Also went to a Mobil Products book, and they have 3 synthetic oils offered to the aviation industry, all are for turbine, or jet engines. The recip engine oils are all mineral, called the Mobil Aero oils, Numbered Series and Banded Series. Two types, a straight mineral oil and an ashless dispersant oil. Both have military approval.
Are you sure the Mobil problem oil was a synthetic for aircraft recip engines?

YES -it was their attempt at synthetics for the brutal use of aircraft engines. These engines have got it bad. Real bad.
You are the oil expert. I am not. I just recognize things that make me moan. And most of this topic has.
Regarding the Mobil Synthetic AV-1, I'm not going to go dig through 10 years of papers and send you copies of everthing the courts and FAA have had to say about it.
Your right about one thing, Mobil is not currently producing synthetic oil for aviation. For guys who pay $8 a quart anyway and will easily buy the best there is. Mobil mineral oil is all there is. Their synthetic isn't good enough to risk your life in an airplane, but in a car it is the best there is? Maybe so, but Hmmmmmm.
Since I know you prefer a web site as an authority over personal experiance, I did a google search on mobil AV-1 and here are some links you can read.
Rest assured, you won't be reading this stuff on the company web site!

I don't care if you believe me or not. But I hope that some people reading this will see that an oil selection is not cut-and-dry.
I'm not brand loyal and am not qualified to give recommendations, but I'll tell you what I run and you can get an idea of what I believe.
Normal driving - I use generic $0.89 oil that meets the latest codes for new cars. Never racing oil because of the potential of high oil related deposits.
For racing - Mineral Racing oil - such as Valvoline Racing 20w50 - lots of zinc to aid in the brief periods of no oil in long corners and such.
Winter with little use - oil with high anti-corrosives such as a diesel oil - like shell Rotella T 15w40. Sitting is extremely hard on internals as all the shinny metal starts to rust.
Now does anyone seriously know of one oil that does all this?
