This is just crazy! Almost everyone says use after run oil. This also applies to cool power synthetic and omega blend What do you guys think?
I cut and pasted this from morgan fuels faq page.
Should I use after-run oil?
No!
Most of our flyers don't use any after-run. Petroleum based !QUOT!after-run!QUOT! oils do not mix with methanol-based fuels. So, we definitely don’t recommend any petroleum based lubes. Our built-in after-run oil is one of the most universally recognized features of our fuels. As an example of this check out these 2 e-mails we received,
This first one is from Troy Davis,
“It has been at least three years since I've flown my model airplane due to the lack of free time so the other day I'm standing in my garage and finally decided to pull it down off the ceiling and see what it was going to take to get it going again… I must admit when I put it away three years ago I did not put after run oil in the engine. The plane went straight from the field, the last time I flew it, to the ceiling. Now the question came to me, do I waste my time with this engine or just get a new one? So I decided to crack it open and check out just how bad it looked inside… So now after I've torn the engine all apart and put it back together I sit here writing this because I just could not believe what I discovered. There was not one bit of corrosion inside that engine. As a matter of fact it looked like it did the last time I pulled it apart when I was religiously flying it every weekend. There was no way this was what I was seeing. How could it hold up that long and not be at least somewhat corroded? Then it came to me as I inspected around in the engine I saw this green oil film all over the inside of the casing. Sure enough the only thing it could be was that all I ever ran in that engine was Cool Power© synthetic fuels... Thank you tons for looking after my equipment for three years while I was unable to tend to it myself.”
And this one from Alan Wellentin,
“I've got a story that demonstrates extreme rust protection. I parked one of my helicopters on the bottom of a pond it stayed the night underwater. The next day when I fished it out, I took out the glow plug, pumped all the water out of the engine, refueled with fresh 30% Cool Power© and started the engine. I let it idle for a tank of fuel then it sat for a month until I got all the parts to rebuild the heli. The engine has run flawlessly. I recently took it apart and the insides still looks new even after sitting underwater for 16 hours.”
Thanks for a great product, Alan Wellentin
