[4th Gen : 01-07]: My 3yr UOA Study: 0W-20 vs. 5W-30
#11
The wear is accumulative, but the 0W-20 also had more the twice the ppms, so regardless of how minuscule the wear may be, it's still wearing more. Any difference in wear is meaningful. It may be the difference in making 200k or making 500k. I prefer my vehicles to last.
It's hard to tell for sure but if the 5W-30 had been run for the same 5k miles as the 0W-20, wear would likely be the same. Likewise if the 0W-20 was ran for 3k miles, the wear would there again be the same as the 5W-30.
If you start at 0ppm Iron and have 7ppm by 3k miles, how much Iron do you have at 5k miles? Basic math.

Polaris Labs didn't flag any wear as abnormal or throw any cautions. Really, I wish I had sampled the 0W-20 at the same 6-month mark as the 5W-30. I believe the wear numbers would be toe-in-toe in a like per like comparison like that. Maybe next time? Currently, I'm testing out Pennzoil Platinum 5W-30. Maybe I'll test the 0W-20 version after that.
