Oil Reservoir Tank

[Kevin Erion]

I removed mine on both the 99 and 01. I have never had to add oil between oil changes so what is the need?
This would be another story if I had an 8V92 or I was a paid driver going 15 to 20000 miles between oil changes.

Pete,

As far as I know, that's the original tank, and has a Prevost decal on the bottom.

I have also never had to add oil between changes.... but I like having that extra capacity just in case I need it some day.

I posted this to hopefully keep someone else from making such a bone-head mistake.

My guess is that most of the water entered the open tank when we had a 12" - 14" rainfall last December while I was in NJ, and of course we've had several smaller rain showers since then.

We never had to add oil between oil changes in our 1991 Marathon - 8V92 (probably because we changed the oil more then we needed), but I would always have the oil reservoir tank drained and re-filled with fresh oil when we had the oil changed.

Ditto on mine for the short time I have owned....did learn that the tank only holds about 9 qts rather than the 10 qts the manual states

I have the square tank seen in the upper right of the picture.

On the right side, toward the front of the tank is a glass view tube. It tells you the level of oil in the tank and would show if there are layers of other things like water in there. I am headed to the coach and will try to get a picture of that.

Checking that view tube has become a part of my standard checking. I want to make sure that the confidence I think I have because of carrying additional oil is justified. I never thought about it as getting contaminated before.

Here is the condition of the resevoir tank cap when I took possession of the coach and the reason I started always checking this. It does have a breather hole in the center of the cap.
