I read some independent lab test on a blended oil, and full synthetic and Oil Filters, and found that the synthetic oil has less friction all around, and is a cleaner oil. I also researched synthetic Oil filters and found that they hold back the dirt, metal that is flushed out by the synthetic oils.

* Did you know that there are engine oils on the shelf that can harm your engine?
* Did you know that there are codes on the bottle that tell which oils protect and which could harm your engine?
* Do you know where to find these codes?
The American Petroleum Institute (API) knows, as do the engine builders, and the oil companies.
Oil Filters:
The good synthetic Oil filters have a reinforced polymer mesh for holding engine dirt, and a silicone anit-drain back valve for long life and protection against dry starts. So, I did a search and it looked like Royal Purple, Mobil1, and PurolatorBoss Synthetic Oil filters were the best when compared online, not in that order.
Now on my experience with a Royal Purple Oil Filter:
I first chose to use a Royal Purple Oil Filter, 10-48, on my last oil change with Mobil 1 Full Synthetic 5w-20. The Royal Purple Oil Filter leaked, so I took my RAM back to the place that changed my oil and they cleaned the filter, and mounting area and tightened as tight as it would go, and it leaked again, about 1 quart total while sitting in my driveway. I didn't want to ruin my motor, so I just replaced the RP filter with a PurolatorBoss PBL12222 and no leaks. In my Opinion RP is NOT all it's cracked up to be.
Oil Pressure w/Full Synthetic oil and PurolatorBoss 34 psi with engine temp 190` and at an idle, and when driving around town 50 to 53+ psi, depending on how many rpms the motor is turning.
I should post a picture of my driveway where the oil leaked.
