I am planning on adding an oil accumulator to my truck and wanted to know if anyone here had experience with them. I was looking at the Moroso, Canton and MasterLube models.

I think it's a good idea since I will mainly drive the truck on the weekends and don't like the idea of the dry-starts.

Appreciate your thoughts.

 

I've had the same concern, because at times it has sat for a couple months between runs. I pulled my oil pan after such a long time to measure bearing clearance, and there was plenty of oil on the bearings. Still, it can't hurt!

 

They're commonly used on race cars to prevent starvation in corners when you don't have a very good oil pan. Most also use them to prelube before starting. If I was going to use one, I'd go with the electric switch model, so you can mount it in the engine compartment, and actuate it from the cab. If you use the manual, ball valve type, you either have to mount it in the cab (braided lines)where you can reach it, or in the engine compartment where it will be a PITA and you'll tire of raising the hood before starting the engine.

 

I wonder about the actual value of pre-oilers.

I have 170,000 miles on my 6.5L 94 Suburban (which I bought new 14 years ago)

I start it "dry" every time I start it. It hasn't failed yet. Big stationary standby generators are started dry every time sometimes once a week or even once a month. They last thousands of hours.

The bearings are not really "dry"


I think you might be worried about something that is really NOT a problem in todays engines.

But is it still a problem in yesterday's engines?

 

IMHO, Todays engines include "yesterdays" engines. I know of a lot of "old" engines that went many years and miles without pre-oiling.....they even did it with minimal oil changes....

If it was such a problem the auto manufacturers would have added accumulators a long time ago.

The only people who think you need accumulators and pre-oilers (and oil additives for that matter) are the people that sell them. That should tell us all something......

 

As a person with a 2002 V10 that makes tapping noises when it starts I intend to install an accumulator and hope for the best. What I would like to know is how to determine the size. One company offers 1 to 6 qt units but doesn't say why you would buy one rather than another except for the room available for installation.

 

This is a pretty old thread.....


I also think you're worried about something that isn't hurting a thing and you're going to spend a bunch of money for nothing.

I once had a Mustang with a 289 (150,000 miles) that the rod bearings rattled every time I started it! When the oil pressure came up it quieted right down!


It never seemed to hurt it at all.


You may have lifters that are leaking down and are "tapping" until the pressure comes up. That doesn't hurt anything either


My VW diesel does the same thing.
