Caltex tells me that the cetane rating for Vortex Ultimate Diesel is minimum of 46 (per product specification) and typically >50. Fatty Acid Methyl Esters (FAME) <5%. So really, Caltex Ultimate Diesel appears to be diesel with a small amount of biodiesel and an injector cleaner and antifoam and beyond that, it's all secret.
BP Ultimate Diesel product specification says it has a minimum cetane rating of 50 and typically 55-60. BP Ultimate Diesel is standard diesel with an additive package including:
1. nitro type cetane improver
2. injector cleaner
3. anti foam to prevent splashback
4. corrosion inhibitor
If you want algicide/biocide in your diesel, you need another additive. (Still using Morey's diesel smoke killer.)
