From what the rep said...they do...Castrol makes all the Stihl oils
J2F
The 40-Fuel version of Truefuel is dyed green. Never ran the 50-Fuel. Since that can's red, I'll bet it has red dye.
Info from bobistheoilguy.com says that Omni makes Stihl HP Ultra.
Confirmed, TruFuel 50 is (very) red. SEF94 50:1 seems kind of green-blue.
Pb where are you getting the pails? I am just down the road from you. Russ
For the oil-concerned types, buy the straight SEF and put in your own oil. The 5 gallon pail is especially easy with a bottle of 5 gallon mix.
I prefer to get straight SEF94 and mix my own oil in it.
