SEF Multi-Mix provides ethanol-free, 90-octane performance with the highest quality broad-spectrum synthetic 2-cycle lubricant on the market, making this the perfect blend for both 40:1 and 50:1 applications. SEF's proprietary lubricant exceeds industry standards for lubrication both JASO FD and ISO-L-EGD. SEF also provides easier and more dependable starts. Pump gas can contain up to 15 percent ethanol, which will absorb moisture and form deposits in carburetors and fuel systems, making equipment hard to start and often requiring complete rebuilds. SEF solves long-term storage problems, allowing easier starts even after equipment sits idle for months at a time. It saves money in the long run by avoiding the lost time and expense of costly rebuilds. It's good for storage of up to two years in a vented tank and five years in its factory-sealed container.

  • Small Engine Fuel Multi-Mix with 5-in-1 Additive
  • Ethanol-free 90-octane unleaded fuel for outdoor power equipment
  • Contains a JASO-FD certified, 100 percent synthetic 2-cycle lubricant
  • Meets mixing ratio standards for 40:1 and 50:1 spec'd equipment
  • Store up to 2 years in vented tank or up to 5 years in factory sealed container

Q: How can it be 40:1 and also 50:1 40:1 uses 3.2oz of oil to gas in the mix,and 50:1 uses 2.6oz of oil to gas so wouldnt it ruined one or the other engine that uses the opposite mix ratio

  • A: Per the manufacturer: ". The fuel is marketed for both 40/50:1, as our clean burring ethanol free fuel and full synthetic FD rated oil works well and provides good lubrication for most all applications. We believe any 40:1 or 50:1 piece of OPE will run much longer on our fuel and oil than on cheaper oil and pump gas, and yet pump gas will meet manufacturers recommendations. We offer both a specific 40:1 ratio and a 50:1 in addition to the Multi-Mix, and always recommend you follow your manufacturers' recommendation."

Order canceled and did not return market points

a month ago
I would rate the product but never got it. Tractor supply canceled my order for unexpectly became unavailable. Best part is they did not return my neighbors club points or replied to my request to return my points. Just a bad company to deal with now.
