Hi,
Is it true that truck engine oils are bad for engines passenger car diesel engines such as the 1HZ and 2L?
Mobil Delvac
Mobil Delvac: Commercial Oil & Heavy Duty Lubricants | ExxonMobil
and Castrol RX
Castrol Australia - Diesel Engine Oils
are both sold as heavy duty truck engine oils.
I contacted the Mobil customer support and asked if their heavy duty engine oils can be used in passenger car diesel engines incl the 4,2 litre 1HZ. They reply that I should strongly avoid heavy duty engine oils because truck engines are operated differently than passenger car diesels. I have a hard time believing that.
What is your opinion? Is it true that one should avoid heavy duty truck engine oil in our "small" Toyota diesels? Anyone with positive or negative experiences? Does anyone have a truly technical explanation or is it just commercial talk?
PS: I understand that Castrol RX is sold primarily in Oceania only and Mobil Delvac in America. Correct me if I'm wrong.
