As for E10 causing problems, I'm still waiting for one from my "fleet" which includes:
1. Three garden tractors that are 25-45 years old.
2. 1977 boat with a carbureted I/O engine.
3. 1967 Vette with 3 carbs.
4. 15 year old string trimmer.
5. McCulloch chain saw from the 60's.
6. Genset in my 2000 MH that spends the winter with its tank full of E10.
7. 1977 IH Scout.
8. 1994 Topaz with 233,000 miles (it has sat outside for the last 10 years).
9. Four newer vehicles with FI engines.
10. A 20 year-old 72" cut commercial lawn mower.
11. A pressure washer (Honda engine), but it's only a couple of years old.
