Product Description

Size: 1 Quart (32 Ounces)

Engine builders have grown increasingly concerned that many modern motor oils do not provide adequate wear protection for new engines, particularly those using flat tappet cams. Royal Purple has addressed this issue by developing a new engine break-in oil. Royal Purple Break-in Oil is formulated to allow optimal ring seal and protect rotating assembly components such as the camshaft and valve train from initial start up wear. Royal Purple combines highly refined mineral oil, preferred for engine break-in, with advanced additives containing high levels of zinc and phosphorus to optimize protection in flat-tappet and roller engines. Royal Purple Break-in Oil is fully formulated and does not require the use of any other chemical additives. Royal Purple recommends using their high performance motor oils after the engine is broken in for maximum engine performance.

I bought this to add some protection to a new engine I built. Typically, you don't run a synthetic to break-in a new engine, so RP came out with this. It is a non-synthetic oil that has protection additives for engine break-in, but does not prevent the rings from seating. It is not meant for an extend drain interval.

it is a straight 30w dino (mineral oil) I used it to break in my New 454 from GM- The 1st I changed after the 1st 100 miles, then at 1,500 miles and every 1,500 miles until it had 5,000- then I used RP 10w 40 until 8,000 miles. At 22,000 miles I have 70 -80 Lbs. of oil pressure w/ a 195 degree thermostat - I followed "Motor Man's" break-in procedure - don't allow the engine to stay at any steady RPM until you have 8,000 miles (run it up to 3,500 stay in gear while it backs off until 1,00 RPM) the 1st 100, 500 and 1,500 miles are critical- I hope this helps, I couldn't be happier with my K-2500

Mineral oil with additives. Used the original oil for 600 miles then used this one up to 2,000 miles before changing to synthetic. Expensive but reputable brand. I use same brand for differential gear oil on my truck and the drive shaft for my bike too.
Tip: Don't forget to have the valve clearances checked after break-in. Mine did not need adjusting but its good to know and to be safe on the warranty. The more practical schedule would be in 10,000 miles.

I haven't used too many different brands of break-in engine oil so I cant compare. Use a break in engine oil for two reasons, it helps break in the cams and lifters, and it helps seat the rings. Cams are often broken in the first 20 miles, rings take a little longer.

As with all royal purple oils, this one flows purple! I used for the first 100 miles and had great results.

I used this oil to break in a 273 with new flat tappet cam and lifters. I was using double spring valves and didn't bother taking the inner spring out. I had no wear upon break in and use RP oil in all my engines.

The Best Oil Made today. I put in my 1934 Ford Roadster that I just restored including rebuilding the power plant V8 babbit bearings.. The engine runs like a Swiss watch. Very satisfied with the additives and properties that Royal Purple uses for breaking in newly rebuilt engines. Best insurance I could buy for the start up..
