well yesterday i used 20w50 royal purple fully synthetic and a k&n filter. i have used filters before and they work great. thanks tho
If your motor is in good shape, using a 20W50 could be harmful to the motor under normal street use; instead use a 5W30 or a 10W30. However under extreme hot conditions, a 20W50 would be OK to use.

I've been using Mobil-1 10W30 along with Purolator oil filters for many years with great success. Like others are saying, change the oil filter every 3,000 mi.
