AVGAS TEST
Cross eyed.
Test Complete.
The two jars were opened at 8.30 this morning. both were still clear. There is a reasonable amount of sunshine. By 1400, both samples turbid with white precipitation at the bottom of the jar. The old fuel is more cloudy than the new, but the new is not much better. There is an approximately equal amount of gunge in the bottom of each sample.
The old fuel is OK for burning as Vfrpilotpb and I have just flown to the pub and back on it.
My verdict. Sunlight , and being in an open pot causes degradation of avgas which leads to precipitation of an unknown solid. The age of the avgas is irrelevant as it happens with new avgas. I will try to post a photo later to show what has happened.
I stick by my original statement that if it runs blue and crystal clear from the bowser I will burn it.
What you do with yours is your decision.
Hope this helps
EDIT:
At 1700 they are both more cloudy. The level has dropped by about a third due to evaporation. both samples have a greenish tint.
