Anyone here using one of these pre-oiler's on their rig?: http://www.autoenginelube.com/ A co-worker of mine has one on his 98 Cummin's, and thinks it's the next best thing to sliced bread. Just wanted to get some other opinions on these pre-oiler's.

 

I also am seriosly thinking of getting one. Cummins says over 70 percent of engine wear occurs on the first few revs of the engine waiting for the oil to arrive where it is needed. on the forums some of the guys have put a switch on the fuel solenoid to allow engine to build oil pressure to build before allowing fuel to the pump. End result is good and cost is very low. I think it would cause additional wear on a $300 starter.

 

I think its a good idea. It makes sense to have one to me. Its not that expensive and it can save alot of wear on the engine. Not that these engines don't last for a long time but why not make them last longer.

 

Startup wear is a universal concept in any type of internal combustion engine. 70%? Sure why not, but 70% of what? I heard somewhere 70% of all statistics are calculated to support the pre-concvieved notion in question.

Engine wear occurs in barely measuarable amounts over long periods of time in normally operating equipment. Everything from the type of oil used, how that oil is maintained, to the way you run it and where it lives has a "bearing" on this. Here's what to consider if you are worried about startup wear:

If you live in Alaska and start the engine 10 times a day year round, it will last about half as long as if you live in Texas doing the same thing. Lower temps cause the oil to flow slower, adding to startup wear.

Hot shot's engine driving all day most of the time, will last much longer in terms of overall mileage than the typical daily driver, assuming the same equally good maintenance. Hot shot gives his engine one startup for at least every two or three seen by the commuter.

So, a pre oiler "may" not be a bad idea, depending on how and where you run the engine. Personally, if I thought I needed one, I think I could put it together from sperate parts for less than half the cost of the stuff listed on that page. The easiest most sensible way to get better startup protection is just use a 5w40 synthetic oil, especially in cold climates.

 

All,
Thanks for the feedback on the pre-oiler. Ace, yeah - I don't think it would be that hard to build your own. I am searching the web to see if anyone has done so, and is willing to offer up a parts listing.
