1st vehicle:
Stepdad's '08 Liberty 3.7L...broken in on the OEM dino for 3k, then switched to M-1 sliver cap 5w20 for 1st oil change interval of 6k. Time to change the oil soon and am considering 2 things:
1.) switching from 5w20 to 5w30. Any issue with this?
2.) switching from M-1 to a Pennsoil product but not sure which is best choice. PP or YB? He wants a 6k interval and 80% of driving is in-town.
3.) Would YB be the "smoother" choice since I read about many motors with syn engines not running as nice as on dino
4.) Pending a decision, would YB be okay foir 6k in town or is that the deciding factor and PP is much better for these OCI & conditions?
comments & answers please...refer to this as "vehicle A"
2nd vehicle:
G/F's G6 GXP 3.6L bought with 15k & 5w30 dino in crank case all its life so far. Currently 17k on the ticker and at at 18k it is time to change the oil. I have decided to put in a Pennsoil product and she would like to go 5 or 6k OCI, Keep in mind this GXP is a higher output engine, but dino was still FF:
1.) Would YB be the smoother choice or is PP better since it is a HP motor
2.) Should I run 10w30 or 5w30 in this vehicle?
3.) If I do run YB, can she go 5-6k on it 80% HWY driving
refer to this as vehicle B
comments & input please...sry this is so long but I need this info soon.
My intution is telling be to do PP 5w30 for 6k on vehicle A and PP 5w30 for 5k on vehcile B...
