dwg86 wroteI think Brad Penn has a high zinc break in oil. I am going to use Valvoline ZR1 after break in. Valvoline ZR1 racing oil has 1400 zinc and 1300 phos. You can get it in 10w30. Most racing oils don't have detergents in them, because oils are changed so much. I called Valvoline tech. They said the VR1 has detergents and is good for 3000 mile oil changes. Most autopart stores carry the VR1 20w50 (autismzone, advance, etc) for $3.89/quart. The only place I could find the 10w30 was Napa, and a small Mom and Pop auto part store in my town... $4.59/quart.
the local machine shop I go to here stocks 4 pallets of brad penn grade 1 oil all the time. says it's got all the old additives that the newer oil pulled out... other option is the oil additives.. but that's dicey.. you can order cases of brad penn oil online as well..
