I just gotta testify...
1993 Plymouth Acclaim, 2.5l.
This car beats up oil badly. All the dino's I've tried look nasty after 2000 miles (to the eyes), and are consumed at about 2 qts/ 3000 miles or some even more!
I've had the Rotella syn in now for 4000 miles (the longest i've ever gone), and it still looks and smells good. Also, consumption is way down, and engine noise is much better. This may be a great oil for the price conscious synthetic user.
I will try in in my Nissan pickup for the nest change. It's a little noisy with Mobil 1, though the oil looks to be holding up well. Maybe the Rotella will quiet it a little.
