This.Been on corn since 2016. No issues, and I would never go back. I average 1k-1500 miles a year. Car sits 6-8 months straight all winter and have no issues firing right up in the spring. I run a vented catch can, drain the condensation out of it every time I take the car out. Besides that, nothing out of the ordinary besides basic maintenance…. Oil change every year, clean the fuel filter too.
I’ve got a friend that had gone 2 years without running the car on corn and still fired up fine. Anyone who tells you not to run corn doesn’t know anything and I wouldn’t listen to them. Does it burn more fuel, yes. Is it worth it for 100-150 more HP, yes. Is E85 safer, yes. Does it smell good out the exhaust, yes.
I fill 8 VP cans at a time. Sometimes I store it for 8 months in the sealed cans. Still tests the same and has no effect on how she runs.
