Hi:
Thanks for the replies.
I bought this oil at a small airport and was told that it was the only oil that was used in the piston engines that powered small airplanes. I do remember that in Europe, Aeroshell was used by many model Diesel engines.
Motorman: What makes you think that Aeroshell would be a synthetic?
As a youngster, I remember mixing 70 weight oil with kerosene and ether to attempt to run my Deezil engine. No, I never got the Deezil to run! Lol. I bought ether at the local drugstore for 15 cents per ounce with no questions asked. I was 8 years old at the time! Today, I can not buy ether
Stay well my friends,
Frank!
