How Bad Are Cheap Diesel Motor Oils? $14 vs $58

From Project Farm.

Mobil Delvac, Rotella T6, Royal Purple, Schaeffer’s, Hot Shot’s and Amsoil. I paid an independent oil testing lab to analyze all of the motor oils, and I performed my own testing for lubricity, resistance to thermal break down, and oil flow characteristics.

I bought all of the motor oils, paid for the oil analysis, and all of the supplies used in this review. I always pay for everything out of my own pocket to ensure an unbiased review. So, THANK YOU for supporting the channel.
