Hey 4.3 You mentioned to me how that you have used Vavoline VR1 I am wondering can I find this oil in 10w30. and if it is available in this wieght I was thinking about using it as a break-in oil. I found some imfo on the internet that the VR1 oil's have a very high amount of the Zinc& Phosphorus that these flat tappet valve train's must have for break-in.
