10W40 Driven Racing Oil BR40 Conventional Break-In Motor Oil

Driven Racing Oil BR40 Conventional Break-In Motor Oil features the same high zinc and phosphorous formula as Driven's original break-in oil—now in SAE 10W-40 viscosity. It's well suited for classic muscle car, European sports car, and motorcycle engines. The special lubricant is ideal for flat tappet and aggressive roller valve trains, as well as ethanol blended, pure methanol and oxygenated race fuels. This oil does not require additional ZDDP additives. BR40 Break-In Motor Oil is good for dyno testing, one night of racing, or up to 400 miles on the street. (NOTE: Driven BR40 is a break-In oil and should only be used for engine break-In. This engine oil will NOT meet any current API or OEM engine oil specifications, as it's formulated specifically for engine break-in only.)
