Have been using Delvac MX 15w40 in the marine volvo penta v8 for two summers now. The manual calls for 15w50 mineral or 30 synthetic but I have had good results with the 15w40, good pressure and clean looking oil changes.
Now I found a deal on PENNZOIL GT PERFORM 20W-50 and thinking that may be closer viscosity wise, but I don't know much about pennzoil. What kind of oil is this? Should I switch?
Mobil Delvac MX 15w40 OR Pennzoil GT Perf 20w50?

NO stick with delvac
Even if the engine is petrol, stick with the Delvac. It is likely a heavier duty oil.

Hi,
lars11 - you are using a very very good lubricant - stay with it

Looks like a good oil anybody know where one could get it in the states? would like to try a jug or two?
I searched for Delvac MX a few months ago. I could not find it at any truck stops or diesel garages. I finally called Mobil, and they said it is only available at distributors. I found a distributor in Grand Rapids that had it at $15/gallon. If you get on Mobil's website, I'm sure you can find a distributor in your area.

Seems the consensus is to use the HDEO (Mobil) and I agree. While Pennzoil is also top tier oil, isn't this oil more tailored as a "race oil" with limited detergents in its add pack?
