I use Castrol gtx high mileage in my dad's Ranger and my civic. 223k and 173k miles respectively. Synthetic blend.

The oil uses magnetic particles to adhere better to critical surfaces.

No it doesn't you gimp. It's called marketing. And you are the lowest common denominator they are marketing it to.

Mobil-1 0W-40 Euro formula because it meets MB Spec 229.5, and I can get it at Wal-Mart for about $24/5 qt.
