 Posted: Sat Jul 10, 2021 7:49 am Post subject: Question for United States friends regarding E10 fuel |
 |
|
I'll get straight to my question which is "Does anyone in the United States experience problems in Europa aircraft fitted with Rotax 912 engines when using E10 gasoline purchased from car filling stations?"
Several weeks ago I posed this question to European pilots and got 2 replies indicating that they don't have problems using E10, which we are about to have introduced in the UK in September.
When I first addressed this question to the Europeans, I was unaware that E10 has been used in the USA for a few years. I only discovered this today, when I stumbled across a video entitled "Is Ethanol Bad For Your Car's Engine?" by one of my favorite automotive engineering experts. https://www.youtube.com/watch?v=ATGSBi1kBl0
Of course wear isn't the perceived risk factor for aircraft engines; it's water, carburettor icing, vaporisation and phase separation which are the causes of concern. These aspects weren't covered deeply in the video, which wasn't concerned with aircraft.
Several interesting responses were given on the forum when I last raised the topic, so I'm not seeking replies from outside of North America, thanks.

With over 1000 hours with a 914 and 912uls I’ve not had any problems strictly using e10. You want to keep it fresh though, less than 3 months old.

Jonathan,
Most auto fuel in the US contains ethanol but usually not more than 10% (https://www.eia.gov/tools/faqs/faq.php?id=27&t=10).
We use nothing but auto fuel in our 914 and have done that since new, now over 1100 hours. We have not experienced any problems with risks you asked about. Perhaps some of our experience is because we live in the midwest away from salt air and extremely high temperatures.
