Now that I have my filters I have a question about oil grade.The sticker on the hood says 10w40 CD or better in summer and 5w30 CD or better in winter.I was told that this grade doesn't exist for diesels.The owners manual says for summer Sae 20 or 10w30 or 10w40 and winter sae 10w all class cc or better.also the injector pump is the same.should I go with the straight 20w or15w40 or synthetic
