5w30 Pennzoil Full Synthetic and a motorcraft filter on my 2001 f150 5.4L
I run it in my 2003 ford escape. I live in Sunny California so the season do not change enough to change the weight of my oil. The ONLY plus to living in California.

Castrol Edge and K&N Filter. Runs great!

Are you aware that Mobil One in 5w-30 has been failing the IVA testing for almost a year now? Cam wear will be increased and engine life shortened. If you're a Mobil fan use the EP version. There is no such thing as a Full Synthetic. All of the synthetics will use a mineral binder of some sort to make the additive package work with the basestock. Mobil One is a GP III dino based oil with a splash of Super Syn, an ultra high VI PAO.

My God... I have used Mobil 1 Synthetic last 4 oil changes or so. This is scary reading this.

I guess I will go get it changed immediately.

Yeah, switch to Castrol Edge or at least the GTX Dino stuff.
