Highly unlikely. You can get additive clash, but base oils don't clash (as long as we're talking about synthetic and natural hydrocarbons, which we are in this case).
A 0W20 is way to thin to be running in a car that requires a 5W30,quote:

I switched my wife's Grand Am over to the PP 5w-30 after the last Auto-Rx cycle. Too early to tell much, but I'm sure it will do just fine. From everything I've heard, it's a very good oil.
I've got an '03 Focus ZTS that I had planned on running the 5w-20 PP in, but I went ahead and purchased some Schaeffer's instead. I figure since I'm running the PP in the Grand Am, I'll try Schaeffer's in my Focus.
Keep in mind Pennzoil has just introduced the PP in 0w-20. It's marketed as being for hybrids, but you could use it in the Focus if you wanted. Another option (now that PP is the only oil I'm aware of that comes in two different -20 weights) is to run the "thick" 5w-20 PP in the summertime, and the "thin" 0w-20 in the wintertime.
The reality is that either oil (Mobil 1 or Pennzoil Platinum) would work just fine in your Focus. I had run the 0w-20 Mobil 1 in my Focus a few years ago. It did fine, except that it did seem to make the engine a little bit noiser than other oils I've used. This seems to be a common "quirk" of M1, though, and may or may not be anything to worry about. Also, M1 no longer makes the 0w-20 grade, so you would have to settle for 5w-20 if you went the Mobil route.
Perhaps a phone call to Pennzoil with a description of what you used will tell us the answer to our questions. If you do so, please post their reply & ask for name verification of the person you're speaking with. No need to post their name here, but keep it somewhere for further reference.quote:

Here is a comment from the Pennzoil Platinum site:
It is Group III+, PAO, and ester according to Johnny:

Who said anything about running a 0w-20 in a 5w-30? The Focus (as well as other 2001 & newer Fords) recommends 5w-20. The weight of the oil has nothing to do with the noise I was referring to.
LOL, you're joking right?
