I recently bought a used mini excavator that has a small 3 cylinder Isuzu engine. The lubrication chart says to use 10W 30 oil. Could this be right? I'm used to putting 15-40 diesel oil in diesel engines but I'm not familiar with these small diesels. I think I'm going to stay with 15-40 anyways? Maybe they just don't have 15-40 diesel oil in Japan.
