Seafoam as an oil additive

We just covered this Recently.

There are products made specifically for this but NONE that you will want to Fly the plane with.

Fly the pattern to heat and thoroughly mix the oil, then land, add the Snake Oil, and Idle under 3000 RPM for 10-15 minutes.

Finally, drain the oil without delay before it has the chance to settle again.

Plenty of folks bring their own MoGas to the field.

If your FBO gives you grief, remind him that Unleaded MoGas IS the recommended fuel and that you would be happy to buy his if he wanted to start supplying it.

The cans you want are VP Racing Fuel Jugs.  Google it!

They are labeled as 5 gallons for legal purposes but will hold 6+ gallons if you fill them to the top.

Hint: the square version takes up the least floor space.

You do not want anything larger because of the weight.  6 gallons plus the can is just over 40 lbs.

Be sure to buy the RED colored jugs because it is illegal in most states to put Mogas in any other color can at a retail gas station.

Nobody will probably notice or care, but why set yourself up for grief?

You can often find these for under $20 locally or a case of 4 for under $100 including shipping from online sellers.

These are better made than anything you will find at the big box retailers.

Agree with Bill 100%,

I have been using Mogas in my 912IS for 650 hr, I am over 60 and the workout is great. The only thing I would add is that I have two 20L collapsible "Jerry cans" that I take on long trips

very useful and fold up nice in the plane...
