Available exclusively through Crystal Flash®, Longevity Premium Diesel™ is designed to help keep engines cleaner, running stronger, and working longer. Available in three proprietary blends: Summer, Winter, and 50.
Longevity 50 offers the highest level of cetane improver available, which boosts fuel to 50 cetane or greater, improving the ignition quality of a blended fuel, fuel efficiency, and engine longevity.
Our diesel products clean and maintain your engine, extend the life of your equipment, and increase lubricity (EMA specification). The products also lower exhaust emissions, reduce engine misfires, and are compatible with bio-diesel fuels/blends.
Longevity Premium Diesel isn’t just sold by Crystal Flash, we trust it for our own fleet every day. Because when your equipment spends more time working and less time in the shop, every gallon delivers more value.
