AMS-Oiler preluber

[RDHamill]

Has anyone seen or heard any detailer about the new AMS-Oiler?

Looks to me like this rig makes oil presure prior to start up.

I'd think that would be great for a CTD, the timing circiut for the pre heater is in place, why not prelube at the same time.

Can't wait for details.

Don't see it on Amsoil's web site as of yet.



any thoughts ???????

That looks like a slick setup RD. For someone who totally believes a preluber on a Cummins is a waste of money, this setup may be worth looking at. It's certainly better than the type which operate on electric motors and plumbing which is guaranteed to fail and cause more harm than good to your engine. I like the way this one is incorporated in the bypass system and doesn't require additional hoses/plumbing.



The concept of pre-lubrication based on a oil pressure reservoir generated by the engine's own lube system has been around for awhile, certainly isn't anything new.

Why is it that you think a prelube on a cummins is a waste?

I'm thinking that the intial investment might only have a payout after the "normal, nonpreluber" life of the engine.

which could be 500,000 miles or so.

My other thought is sort of like my thoughts of a bedliner... who am I saving it for?? yet I have one !!!



and what might I ask is a whiplash shifter ????? I might need one and not know it yet



thanks for the input

I think pre-lubers are a good idea, but this one is a total waste of money. I don't think 160cc or about 6 ounces of oil will go very far on a cummins. The $400 price tag is waaaaaay too high. I think this is an attempt by amsoil to solve the drain back problems caused by people mounting a dual remote filter by the battery. You just can believe everything amsoil tells you.



I don't understand why someone would mount amsoil's dual bypass two feet above the original filter location. Any good the bypass filter might do is offset by the engine running 3-5 seconds longer at start up with any oil pressure.



If you want a pre luber morso makes an accumulator (proper name for one with out a pump) that holds 3 qts. Costs $175 for accumulator + $100 for the electric valve. (prices from summit racing)

Also if you run an accumulator you need to have it on a separate switch. Not on the ignition switch like amsoil recommends. Other wise when you start the engine the accumulator gets filled first instead of pumping the oil through the engine.

I wonder if the oil in the Amsoiler would show on the oil presure guage just prior to start up.

And how much presure would be the difference between and lubed start and a dry start??

As a matter of fact, I have my dual remote mounted below the level of the factory filter just for the reason you speak of, it does not drain on shut down.

I'd be intested to know if the Amsoiler has a way to prevent the first shot of oil presure at start up from filling the AMsoiler, and lets it go to the engine instead??And then refills itself after a delay?



great question, thanks for the input guys

LOL RD, why did I know you'd say that?



OK since you ASKED here's my little 2-cent opinion. . .



Prelubers help get oil to your bearings before you light off. They don't give you that much oil pressure, so it's mainly they're providing oil circulation at startup. Well unless you've been parked for months you're going to have a film of oil on everything anyway. And you don't need oil under pressure to provide protection. Oil pressure is mostly needed to circulate oil so it can carry heat and contaminants away from the part, not so much to create the oil film needed for good lubrication.



Most initial startup wear probably occurs around the pistons and rings, which a preluber does nothing for (engine has to be running to get oil up here).



Another thing, back to the oil pressure subject, once you fire off your engine and it's running, the accumulator is taking oil pressure away from your system so it can recharge itself. So basically there is no free lunch here.



Since Cummins engines last so long, it's usually non-lubricaton related problems that ultimately do them in. Leaky or blown headgaskets, killer dowel pins, runaways from bad turbos, damage from blown turbos, meltdowns from excessive EGTs, injector failures damaging pistons, cracked #53 blocks, etc. Not inadequate lubrication at startup. So the moral of the story is it's definitly a waste to put a preluber on a #53 block (ok just kidding on that one



Well anyway since you asked, I shared

I'm glad you did, that's basicly what I thought you'd say.

So if you made the investment in the AMSOILER , and it did it's thing, most likely the death of the engine or truck would still be a rusty body, rusty frame or engine problem such as those you mentioned and not bearing failure.

But on the other hand , it would never hurt anything either.

thanks for your thoughts.

Here is a cheaper option that does the same thing. I personally do a lot of parts running in town so I get lots of starts most days. I think one of these might be a benefit to me but who really knows. These engines go a long time even when abused. I like the idea of a preluber but not sure if I will ever get one or not.

We have Peterbilt trucks with N-14 Cummins engines with over two million miles on them that have never seen a pre oiler. I know of a series 60 Detroit with the hone marks still in the liners at over one million miles. The rings were replaced at 1,012,000. Clean oil is where you get the long engine life. It would be nice to have an oiler that keeps pumping oil to the turbo until it cools down a little after shut down. They might be a good idea for engines that are shut down for long periods of time such as marine engines.

Most engines don't get shut down long enough for the oil to drain off the parts. I have one diesel that gets used about once a year. I'll bet there is always oil in the rings and bearings. You can get gadget overload.
