1. A Take equal samples of both fuels, elevate their temperature, mix them vigorously. If no frothing occurs, they are compatible.
2. B Use blotter paper with a single concentric drop of 'old' and 'new' fuel, if they do not form separate circles, the fuels may be deemed compatible.
3. C Mix two equal samples of the two fuels at elevated temperatures and determine if they become a homogeneous mixture.
4. D Perform a running viscosity test of both fuels, at the same temperature, if the viscosities are equal, they should be compatible.
