All fiberglass fuel tanks need to be replaced and made unserviceable: we had an accident where the fiberglass tank leached resin into the fuel causing an engine stoppage with a subsequent forced off-field landing. Strong words I agree, but I stand by them 100&. The unfortunate pilot DID survive, but has since stopped flying.
Hello , I am watching your video on 10 percent ethanol gasoline . The E10 sample you show here is clear , is this regular grade ? I operate an ATV / UTV service shop and constantly deal with bad gas . I advise all customers to use only High test gas in the hope that it is ethanol free which it may or may not be . Here in NS regular is yellow and high test is clear which tells you nothing about the ethanol content but tells me what grade customers have been using . If I find yellow gas it is guarantied to have 10 percent ethanol and the clear hopefully pure ???????
Hi Kieth, the clear sample was E10 87 octane and the other yellow sample was neat 91 octane. This was interesting, I just purchased 50 litres of E10 87 that had no ethanol content. I was surprised, tested it twice and still got 0 % ethanol. First time that ever happened. I test every fuel purchase for ethanol %. The food coloring drop in a fuel sample is the fastest way to find out if it’s neat or E10.
Wouldn't running 91 still be a good idea to fight against the loss of octane over time? Though I guess there's no reason to pay more if you know you're going to burn it off ASAP. BTW my local Shell's 91 is still ethanol-free according to my expensive little water bottle.
I apologize, I thought this was about cars. However I did learn something important, so now I have to redesign the gas tank on the motorcycle I built from scratch.
We still have ethanol free 91 available in Alberta fortunately. I fly two different machines with fiberglass tanks, and so I have been checking for ethanol since it was legislated many years ago. If/when I can’t get ethanol free fuel anymore, I will be replacing the fuel tanks.
In Canada we use the A.K.I (anti knock index) gasoline rating system. I believe Sweden uses the R.O.N. (Research Octane Number) . Our regular grade 87 would be roughly equivalent to your 91-92 grade
I believe 91 is specifically a blend of alcohol and gasoline that's only for use in cars specially tuned for 91. I could be wrong, but I don't wanna be.
I believe the two types of ethanol are pretty much the same, one variety has a slightly higher octane rating. We have been traditionally been using 91 octane, no ethanol car gas in our non certified aircraft. I have an antique car with a metal fuel tank, lots of corrosion in its fuel tank coming soon!
It’s unfortunate that the alcohol content of the fuel is not clearly displayed on the gas pumps - leading many people to be unaware of the recent changes with potentially disastrous consequences such as engine damage/failure.
It would be proper for the gas stations to label the fuel correctly, however it is automobile fuel and not aircraft fuel. Electronic self tuning car engines using plastic fuel tanks are actually not real fussy about what the engine consumes. Our aircraft are definitely fussy about the fuel we burn. As pilots we must be more vigilant than ever before on what goes in our fuel tank. Thank you for your comment.
I've never seen this test done before. Thanks so much for bringing it to a wider audience - I'm sure it will be useful. All fuel here in the UK has ethanol in it now but we can still buy 5% on the more expensive pumps.

I absolutely agree with you. Better to find out now and deal with a fuel tank replacement before the engine stop operating.
excellent vid - informative. Thanks. ps: so glad you didnt edit out the "real life" dropping of the second sample.
Thank you for your positive comment.
Because of this situation in Canada, is why I will be running 100LL in my Rotax 503.
Good plan, I’ll be replacing mine with aluminum. I can’t purchase 100LL in a carry away container in my local area.
A lot of rotax experts recommend against the low lead due to the extra spark plug deposits.

I have always suggested that after 30 days to drain the fuel out and dispose of it in your cars tank. Fresh fuel is best. Thank you for your comment.

I’m very happy you learned something. The truth is not the enemy! As I stated, better a new fuel tank now than an engine repair and a fuel tank later.

Way to go Alberta! You get top marks for taking that extra step of actually testing your fuel for ethanol. Happy flying.
Wow. Thanks. Here in Sweden we can buy 95 and 98 okt. at the gaze station. I dont know how to compare to Your fuel . . ?

I love your videos John! Thanks for doing them!!
Glad you like them!
there was or is a video of a guy adding water and letting it sit till the ethanol and water settle out of the fuel creating ethanol free gas
Absolutely, they call or washing out the ethanol. The big issue I see with that is what would the octane rating be after the ethanol is removed?
Great video, thanks for the demo. Keep up the great info.
Thanks, will do!
ethanol fuels are the two stroke engine killer...
The neat 91 will be sadly missed.
👍
Thank you

Glad you found this video useful. My original intention was to easily identify neat 91 car gas vs 10% ethanol 91 car fuel and it just went from there.
@@RotacRepair Well I'm glad it did! 😁😁
