Great break-in oil
Used this oil when breaking in my HF Predator 5000 Generator. Then I changed it out after the first 30 hours and now run synthetic. Good product, no regrets. Don’t leave it in the engine long term. It’s not made for that.

Royal Purple 11487 High Performance Engine Break-in Oil
Best break-in lubricant for a pistol and/or rifle that I've ever used. Stays put and does it's job. And this 1 quart bottle with lube my guns for years. Highly recommended.

In Soviet Russia, Oil breaks you.
It’s break in oil, fortified with vitamins and minerals. It’s like Brawndo for your small engine. Oil is cheap, engines are not. Follow your manufacturer recommendations for engine break in period and use this purple stuff for times good and bad. The molecules get to work filling in the micropores that would otherwise allow your metal molecules to weaken prematurely…I am not a metallurgist or chemical engineer, but I do play one on TV. I use this stuff for any four stroke small engine I need to break.

Brings out the shine and made our older truck beautiful again.
Best car wash ever. I was shocked at how good our 2017 truck looked after my husband washed it. It really brings out the shine.

Great oil and quick delivery.
Never can find this stuff locally, so it was nice to get it delievered quickly. It isn't cheap, but you do get value for your money with Royal Purple products.

It's oil, what do you want?
It's oil. No way I'll ever know if better for break in vs normal but makes me feel like I tried better. It is purple which is neat I guess, not sure if that adds value to something. Hopefully not just a wasted dye. It came in a bag wrapped in another bag. They are just screw caps to seal, no foil to break open. Arrived leak free.

The best.

Was shipped fast and was as advertised

I would recommend NOT putting this in a high-mileage engine. It’s designed to work with newer seals, and doesn’t allow for any aging in them. If you have a high-mileage engine, I would definitely recommend trying the RP HMX series oil, if you can find it in your required viscosity. Good luck finding 5w20 ☹️
