Went to change oil in my Cat skidder today (3304 motor). So I went to napa to get oil. Guy gave me some Valvoline engine oil and I didn't notice it is not specific for diesel motor. It was on shelve above the synthetic for diesel thats why I didn't notice. Anyway my question is should I be using a oil that is made specificly for diesel or is what I bought fine?
