dvldoc, what do you think of the spec of this oil?

That is excellent oil, it's almost the same as Mobil Delvac 1300, I'm talking almost exactly the same. Has a bit more moly and just a bit more Zinc. TBN for the Delvac 1300 is 10.5. The Viscosity Index is only 1 point less than the mobil Delvac is 137. cSt * 100ºC of Delvac is 15, and * 40C is 114. It looks like it is just a notch above Delvac but not by much and that is saying a lot because that is some of the best oil out there.


Plus it seems it's hard to find CJ-4 oil there, I'd use it in a heart beat. What brand is that and how much so every can know. This oil seems closer to CJ-4 Plus.
