Im well aware that oil breaks down ....what I am asking is if anyone has heard of a true "Oil related breakdown"
like "well.....your oil wasn't in very good shape after the 1000 miles of driving you have done. we tested it and I don't think that you would have spun that bearing if you were using XXXbrand cause it is way better oil"

Thats all...I do understand the logistics of oil breakdown...just dont know that it is as important as people make it out to be ?
Just being the devils advocate when it comes to all this hype about oil!???

Mobil 1 15/50 supposedly has ZDDP added back into it to address camshaft issues. We run it in our Chump Car miata for racing.

Pennzoil Ultra is fairly new and claims to do a great job cleaning the engine. I run the 5/30 in the Expedition - not 20 weight.

Pick the right viscosity and keep it clean. This topic can lead to OCD.
