This is what 200,000 miles looks like on a Honda four-banger. AMSOIL Signature Series Synthetic oil at the factory recommended intervals (which usually works out to 10,000-11,000 miles.)
I do change the filter at every oil change instead of every other change per the factory recommendation.
There isn’t a single bit of sludge here. This looks exactly like it did 170,000 miles ago when I had the valve cover off the first time.

I started working with Michael Sparks back in 2013 to help solve a smoking issue in my sons 2 stroke motorcycle. He helped me understand why AMSOIL products are superior to other lubricants available off the shelf. Since then I became an AMSOIL preferred customer and use the products in my vehicles and other equipment.
Anyone who wants to take better care of their vehicles and equipment should get in touch with Michael Sparks to find out how AMSOIL is The First in Synthetics.
