Proven by Independent Testing

Eight major brands of diesel fuel additives as well as a base ultra low sulfur fuel were tested by a leading independent laboratory in three key areas:

• Cetane number (affects ease of starting, noise, power output and emissions)
• Lubricity (critical with today’s ultra low sulfur fuels)
• Cold weather protection (against waxing or gelling diesel fuel)

The results shown in the charts are clear — Stanadyne Performance Formula is the best
in all three tests.
