I'm curious to see how many people are actually using Pre Lubers. This may have been discussed previously and I just missed it.

Anyone at all using them ?

3 years on my Accusump system, one plus of this system is that it allows you to run about a quart low in the pan.

If the oil system is designed correctly, there is no need to install an accusump system. After 50 years of engine building we have never used or needed one.

I'm using the Eickert kits. Basically a fuel pump that draws from the bottom of the pan. Besides pre lubbing I have a disconnect that allows me to change the oil with the boat in the water.

I had them on my boat and sold them .Ive never seen any probs from not having them.I just wouldnt rev a cold motor and let the oil pres come up first.

Maybe a oil heater in cold climates ,but then its to cold to boat anyway.

Still it's nice to have oil pressure before starting a motor that has sat for 3-4 months, yes?

I have preluber oil pumps from http://www.pre-luber.com/
I build 40-45 PSI of oil pressure before starting the engines.
Feels good, especially if the engines have been sitting for some time.
The pumps also make oil changes easy.

I'd say yes but only to a certain extent...

If the motor isn't turning over you will only be getting oil pressure to a couple journals and not very much up top... That's why you have to manually turn the motor over when you prime it for the first time. The rotating assembly holds most of the oil when the motor is shut down anyway.

I'm no scientist or engine guru but that's my opinion...

I think it's a little better than that, with the valve covers off you can see oil at the rockers after about 25-30 seconds. I would guess that most of the bearings should be seeing oil by that point with roughly 1 - 1 1/2 quarts of oil being pushed through the motor.

Preluber for the last 10yrs... Not needed, but it sure is handy for priming a motor that has sat for any lenght of time.
I use the preluber everytime I start the motor.. Maybe for the next ten I wont use it and see if it makes a diff.
I know a lot of guys dont, but I know of instances where they should have. Then of course we are a proud lot and most guys wont tell you when their stuff breaks..
