I agree with both previous posts - however, the above-mentioned oil is so much more expensive than the Chevron and Shell Diesel oils specifically formulated for TURBODIESEL service that you would need to run the KJ like an over-the-road 18-wheeler to equitably amortize the cost\mile
- 18-wheelers accumulate immensely greater mileage between changes because those miles do not include the continual stop'n'go conditions of the daily commute, and grocery runs, and school drop-off and pick-up, and all the short-tripping a passenger SUV endures between idle and low-speed operation on a day-to-week-to-month-to-year-to-decade (and century, eh) basis
Long-term over-the-road miles serve to burn-off the pollutants and contaminants that passenger-service engines regularly accumulate during normal stop'n'go operation
Turbo gasoline-fueled ratings are for less-harsh conditions, but were combined with the turboDiesel ratings because the turboDiesel-rated CI-4, CH-4, CG-4 oils for harsher conditions were more easily-available everywhere than those SJ-SL oils for turbo gasoline-only service
But, do not use any oil rated less than CI-4, CH-4, CG-4, formulated to survive passage thru the turbo center-cartridge at temperatures up to 1200*F and above
- not even to mention the oil-sprayed piston under-crowns required to reduce turbocharged crown temperatures
Some synthetics are rated for higher temps than that, with increased cost, but with avantage of, being lower viscosity but with increased lubricity, require less 'overhead' losses - 'nuther words, less over-all bearing\piston\camshaft friction and crankshaft rotational impedance improves power output
I used RPM DELO for a while, years ago, but it goes in dark and comes out darker, so I switched to SHELL ROTELLA because it goes in golden clear and slowly darkens during the first week, allowing me to compare for any worsening condition of the combustion process
