I had a Generac Guardian running continuously for two weeks. At the end
of the two weeks I checked the oil and it was so low the dipstick came
out dry. We added almost a quart.
It's 990cc engine with an aluminum block. I've heard aluminum blocks
can drink oil because they expand more with heat as compared to cast
iron.....but as contrary evidence my Hyundai Elantra has an aluminum
block and doesn't lose oil over time.
The manual says to check the oil daily if you're running continuously,
but I thought they were just being overly cautious. The genny's brand
new so I'm kind of stunned.
Could this really be normal?
