I'm thinking the 120 four stroke would save over $100 next season as fuel here is $30+ per gallon (10%)
You are in a situation where it might be beneficial to order fuel and have it shipped.
www.magnumfuels.com
Sport Fuel $19.00 per gallon buying 3 to 5 cases (12 to 20 gallons)
15% nitro
13% synthetic
5% castor
Other oil packages are available
Same fuel with 10% nitro is $18 per gallon
This price includes shipping to a business address. I have a friend who runs a body shop; maybe you know someone who could receive the shipment?
You'd want to verify with Magnum whether a hazmat fee would be added.
In 2003, several of us got a 35 case order together and Magnum gave us a club discount in addition to the "16+" case price. People bought everything from FAI to 30% heli. The fuel worked as well as any other brand, and my last gallon was just used up this year.
My fuel had a 5 year shelf life, with no issues, so don't be afraid of buying 12 gallons. The hard part is turning loose $216 to 228 in one chunk.
