Where did you read that there were a difference between the grey and white bottles? I read em label for label and they were identical!
I use the white bottle only time I ever had issues was when I forgot to put it in and it hit -10 degrees
White bottle is what I run also...here it is..
Gray bottle (off there website)
Prevents injector sticking in High Pressure Common Rail (HPCR) systems
Cleans dirty injectors
Boosts cetane up to 6 numbers — engines run smoother with less power lag and faster cold starts
Decreases fuel consumption up to 8% — fuel savings exceed cost of additive
Boosts power — reduces need for downshifting during high-load conditions
Contains Slickdiesel® for maximum fuel lubrication — protects fuel injectors and pumps against accelerated wear from Low and Ultra Low Sulfur Diesel (ULSD) fuels
Prevents thermal breakdown of diesel fuel — protects against sludge formation that plugs fuel-filters and injectors
Stabilizes stored fuel
ULSD Compliant — contains less than 15 parts per million (ppm) sulfur
Effective in all diesel fuels, including ULSD and biodiesel

Winter Performance Benefits:
Prevents fuel gelling in temperatures as low as -40°F.
Equals performance of a 50/50 blend of No. 2 and No. 1 diesel fuels
Lowers Cold-Filter Plugging Point (CFPP) as much as 36°F. — keeps fuel-filters from plugging with wax
Boosts cetane up to 4 numbers for faster cold starts
Contains anti-icing additives — protects against fuel-filter icing
Contains wax anti-settling dispersants — protects against fuel-filter plugging at temperatures below the fuel cloud point
Year-Around Performance Benefits:
Contains Slickdiesel® for maximum fuel lubrication — protects fuel injectors and pumps against accelerated wear from Low and Ultra Low Sulfur Diesel (ULSD) fuels
Boosts cetane up to 4 numbers — engines run smoother with less power lag
Boosts power — reduces need for downshifting during high-load conditions
Keeps fuel injectors clean — including High Pressure Common Rail (HPCR) injectors
Decreases fuel consumption — fuel savings exceed cost of additive
Disperses water in diesel fuel
Improves diesel fuel’s resistance to thermal and oxidative degradation — protects against sludge formation that plugs fuel-filters and injectors
ULSD compliant — contains less than 15 parts per million (ppm) sulfur
Effective in all diesel fuels, including ULSD and biodiesel blends containing up to 20% biodiesel (B20)
