for starters, you won't be using any E85, and E10 will be no problem if you don't store it unused for long periods without a preservative like Stabil .... the lack of lead doesn't hurt a thing, especially on a newly rebuilt engine that should have gotten hard seats ... then it's the oil that prevents wear and good hot runs when you use it prevent 'gunk' - as well as regular oil changes of course .... just drive it and enjoy it
