1 case of RED MAX Brand 2 cycle mix oil. Each case contains 48 (8 six packs) 6.4 oz. bottles of the premium oil RED MAX and many other quality brands recommend. Note that it has the "FD" rating ( on the back of the bottle ), indicating the latest additives are it in to make work safely at up a 50:1 ratio. Just pour one pre-measred bottle into 2.5 gallons of fuel. Some guys use one bottle in just 2 gallons for added safety. Also contains a fuel stabilizer to keep mix fresh and volatile.
