I recommend the original furmula Kendal Racing
Oil that is available only from specialty racing suppliers. It is not available on the shelf of your typical retail auto parts store.
Recently had an amazing experience to prove the value of this stuff. Five years ago I had put this
oil in my rebuilt side oiler and pumped the
oil through the engine by turning the oil pump drive with an electric drill. This was done with the anticipation that I would not be able to use the motor for a few years, so I sealed it in a crate and stored it in my garage.
Last month I decided to uncrate it, change the oil and circulate it before going any further. I bought some oil from my local auto supplier and proceded to remove the valve covers and inspect the condition of things. When I saw the incredible clean condition and this Kendal oil still sticking to all the parts, I kept the same oil in the motor and just changed the filter and pumped the oil through again. I refused to put any of this new low quality oil in my side oiler until I could find the original stuff.
Here are some comments I found from Schneider Cams during my research.
To our valued customers:
As many of you already know, there have been dramatic increases in flat tappet camshaft failures over the past few years. According to our research, this is due mostly to recent changes in motor oil formulas. Current strict emissions standards have pushed the oil companies to pull
zinc, phosphorus, and other high pressure lubricants (ZDDP) out of the oils. The fact that most, if not all, late model motors are factory-equipped with roller tappet cams allowed the change. This has become so problematic for the flat-tappet world that Hotrod Magazine published an article on the subject [When Good Cams Go Bad, June 2006]. The life of a flat tappet camshaft depends on proper lubrication. Inferior oil formulas put your camshaft and motor at risk!
