AC Delco makes blue filters, and Wal-Mart carries those. But I don't know if Delco makes a filter that fits our bikes. They usually cater to GM vehicles. I use a Wix filter myself. You can argue about different brands of oil all day long, but seldom has anyone produced any evidence that low dollar oil destroyed an engine. However, cheap oil filters have destroyed engines. I worked at a parts house years ago, and we supplied a new engine to a customer who's original engine failed thanks to a faulty seal on his Fram oil filter. Fram bought the engine and paid for the installation, but the customer had to do all the leg work, as well as find alternate transportation while he waited on the warranty to go through.
