I can tell you this Brad, A friend of mine use to race cars all around the country. He used Mobil-1 in his race car. Because of that, I've used Mobil-1 in the last three trucks I've owned. I bought a 2008 GMC 6.0 last year. I switched to Mobil-1 at the first oil change. Never had any problems useing synthetic oil. The engine turns over easyer in the winter. Neither the starter, or anything else has to work as hard in colder wheather. I pull a trailer daily, up and down hills. The truck works for a living. And that's where the synthetic oils shine, is in extreme conditions. I stick with Mobil-1 because of it being more readily available. They claim Amsoil is a little better. And Royal Purple a little better yet. For the average person who uses the pick-up mostly as a second vehicle, I'd stay with regular motor oil. It's a lot cheaper. I changed my oil today. Six quarts of mobil-1, and a mobil-1 oil filter $59.36. That's with me doing the work.

After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
