What to do with fuel samples?
I've been taught to always throw the fuel sample away e.g. on the ground. I'll always stick to that method but recently I have noticed some people taking the sample and pouring it back into the tank. From what i've heard " it may look good but there may be some invisible sediment in it "
Out of curiosity does anyone here teach their students to put it back into the tank ?

Never been an advocate of pouring it back in the tank - might there be some sediment in the receptacle which is being used which might end up in the fuel system?
I have asked our local GA field to provide suitable receptacles near the hangar for the purpose of disposing of fuel samples but have yet to see any! I believe that pouring samples away on the ground may be technically illegal and it doesnt seem very eco-friendly. Also it can erode tarmac if thrown away on such surfaces.
I was told that in USA you can be subject to a fine if you dispose of samples on the ground.

There are some samplers in the US which have a very fine fine strainer on half of their tops so you can pour it back in the tank safely. However if there's water in it, it doesn't seem smart to be hand-separating.
As I understand it, it is against UK health and safety laws to dispose of any fuel, particularly contaminated, other than into an approved container, which is then managed as hazardous waste. The individuals would be committing an offence of failing to dispose lawfully, as would be the operator for not undertaking a proper risk assessment and providing adequate waste handling facilities for known waste generated as a result of the business processes.

I ran out of barbi' lighting fluid once.....
So poured a VERY small quantity of 100LL fuel from the 'for disposal' jar over the dry coals and let it soak in. Then, to get it going, a little surgical spirit was also poured over.
Standing at a safe distance, I lit a match, then at arm's length holding it in barbecue tongs, held it over the coals...........
Well, yes, they certainly lit. A spectacular WHOOMPH and all the coals lit simultaneously! NOT the most sensible way of lighting a barbecue and DO NOT try it!
There's so much ludicrous huggy-fluffy Health and Safety bull$hit these days that it's simpler just to pour the fuel from a clean, sediment-free fuel checker back into the tank UNLESS there's any water in it.

I used to throw it away. After a while I thought that in a year I was sloshing away gallons of perfectly useable fuel for no good reason. If the sample looked good it went back in the tank.
I think thats much safer than the way some people take only a very small sample. I've nearly been caught by one being ALL water that smelt quite right. The second drafting was 50:50 so these days I have a big drainer or do it twice. Then it goes back in the tank.
If water has gotten in the tank then it can be a lot. I've drained over 8 litres out of a Pa38 left out in heavy rain with degradrd fuelcap seals.

In Africa the fuel sample jar was a 5 gallon drum
Which was then wheeled off and the contents sold to the locals for use in primus stoves.
Now would you call that good fuel management?

When I was teaching in avgas aircraft, I got all the instructors to empty their fuel samples into a small 20-litre drum. At the time, another instructor and I were riding old 250cc motorcycles so we both went forever without ever paying for fuel. It was environmentally friendly and made life that little bit easier for the poor old instructors making third world wages.

If the fuel is clear of contaminates, then why not put it back in the tank. If you're using a fuel strainer that wasn't clean, then you wouldn't know if the fuel was contaminated with sediment anyway. The GATS fuel testers are good for that because they have a filter.
Then again, I'm the kind of guy who lifts the hose in the fuel station to get the remaining dribbles out when filling my car!

Hello BingoWings,
Because typically your fuel drain is not an approved container. Once fuel hits it, it is considered to be contaminated. In Oz it's law - don't know about other parts of the world.
If the fuel is clear of contaminates, then why not put it back in the tank...

Turbine, thank you for your reply. If I were to transport or store fuel, then I would have to use an approved container. I think that is pretty much the same anywhere. But who's to say that the approved container is not contaminated? Is the container approved because it is suitable to hold the volatile liquid or because it is sterile? I personally think it is safe to carefully analyse the fuel and put it back.

Have seen people pouring it over the wheel. Pointless?
