Hello everyone, I am having trouble finding the correct 15w-40 non-synthetic engine oil for a 440 engine which came out of a 1970 roadrunner. Every single 15w-40 engine oil that I come across says its for Diesel engines. I am not sure if it will be right for the 1970 440 engine. Can someone who knows where to get this oil help me. Thank you very much.
