Good breakin oil
I used about 4 quarts of this to break in a new generator and then I switched to fully synthetic 10w30 and this stuff seems to work really good, the generator runs like a sewing machine

Generator break in.
Ran this for 3 hours w 30% load in my new Harbor Freight Predator 9500 Inverter Generator for a light break in. Came out really clean. Refilled w Mobil One 10w30 and will change again at 20 hrs. Hope it did the trick

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.

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.

I bought the wrong series, my bad ☹️
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 ☹️
