I bought a brand new 2000 watt Powerhouse generator for home use. The unit had been test run and had traces of oil and gas in it. The manual specified ONLY 15 w 40 oil for all usage over 32 degrees F. I used Shell Rotella 15 w 40 dino since it was available at Walmart. I test ran the genny for 2 hours, using an electric heater to load the engine and make sure it was putting out power. After 2 hours I changed the oil and it was very dark. I have never seen oil darken up this quick. Has anyone else seen this? More importantly, does this indicate a problem? I plan to change oil after every weekend of use until things clean up.
Thanks in advance for any advice Oldtom
