Thanks guys!

My oil cap say "Castrol Recommended" and the manual says 5w-30 so I made the assumption that Castrol Syntec 5w-30 was fine. Knowing that most guys like M1, as opposed to Castrol, I made another assumption that using M1 5w-30 was a better choice. I was unaware there was a different model for Walmart, as opposed to a european or German-made formula.

A quick look at the referred website shows that Mobil 1 0W-40 is an approved LL-01 oil. Not wanting to make the same mistake, should I be looking for a specific european formula of this oil, something I can only get at a dealer or specialty store, or can I use the M1 0W-40 I find at a local auto store or Walmart?

I had no idea there was a difference between the "American" version and the Europen version of an oil by the same name. Thanks for clarifying!

On a last note, does anyone think that using M1 5w-30 for the last 20,000 miles has done any damage?
