.....using the new Mobil 1 0W-20 Super Synthetic motor oil this winter? I'm driving an 02' F150 with a 5.4L engine. With 15K on the motor, I currently have a slight valve tap at start-up(2 or 3 seconds), could this application help with the cold winter starts?
I'm currently using M1 5W-30(summer) and ONLY hear the tap in the AM, NEVER during the day. At normal operating temp's this motor purrs.
Anyone hear of Schaeffers #132 oil additive?, would it help?

 

It should help with starting since it is thinner...
