There are those who use WalMart TC3 2-stroke oil in HPCR engines. A small amount. I've tried it and saw no FE improvement. So that is not the reason to use it, but fir supposed lubricity improvement.

I use Power Service pretty much all the time. And buy Shell of Exxon diesel. The combo is worth close to 1-mpg highway versus straight diesel.

And it's Unicorn as there are not genuine studies advocating this. In the days of mechanical, low pressure diesels one could burn oils fairly easily while on the highway and under a load.

Today, there's no smarts in threatening expensive injectors. About $4000 with installation and associated part replace by for six on my Cummins.
