Kirby i would say if you are running a turbocharged rig or a high
tollerance engine it will stun you how clean the oil will stay longer
than before. I used to have an 88 t-bird turbocoupe that i had
chassis dynoed at 500hp now this engine was highly modified as
you see but the first mod i made on it was an esslinger pre luber
system all other mods came after pre lube mod & never had an
oil related failuer on this engine or any other that have made this mod to i currently have 2 one on my 96 continental 2nd one on my 98 eddie bauer expy 5.4 4x2. To me it is beynod piece of mind. turbo ted

I put an Accusump pre-luber in my 2001 F150, because I believe most wear occurs at start up. It is basically a small captive air tank, like on a well water system, with a solenoid valve. I think it will be very reliable. It is actually made for racers, to prevent any possibility of oil starvation.
On a previous vehicle (supercharged Buick), I installed a different style, which used a small electric pump. Unfortunately, the pump seal, and then the pump motor, failed after about 60,000 miles. I never did replace it. I still have that car and after 265,000 miles, the engine seems like new, but its hard to say that's due to the pre-luber.
Like the religious use of synthetic oil, I doubt that many people will use their trucks long and hard enough to notice the difference (particularly if they're paying to have it done), but I think it is practical for some of us.

As MrBSS described, I meant to ask about experiences in adding a separate booster oiling system, for use before the engine starts. It reduces "dry-start wear" on the bearings (about 60% of engine wear) but does not alleviate wear on the rings or bores, on initial startup. Stationary and marine engines commonly use such a device but people haven't been interested in automotive applications. The truck makers wouldn't want to hear of it because it makes the engine last longer than average. I'm still thinking but probably will go for the hydraulic pump approach. Kirby

Boy a hydraulic pump makes a LOT of pressure. The oil system only runs 100 PSI at most. I to am looking for a system, but for both start up and shut down on a turbochaged 6.0L Deisel. Searched as many ways as I could think of, and can't find any old threads. Anybody got some names of electrically operated units that could run both before and after, which they have had good luck with???
Thanks,

Some do; some do not. All you need is a 12v oil resistant pump. If you can get its pump curve, you will be able to tell if the pressure and volume is appropriate. I guess I would try to get a magnetically coupled one, rather than having to deal with shaft seals. You also need a relay with a time delay. Sorry, I can't spend the time to explore this further.

I put together a homemade pre-luber. I found a 12V sealed positive displacement pump/motor and made up hydraulic lines from the oil pan to pump and then to back of the block (460)where the oil pressure sender sits. I relay and spring toggle switch allows cranking the preluber until oil pressure shows on the gauge. It's amazing how long it takes to show pressure if your vehicle has sat for a while. Some good sources for sealed motr/pumps are heavy equipment suppliers, lawn tractor suppliers etc.
I've run this for years now without a problem, I may get ambitious and get a circuit made to start it both before and after but the bulk of the wear is now looked after.
