Jake, why is it so difficult to obtain technical data sheets for Gibbs products like the DT40 that list info like ZDDP levels? I really think more people would consider using the DT 40 is they had some data to compare it against Mobil 1 and other brands.

And is there any information available yet on the "improved" DT40 you mentioned some time back?

Even the boutique products like Joe Gibbs Racing state they have “high ZDDP levels”, but do seem to publish any information on the actual numbers.

It is getting to be like some sort of well kept secret…………………

Jeff, I think you answered your own question earlier.

Hey Jeff, when I asked Jake about this last year, his response was some time in late 2013. See Chuck W's response in post #12 above .

I have thought that I would use M1 5W50 (April - Sept) as warm weather oil
M1 0W40 (Oct - March) for cold weather.
Car came from dealer, oct 2012 with new M1 0W40 + filter

Just run the Mobil 5W50 year round. Unless you live in the artic tundra. Keeps it simpler for you and less waste. The 5W50 is a little hard to find, but the internet makes it possible to find.
