That pre luber is a pretty slick setup.
It is very slick, I think also. It is a brand I hadn't seen before but came up on a Google search when I looked for a current preluber example.
The only thing that has been a downside to the accumulator type units in the past was that it takes two of them if you also want to post lube the turbo to prevent the infamous coking up of the bearings. With the water cooled units everybody uses now, that really isn't an issue any more as the systems, if well designed will gravity flow the engine coolant through the bearing housing after shutoff so it stays well below coking temps.
Of course, as I mentioned earlier, it really isn't all that good to stop any engine, gas or diesel, turbo or not, immediately after a very hard pull as a lot of the parts will be very hot at that time so a bit of oil cooling on them can prolong life.
I have considered putting an accumulator type on our 07 Chevy Roadtrek and that unit in the link may convince me to actually do it, as it looks very well done.
As a reference point of benefits of prelubing, although it is a single data point so far from conclusive, after I had a pump type on my 600hp twin turbo 340CID 1970 Dodge Challenger a few years, I ran a test on a new 1992 Ford Escort wagon I had just bought for commuting. I had worked with the preluber company quite a bit on the Challenger best practices installation so had contact with one of the designers there and called him and asked if he wanted me to test a preluber on the Escort over full engine life. He did want me to and I got a unit for their cost and put it on when the car was just barely past breakin.
That old Escort was around for 18.5 years and 210K miles of Minnesota cold weather commuting before the it rusted in half so bad it got dangerous and broke the rear brake lines. I quit changing the oil at 200K miles as I knew the time left was pretty short. It went the last 10K without needing oil added and it still was pretty clean even. It had no lifter ticks at any rpm or temperature, even -20*F starts, and had never had any repairs on the engine at all, not even a valve cover gasket. Timing belts and water pumps as preventive were done.
The luber company was out of business or bought out by the time the Escort died, but I did tear down the engine anyway for my own curiosity after checking the compression on it, which checked at high mid of range and very even between cylinders. All the oil related parts checked nearly new for dimensions and surface finish, crank, bearing clearance, lifters, valve guides, camshaft, oil pump. Cylinders had less than .001" taper and out of round. I was very surprised that a short trip, cold weather, commuter, small, engine would check that well. That engine, if continued on the prelube pump, probably would have gone near 400K, best guess, unless it had a metal fatigue failure. It was run the whole time on off the shelf dino oil at 10-30 in the summer and 5-20 in the winter.
