ash content on Shell Rotella oils

[706gas]

Does anyone know the sulfated ash content on Shell's Rotella T1 30W oil ? All I read it's a low ash oil,but can't find any PDS info on it .Thanks...

I'm assuming you mean their straight 30 grade. They call it low ash, but have no specifications to back that up, other than a TBN of 7.5. In any event, it's a CF-2/CF diesel only oil, and those specs are rather dated. I don't think there's a low ash requirement to those specifications.
