Engine/Transmission (1998.5 - 2002) Oil change Adding 15qts

[cmckinney]

What happens if you add more oil to the engine then is necessary? Should you see a higher oil pressure and can you go longer without an oil change?

No and no. I do not believe you will run higher oil pressure and putting more oil in than is called for will not let you go longer on changing the oil. If you put to much oil in it will cause your crank(don't remember the word its called)but anyway it splashes around to much. I am sure somebody will reply that can put it in better techincal terms. Sometimes the word is on the tip of my tongue but this brain don't work. Cavitate is the word I'm looking for I think.

Don't do it........

I have overfilled the crankcase a few times. You end up with low oil pressure and the oil is full of air bubbles. The crankshaft counter weights dip into it and mix air into the oil.

OVER-FILL ENGINE OIL??

What lschultz is trying to tell you is that you will screw your engine up. At least read your owners manuel. Gaw

With 15 quarts you might want to go and buy some new seals and gaskets, cause its probably going to blow out the tappet cover, valve cover gasket, gear cover and who knows what else.

This is a no no!

Oil pan is 9. 46 quarts capacity, filter about 1 quart, Engine passages probably another half quart +/-.

I have seen gassers die this way. NEVER overfill your oil pan, it will cause crankcase overpressureization and foaming of the oil.

Tell us this is a hypothetical question Like the others have said not good. Just a suggestion, read your owners manual and follow its direction. Since you are obviously into your truck (you joined the TDR) you should order a service manual for your truck. It has more detailed information. Problem is the more you learn the more questions you will have

And the more money you'll spend!

//////////////// Drain some out into clean container ////////// like now don't wait . Check with stick and refill if needed to proper level with recovered oil to proper level . Do not run Eng over full as stated by others. lol Ron Bissett in LOUISVILLE KYOo. Oo. Oo. Oo.

 

[cmckinney]

Well I did put to much in my truck. I will be sure to drain the extra oil out to be at 11 qts. I haven't noticed any problems or any strange noises so I don't think my engine gaskets have been blown.



I figured out why I thought 15 was correct. My brother was looking at the 7. 3L PSD and that's what they take. Not good... .

The password is..... Windage.



Like HEMI said, this causes the oil to become areated (foamy). Under pressure (in a lubricating film such as between the rod & main journals and the bearings) these bubbles implode and remove material from the bearing surface (cavitation). Not a good thing.

CM said"THATS WHAT THE PSD TAKES"

cm: The OTRs take up to 5 gallons Please don't try that.

What are OTR's??

 

[BV]

OTR

OTR = Over The Road or Semi or Tractor or Big Rig - As in Freightliner with a sleeper pulling triples.



Welcome to the TDR

Oh I see...



I guess they never sent me the official TDR anacronym book.

Bad Things Happen

Cavitation will definitely be a problem, but another problem I've witnessed, was a broken crank!!! It was not a Cummins engine, but an older gas International Harvester industrial engine. Could it happen in ours? Don't know, but I'd really hate to be the one that got to say that it does!!:--)

cmckinney,



Look here for the official TDR anacronym book:

I have heard up around 44 quarts fior the big "OTR" trucks

 

[Barnstormer]

My new 2001 HO was DELIVERED with about 15 qts. in the pan. Never had a problem.

Our trucks hold nearly three gallons of oil normally. Why in the XXXX would you want to put more?

I have had other brands of diesels. One of them wrote in the service manual about diesel run-away. This is when there is enough oil getting past the rings ( say from over filling) and the oil now burns as the fuel till the oil level falls low enough to make it stop getting past the rings. If you ever experience this :: you will not be able to stop your engine with the key. You will have to overload it by popping the clutch. This oil run-away is also a fear in our commercial diesel engines (Detroit 149s and MTU) The MTUs make 3450 horse power, I quiet frankly can't think of anyway to stop them once they are in run-away. Soooo, save some money and just put 11 quarts in. Why tempt fate?
