Default INTERESTING FACT OF THE DAY

During WW2, the Luftwaffe got good quality avation fuel for their fighter aircraft from Romanian oil, typically 130 RON.

The RAF had equally good fuel, about 125 RON.

However American crude oil was of lower quality, and thus the fuel was more like 80 or 90 RON. This led them to develop protective additives like lead to allow more tuning of higher compression engines with superchargers. Eventually they had ratings of around 150 RON.

It was commonly recognised that the Germans had more powerful engines. Why was this? Because they had direct injection systems in their engines and this allowed them to use Nitrous Oxide while dogfighting, increasing power output by 50%.

I didn't know that.


Who's next for an I.F.O.T.D?
