What's your reasoning behind running it? Reason I ask is I have ran it in mine as do a lot of diesel owners and to me it doesn't make $cents$. If you don't sample it and run the oil 10k miles or more you don't get your moneys worth out of it. Mobil 1 and Chevron Delo both are very good oils and are readily available synthetics. If your just looking for better protection within OE change intervals I would go this route with a GM filter
