Obviously I agree. Several years ago I bought a Honda magna motorcycle. I used GN4 for the first couple oil changes then I switched to Mobil 1 4T which is another good choice for synthetic. It made a huge difference in shifting. Ever since, I've used only synthetic in all of my engines. It really does make a difference! In some machines you can't really tell a difference, but not the P500! I did some work with it today. In all situations, it shifted better and smoother than it did before using the Amsoil. I'm very pleased with the results.
I worked the P500 hard today. Pulled out 4 good size sumac trees on my property. And a friend came over and helped clean up some junk. Used the "cute" little trailer to haul a ton of rotten wood and other junk and burned it. My Pioneer might be a toy, but it's definitely pulling its weight when it comes to getting some work done!
