Ok checking my engine oil today, I needed to add 1/2 qt. The only way I could do this was by lifting the bed and topping it up via the filler cap ?Then I have to close the bed, start the engine and recheck the oil level outside. Luckily I put the right amount in the first time. But is there any way you can top off the oil via the dip stick tube? Or a modification I can do to stop the laborious task of in and out and raising the bed?I can top off the transmission via the dip stick. which is a lot easier.My coach is a 1992 Gulf Stream DP with a 5.9 Cummins and the radiator transmission cooler are at the back so vision of the engine is restricted.Appreciate any advise from others whom have over come the problem.Thank you

Our 5.9 has a gravity oil fill located on the front (rear, fan side) of engine gear case. It has a hose connection that goes to a fill tube that fills just above the dip stick tube. It is quite high in the rear engine bay which makes it hard to pour oil from a bottle, I have to use a flexible looong reach funnel in able to empty a oil bottle that way.

I certainly wouldn't worry about a quart low on a 5 or 6 quart gas engine. I'm sure your oil capacity is well over that and no need to worry about it even down 2 quarts. That's the reason they have ok range on the dip stick. If it's down to the add oil point it's sure lower than 1/2 quart.

Yaj, Thanks will look into getting a flex tube + Funnel, it will certainly help.And I 'd rather it take a little time than have the bed fall on me.... or would that be classed as sleeping on the Job ??Deereone, As stated its a DP = Diesel Pusher, and I disagree Oil level is important not only for lubrication but it is part of the cooling system. Plus the engine takes 19 quarts, that a mount is for a reason !!

Would guess your oil capacity on the 5.9 Cummins would be 16 qts. Seems to be about the average. 1/2 qt low , no need to add until the add mark.Good luckDave M

I don't know much about Cummins engines! I do know that CAT diesel engines you can fill 1 gallon above the full mark. Before I retired from work we had some people from CAT come to our shop at work and they recommended that we overfill by one gallon. All the CAT people were at our shop to investigate lower bearing issues! I don't know if you can do this with Cummins, might be worth looking into!
