Richard, all;

I've been running Avtur (JP-8 ?) in my 6.2 for 7 years without a drama.

Here in Oz we recently changed to low sulfur, and in some places ultra low
sulfur diesel and lots of people are reporting lubricity related problems.

I still say that changing, overnight, to BioD is less of a drama than when
we were forced to change to Unleaded.  ULP necessitated a change of engine
manufacture, BioD won't.  Further, think of all the additives in PULP and it
becomes quite acceptable to think that the addition of a small amount of
lubricating agent in BioD would not be an issue.

I believe France mandates 15% BioD in their diesel specifically to help with
lubricity ???

I've never considered myself to be a conspiracy theorist, but the more I
find out about BioD, excises, and fuel
companies.............................
