Message	Not an issue for me... I run it in my 240Z turbo as well, which is why the extra additive. Most modern oils are not recommended for the L-series valvetrain. Lots of sliding friction there, especially with more aggressive cam profiles. I did use Brad Penn in the 240 for years but no longer available locally. I dump a bottle into a 5 Gal paint of oil, so not too much of an additive package increase. There was some concern that T6 had a change a couple years ago, but virgin analysis shows no change in antiwear levels. It seems to perform a bit better than Mobil 1 (shear) over the long term when the engine sees hard use. Frequently on sale for $125 Cdn and a $30 rebate per pail, so cheap for what it is. I use 3-4 pails per year.
