"tell me that fresh oil is bad for an engine"
I've heard re-refined oil is better than new oil.
Lets just say re-refined oil is fresh oil.
In the 16" X 20" x 8 in line Enterprise turbo diesel in a powerhouse in a mining camp in Alaska we used 30W. It had a 300 gallon dry sump oil tank. We had a re-refining machine there, re-refined the oil and used it again. Recovered about 80% of the oil. This was in the early 60s.
It took 24hrs of heating and other preparations to start the engine w compressed air. It started so slowly you couldn't tell the moment when compressed air gave way to combustion to run the engine. The flywheel just slowly gained speed and the noise slowly increased. It ran at 325rpm.
