Hello everyone,

Over the months, the topic of what type of gas to use and what about ethanol keep coming up so I thought I would try to dispel any myths and/or questions and bring you the information straight from the “horses” mouth (that’s Mercruiser, not mine…).

I spoke with Mercruiser Service and the bottom line is, they designed their engines to run on 87 octane and with up to 10% ethanol, but you can use up to 91 octane if 87 causes any pinging. Any higher octane is not recommended unless you have a specific engine designed for it.

These articles are from Mercruise’s website.

Here is what Mercruiser recommends for fuel and oil: Click here

This is Mercruiser’s information on Ethanol: Click here

I hope this helps clear up any questions on what type of gas, Ethanol, etc…
