LEADED vs UNLEADED

Hahahaha, sorry about that. :laughing:

Back in the 80's when I was working at the airport, the Confederate Airforce (now the Commemorative Airforce) brought in their B-29 FIFI and stayed here for about a month. They were doing rides and promotions in the area, and yes, they sucked down many, many gallons of gas while they were here. As I recall, we only had a 350 gallon truck for gas. So many trips to the fuel farm, too.

The Super Connie is still one of the most beautiful planes ever built! :thumbsup:

Since 115/145 has not been available for quite a while, I assume that the Commemorative Airforce is now using 100/130, thus having derated power.

I have no idea, as I haven't been involved in aviation since 1986. I've read that it is available at places like the Reno air races and such, and it is still made in special runs, for special orders.... isn't that special? hahahha. It would be interesting to see what fuels they use when they travel around the country in planes with engines spec'd for that fuel.

Some time back we had a petroleum engineer that posted and answered questions.
He agreed with me that using diesel oil in gas engines was a bonus due to the additives contained therein, more lubricants in the composition .

Last time I used/burned any 115/145 was in 1967

The very first day I worked at an airport, it was an airshow! Lots of warbirds and vintage aircraft. Our fixed gas pumps had 80, 100, 100LL and jet fuel. They brought in a truckload of 115. I distinctly remember red, blue, green, purple gas. This was 1979.

I switched to a different airport in 1980. We had no fixed pumps, just trucks. We had 100LL and jet fuel. That's it. When we had airshows, they'd bring in 115 as I recall. That was 1980-1986. Only two airshows as I recall.

I do miss working those airshows. The pilots were always nice and friendly and would show you everything about their planes if you asked. :thumbsup:

Leaded gas was not to help with valve wear. Old mechanics lie. It was ENTIRELY USES TO INCREASE OCTANE at a cheaper cost than refining. Use premium if you need 93 octane. Forget wear enhancements. Its baloney

Ah... the "Connie" ..... in my opinion, the most beautiful transport type airplane ever built.

My first plane flight was on a Connie in my youth.
Air Canada's Connies were rigged for long trips and the seating was like on a RR sleeper car.
2 seats facing each other and convertible to sleeping bunks.
In the tail section they had a lounge area with a center table. You could almost get sea sick back in that lounge as it wiggled from side to side.

"Air Canada's Connies were rigged for long trips"..

Not Air Canada...but U.S. Navy... I spent 16+45 flying a Connie.

Would love to hear your best/favorite story related to that plane.

Worldwide, in four turbo compounded Wright R-3350's, mounted on a large wing.

What airframe used those four Rows of radial cylinder engines ? The engines that overheated the 3rd and 4th row of cylinders in particular . Then suffered cracking when throttled back .
