Gasoline Fuel poll : Engine, filter, fuel type?

I'm just curious what everbody is running for:
  • Year/Make/Model engine?
  • Fuel filter : 10 micron, 2 micron, or other?
  • Fuel : Regular, mid-grade, or premium? 10% ethanol or 0% ethanol?

You will probably find interpreting the answers rather confusing, as there is a strong UK bias to the forum where regular petrol (gasoline) is 95ron anyway. Very few people will be running 98 Ron here in a boat (hard to get and expensive). And if I remember correctly there are different international standards for Ron anyway!

I've never seen a choice for ethanol content in fuel in UK. I *think* forecourt fuel here can have 5%.

In the United States, we use (RON+MON) divided by 2 to find an average.

Typically averages to 87, 89, and 91...so about RON 93,95, and 97. There's a local gas station that sells 0% ethanol RON 97. I typically use that for boat fuel. Cost last week was $2.97/gallon, so about 0.52 GBP / liter.

For my little boat:
  • 1966 Johnson 9.5 hp
  • 30 micron inline fuel filter
  • 97 RON, 0% ethanol

I fill my boat tank through a "Mr. Funnel" water separating funnel.

1993 Evinrude 40HP 2 stroke tiller
Sierra 10 micron water separating fuel filter which is mounted to the transom.
I run premium in all my small engines, so 91 octane. Our fuel additives vary by the season. Not sure what it currently is spec'ed at and I don't really care, as most all of my small engines get run routinely, so the gas containers have a decent turnover. Used my top handle chainsaw today.

In boats use 10 micron filters and a fuel called 98 E5, its 98 octane and 5%ethanol. So far very good availability, and have not had any issues. Would rather use 0% ethanol content fuel but such stuff is not available anymore over here. Most common gas is 95 E10, but that's not suitable for older 2 smoke outboards.

Year/Make/Model engine? Yam F115, 2005
Fuel filter : 10 micron, 2 micron, or other? Racor 3213(?) 10 micron
Fuel : Regular, mid-grade, or premium? 10% ethanol or 0% ethanol? Regular unleaded; whatever is at the pump at the station I pull into.

Info won't be too helpful without a boat to match it to: Polaris Inflatables 18' Alloy hull.
