On the recent Marvel Mystery
Oil thread it was mentioned (by more than one) that modern
oil has everything you need all ready in it, no need to add anything. Well OK then... It was also mentioned Ford and other manufacturers know whats best for their motors. No doubt thats true, for their MODERN motors! Does Ford even make a flat tappet engine these days?
Newer is not always better.
The camshaft makers, the modern
oil engineers and many others have lately been saying, "Oops".
NOTE: I don't recommend Marvel Mystery Oil as a supplement to save your flat tappet cam. Nor is it useful for brushing your teeth, washing your hands and many other things. It has it's place, use wisely.
