penzoil longlife Gold? 15w40 mine also switched on this oil for recent work on the engine...As you know my VR running Pennzoil HDEO 15w-40. Suppose to change every 6 months since very low mileage, Recently was busy so push to 8 months since mileage only 1k plus km, but after change can feel the smoothness of the engine......lol
seems like working exactly the same as my previous 20w50 of castrol CRB multi....
if my engine totally no leaks afterwards will opted for penrite HPR racing oil later....with no leaks...definately would waste a good oil..
