In terms of engine cleanliness, wear and protection when is a HDEO not better than a good PCMO?
I'm looking at HDEOs for my own diesel Ford Focus and seen a few 10w30 syntethic oils which would go nicely in my car, my partners VW Polo and my Mothers Suzuki Jimny. I could probably throw it in my Fathers Defender 300tdi and BMW F30 320d too, although the Defender usually calls for something thicker.
And... it got me thinking.
If you took emissions and fuel economy out of the equation and you were looking specifically for engine longevity, would you consider anything other than a HDEO? Is there anything a HDEO isn't good at?
