda like a "black art".....people think it does something....but no-one really knows....everyone just has their personal experience.

I'd love to curl up and listen to the stories of why oiling a motor would be detrimental.

Product Marketing is one thing...mechanics are entirely another.

Folks can believe what they want...do what they want to do.

I'll oil my motors thank you all....

Status: offline 		Oiling a motor CAN be detrimental if enough moisture is present when the oil is added. Oil floats on top of water. Mineral oil will not mix with water and the water is traped between the oil and the metal parts. If you store nose down the water will flow toward the bearings. If you add oil right after flying there will be some moisture in the engine. Best to run the engine dry and add castor or even synthetic oil as an afterrun oil. Or at least let it sit with the pistion at BDC for a while before adding the afterrun oil.

I don't know their product --- for all I know some by-product is left over from their fuel which they intend to be useful but under the conditions of some ARO form some reactive product with properties similar to bubble gum.

I sincerely doubt it...but who knows exactly what is in Omega Fuel.

Status: offline 		Oh, and I'm in marketing and if this is marketing....they need to fire their marketing person.

Morgan:

instead of "Do not use after run oils! "

Try:

"After run oils not needed because of the excellent lubricating qualities of this fuel"

No charge...this time.

Status: offline 		Well...in light of the fact that I run out as much of the fuel as I can at the end of the day
and then hand prop it 'til it just won't even try to emit a "pop"....I feel pretty safe that I'm not
storing my engines in an Oil/Water pickling solution.

Others can take whatever approach they want. Mine has proven itself to me to be quite
effective at preventing problems. Period.

I simply don't buy into the "DO NOT USE ARO" thingie on the bottle. Simple.

Why not? How do they know what my ARO consists of? If the fuel has some weird ingredient
that could be corrosive in the presence of some lubes....it's that FUEL that needs to be fixed...

They don't...thats the only reason I can deduce they put it on....to protect them from some frivilious lawsuit....the marketing is too bad to suspect thats the reason.

Most of the warnings on the bottle are for lawsuits. I was reading an old bottle yesterday that I was cleaning out so that I could reuse it to store my homebrew in there that said:

Do Not Resuse this Bottle?

I giggled because I know someone somewhere along the line, cleaned out the bottle and is storing their child's cherry kool-aid in there in their refrigerator.

Status: offline 		Properly taken care of and run dry at the end of a flying session, any engine using a fuel with a considerable castor content will have less of a need for after run oils than an engine running total synthetic lubes or one with wet fuel left in the engine.
Are you going to hurt anything by adding your favorite after run oil (assuming it's appropriate for that type engine)? NO, you will not, just don't hydro lock the engine the next time you go to start it up.

Several fuel companies, including mine, use lubricants that have some anti-corrosion properties in the synthetic. Castor has always been the best corrosion inhibitor for model fuels.

Hope this helps shed some light on the subject.
