Let's consider a typical passenger car or truck operating normally. We can all agree that over time with use, the oil becomes ineffective and that is why we change it out every so often.
Where do you think oil takes the most abuse? Would it be:
1. The shear with lobes on the camshaft?
2. The shear in the crankshaft main bearings?
3. Piston under crown/oil control ring area?
4. The heat produced from combustion being transferred to the oil?
5. In the oil pan due to piston blow-by (air/fuel blow-by or combustion products blow-by)?
6. Any shear caused by the timing chain?
7. The shear of the oil going through the gears of the oil pump?
8. Others? (e.g. turbos if equipped)
Looking forward to seeing your opinions.
