A few months+ ago there was a Thread , I could not find with Search , regarding the failure of cam lobes due to the newer/modern engine oils not having all the additives necessary for the cam break in time period. Mentioned was the use of special lube for coating the entire cam and pouring over the lifter gallery and lifters, such as that sold by Comp Cam, ( Camshaft Break In Lube Part # 159 ) to be used when installing new cams. The cam failures were occuring even with the correct pre-lube of the cam lobes .
A mechanic mentioned that Shell Rotella multigrade 15W-40
oil contains the additives necessary to prevent the cam lobe failure.

While the
oil is primarily intended for heavy duty diesel truck use, it is also mentioned the
oil is appropriate for gasoline engines. COSTCO sells by the case, $46.99 for 6 one gallon containers.
Has anyone used the Rotella product ( s ) and any opinions regarding use for preventing cam failures ?
