Royal Purple 10W30 Motor Oil, 1 qt Case of 6

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. To address this issue, Royal Purple has developed Royal Purple Break-In Oil.

Royal Purple Break-In Oil is engineered 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. This 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. The result is optimized wear protection during the sensitive engine break-in phase.

Designed as a fully formulated conventional 10W-30 engine oil, Royal Purple Break-In Oil 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.

For street-driven gasoline engines, Royal Purple recommends using the Break-In Oil for a minimum of 500-1,000 miles to ensure complete ring break-in before switching to a full synthetic engine oil. If needed, the Break-In Oil can be used for up to 2,500 miles.

Packaged in six one-quart bottles, Royal Purple Break-In Oil features highly refined mineral oil and a zinc/phosphorus anti-wear additive formulation in a 10W-30 weight.
