Leaded Avgas reducing flight safety?

Just paid £80 for a 0.5kg reel of Japanese silver/copper/tin solder - must be a world record.

Some EU politician must have bought a lot of shares in a silver mine

It is good stuff though - really works.

So, when we get 100UL at €4/litre we can have a fly-in to celebrate our green credentials.

Where shall we go? To make it truly authentic one needs to burn a lot of fuel to get there, so how about Finland, or Crete?

How about installing a dumping valve in your TB20?

benzene is often up to 1% or 1.5%.

Benzene is now limited to 0.61% in the US isn't it?

Regarding unleaded solder... Who cares if the joints don't look as good as lead-solder joints? Reliability is important, but my understanding was that the aviation exemption was more about the incompatibility of old leaded components and new unleaded solder. You don't get reliable results if you use leaded and unleaded solders or components so an outright ban would have created havoc.

Again, thinking back to my childhood exposure to lead from disassembling electronics I'm glad I don't have to handle the stuff any more, and that my son won't either.

I flew my mates 150 again last week. Its currently having a 50 hour check every 6 days and that has been the case now for the last couple of months.

There is about 1800 hours on the engine and the last 1300 have been on UL91.

Oil wise is always been run on aeroshell 15/50 and had about 5 hours before its next service was due.

I absolutely couldn't believe the colour of the oil. Whereas the 150s that we run on avgas by time their 50 is due the the oil is the colour or tar.

However with this aircraft the oil was still a translucent brown admittedly darker but a world away from our aircraft.

I would also add that I have flown this aircraft throughout its engine life. Including when it was initially run on Avgas and I am certain that the colour of the oil is vastly different when run on unleaded fuel.

Well my theory just took a bit of a dint as the compressions have just gone on one of the cylinders. It has 1900 hours TT with the last 1200TT being on UL91.

Not had any plug fouling in all of that time and the oil is much much cleaner.
