Avgas Quality

Unread post by Andrew Fletcher » Thu Jan 10, 2019 6:13 pm

Just a Heads-Up
SACAA seems to be concerned about possible contaminated avgas at some airfields.
A Notam was published very recently regarding this.
It requests pilots not to use fuel that seems suspect in terms "smell and looks", and to give a sample to CAA if suspect fuel is encountered.

....how can only one suplliers' avgas be suspect, the source is the same - looks like a go at certain suppliers to worm them out - ja boet it never rains.....

The language used in this notam is, in my opinion, not up to standard. I suspect this may be fake but I'm not sure.

Ray, the language used is probably quite up to standard - African standard ... #-o

If its 95 (green) mixed with 100LL (blue) you'll get cyan - not the easiest to detect
If its 93 (yellow) mixed with 100LL (blue) you'll get green

Don't know how else to detect if the fuel is cut apart from testing the batch in a lab, and to my knowledge our fuels don't have ethanol so the water test is also useless

Difficult to explain - but the smell is definitely distinctive. Smell some samples yourself and you will quickly notice the difference.

Agree, the supplier needs to answer some questions here!
