Specifically designed for breaking in engines and flat tappet camshafts and lifters, BR break-in oil provides high levels of Zinc, Phosphorus and Sulfur in a mineral base oil. BR protects flat-tappet camshafts and lifters during break-in and it provides excellent ring seal. Combined with Joe Gibbs Driven Engine Assembly Grease, BR provides the highest levels of protection for camshafts, lifters, wrist pins, distributor gears, push rods and valve retainers. BR is fully formulated and requires no EOS or other additives. BR should be pre-heated to 180F before firing the engine for maximum protection. Because it is a 15W-50, BR can be used for up to 2 hours of break-in/dyno time before changing to race oil.
Editors Comments:
The world has changed. Some would say for the best. An engine builder would say for the worst. "They don't make them like they used to." This comment applies not only to today's lower octane fuel but also to today's engine oils. Let's not get too technical. All of the sudden, camshafts and lifters are failing left and right. "I've never had a cam fail in 30 years, and now I've lost two in the last six months." I've heard this comment too many times. Save your time, save your investment. You've spent all this money on items that probably won't really increase your performance or horsepower, but now the engine is at risk of premature failure because you didn't break-in your cam right and didn't use the right oil or additive. You learn this right before you have a 20 hour labor job, gasket set, and cam and lifter kit purchase ahead of you. You realize that in engine oil, "zinc", "phosphorus" and "detergent" levels do matter.
Bottom Line: You must at least use a high zinc additive along with your engine oil during start up. Sure, it's a little better to use some Rotella 15W-40, but even that's not the same it used to be. The best is to use a break-in oil that's been specifically designed for engines with flat tappet lifters in mind. Don't risk your Chevy 350, 383 stroker, or Ford 302, 351 or whatever you are working on. And, super important, don't forget to hold those RPM's at 1500 to 2000 for the first 20 minutes of start-up unless you enjoy doing rework for nothing. (And enjoy an unsympathetic customer driving you nuts, criticizing your engine building abilities.) Then. be sure to dump this within 500 miles. |
