I have a GMC Yukon XL with & have wondered what are some of the best oil filter brands to use. I drive mostly highway miles & occasional dirt road driving with 8,000 mile OCI which is usually when the OLM says to change it anyways. I run either QSUD or Pennzoil Platinum when its on sale. I am not saying that the most expensive filter is what I want, I want what is proven from others. I am always open to others expertise as long as it proven knowledge not just this is great because I spent a lot of money on it.
