FC help stabilize the fuel?
Yes. However, PMC recommends the use of DuraSta® which has shown to restore the fuel quality of deteriorated fuels. A single treatment of DuraSta® will provide fuel stabilization for up to one full year. DuraSta® contains the key additive components of DurAlt® FC. Fuel that is regularly treated with DurAlt® FC will not require the use of DuraSta®.
