You hear/read 3 basic statements on just about every board:
1. I run synthetics, and it feels faster
2. I run dino
oil, and it runs fine
These statements are subjective, biased, and completly without merit to anyone who has a scientific bent.
3. I do periodic UOA's and I learned ......
This is where the money is. Facts and data, proof and disproof. The real deal. For example, I learned semi-
synthetic Mobile1 will not last 5,000 miles in my Harley. But Valvoline Blue dino
oil lasts a long time in my Cummins TD.
I pretty much ignore statements #1 and #2. But I pay carefull attention to #3.
