CNG, LNG, Propane vehicles only. 5.8 TBN
"Valvoline’s Premium Blue GEO is a low ash, SAE 15W-40, engine oil recommended for use in urban bus, delivery truck, and other service fleets fueled by CNG (Compressed Natural Gas), LNG (Liquefied Natural Gas), or propane."
Just saw this on their site, when I was looking for a MSDS sheet.
Are they no longer making the regular Valvoline Premium Blue? I haven't seen this 'new' jug on the shelves yet....what gives?
Valvoline Premium Blue is used in natural gas engines. Most commonly I use it in large stationary commercial generators that use popular diesel engine blocks (C8.3, N14 or 855, K19, etc) as the base for the natural gas conversion.
They still make the regular Cummins Premium Blue!!
