Engine builders have grown
increasingly concerned that current engine oils that are API licensed for new
cars and trucks do not provide adequate wear protection for freshly built
performance engines, particularly those using flat tappet camshafts and
lifters. Royal Purple has addressed this issue with Royal Purple® Break-In Oil.
Royal Purple Break-In Oil is formulated to provide the critical wear protection
needed by the engine valve train and camshaft while allowing new piston rings
to quickly seat to the engine cylinder walls. Break-In Oil combines highly
refined mineral oil (preferred for engine break-in) with an advanced additive
package containing elevated levels of zinc/phosphorus anti-wear additive to
optimize wear protection during the sensitive engine break-in phase.
Royal Purple Break-in Oil is a fully formulated conventional 10W-30 engine oil
and does not require the use of any other chemical additives. Royal Purple
recommends switching to a high-performance synthetic Royal Purple engine oil
after break-in for maximum engine performance and protection.
We recommend using our Engine Break-In Oil for a minimum of 500-1,000 miles in
street driven gasoline engines to assure that the complete ring break-in has
been completed before switching to one of our full synthetic engine oils. If
need be, you can use for up to 2500 miles.
