I wouldn't be using anything less than a good quality ester synthetic, I use Gulf Competition 10/40 usually, I'm currently on AeroShell but that's a whole other matter :p
With the heat and pressure Diesel engines are put under when making much more power than stock, you will shag bearings if you have crap oil...
Okay then, what would you recommend for a K14 at 26psi on a Bosch with govmod+ground lda running veg oil? Also, what is good oil protecting big blown XUDs from exactly? We know that a good oil won't prevent them from chucking rods, so is it just wear on the bores and valves that it is protecting against? Thanks.
