Oil with zinc ?

Brad Penn all the way. And you know your buying oil from the USA Bradford Pennsilvania! Nothing better, best oil and best location.

 

I used the shell Rotella for years but found out that there zinc levels have been decreasing over time. Be careful!

ZDDPlus is sold by an Alliance Vendor here - support the HAMB. Add it to off the shelf oil - I saw Peak brand oil at Big Lots for less tha $4/qt - hey, Danica likes the Peak brand.
