Hi. I'm new here and to owning a bmw. I recently bought a 2002 e46 318i with the 4 cylinder m42 engine. The car has under 75,000km and the previous owner did an oil change before I bought it.
He told me he put in a 10W 30 oil which he says he uses in his other bmws. I was just curious, considering the hot climate we live in here (Trinidad), if I should stick with this type in future or up the viscosity slightly.
Advice appreciated in advance.
