"Money can't buy happiness -- but somehow it's more comforting to cry in a CORVETTE than in a Kia"
Engine Start Up Procedure Regarding
Oil/Additive Usage in Flat Tappet Cam/Lifters
With the absence of lubricating chemical (ZDDP) in the present day
Oil from the oil companies available to consumer for typical oil changes
It is highly recommended to add or use oil with the ZDDP available
In the oil you purchase. The Zinc Phosphate combination acts as a
Lubricating agent to reduce friction on the lobes and base of the lifters.
The EPA had mandated that these products (chemicals) be eliminated as it
Deteriorated the catalytic converter thereby increasing pollution.EPA
Sacrificed the metallic parts of the cam/lifters for the life of the converter.
The late model engines now have Roller Cams and Lifters and do not
Require the ZDDP albeit I would recommend using the additive or buy
Oil with zinc phosphate available in the formulation.
To help identify the oil with ZDDP in the formulation, look for the
Round badge on the oil container that signifies API Service CI-4/SI
CI-4 Plus would also be indicated.
Be aware without the use of this type of additive or oil containing ZDDP during break in of cam/lifters along with normal operation of the engine would void the warranties you may have received from builder of the engine along with/cam/lifter manufactures.
