Location: Elk River, Minnesota | Hi,
About the only difference I have been able to see in any type of oil is how much smoke and residue you get. I happen to run Amsoil HP injector, and I love the stuff. It burns clean which in effect keeps the carbon build-up on the plugs down to a minimum. I can troll all day and not foul a plug. I think the biggest thing is sticking to something synthetic, and I believe the penzoil you are running is a synthetic...not sure on that though..
If you like it, and it doesn't load up your engine, and it is TCW-3 compliant, no need to switch in my mind...
