Use what you like. but the biggest factor is a quality filter. There are definitely performance differences between filter manufacturers.

The biggest mistake I see when it comes to synthetic oils is people who buy some of the hydro-cracked dino oils labeled as "synthetics". Granted Hydro cracked dino is very very good oil but it is still dino. The primary advantage of full synthetic oil is it's ability to resist burning off in the high temp areas of the engine ( piston ring area ). This means better protection and lower oil consumption especially as the oil ages.
