How much oil is everyone using????

[WyattEarp]

so the new trucks take more, mine with a pre filter fill only takes 11qts and that sits her on full mark.

Is it because they went to a deeper oil pan or was it the change over to the 600cummins.

I have an 05 and the last four oil changes I have done, I poured a total of 3 gallon including the filter. Everytime I check it, cold or warm, it reads full. I love it though, makes oil changes a breeze. No guessing.

I almost wonder if the dipstick (the one in the truck, not me) is marked incorrectly.

Maybe not so much the dipstick itself, but perhaps the tube where it meets the block is not seated all the way in. IIRC, earlier trucks had this "problem", I do believe it was covered here way back when here. Think about it, all it needs to do is be pulled out 3/4" or so and bingo, a "low" reading on the ol

dipstick.

Mines the same as the previous posts. I install a new filter, (I don't pre-fill the filter) throw in 12 quarts, fire it up and oil level is right at the top of the safe zone.

You may want to rethink the prefill trick. Lot of things written about prefill on this TDR.

I'd look in the manual and see what that says. As far as I knew it's 12qts with dry filter for all the engines... . though our motor pool on base did some oil changes on our trucks and one has 13qts written on the fan shroud, and the other 15 qts...

2005... . 12 quarts of oil.

I had a 91. 5 that had a badly calibrated dipstick. It took 13. 5 quarts to the full line. I called Cummins and they checked my engine serial number and oil pan size and said the engine should only hold 12 quarts. I never added more than 12 after that and it fixed excessive oil going out the breather, etc. It only took about five minutes on the telephone with Cummins to get the correct oil quantity which happened to be the amount called for in the owners manual.

04. 5 600 CTD... with new filter, 12 qts fills it to the top. It sounds like some of you have short dip sticks (have your wife check ) or long dip stick tubes. Believe the 12 quart spec, not the dip stick.



I use Delo 15w-40 and Stratapore.

 

[smartineau]

12 quarts with a filter change.



Hearing the horror stories here about the wrong weight of oil, too much oil, and such, is just that much more proof for me that I will continue to change my own oil.



When something goes wrong I only have myself to blame.

i just did my oil change on my 05 and when i finished and checked my dipstick after letting it sit for about an hour and a half it was in the middle of the safe mark. I was gonna go and buy some more oil the next day. But the next day i checked it again just to make sure and what do you know my oil was all the way at the top of the line, it was full. My suggestion is to check it the next day before adding anymore oil. I have done 3 oil changes on it now and this was the first time that it read below the full mark. And i always put 12 qrts in, never have i put more in.

I believe the manual states the best time to check the oil is after sitting overnight.

 

[Diesel Nut]

12 Quarts of Amsoil and she's full and happy.

 

[jwduke]

I use 12 qts. of Mobil Delvac 1300 & a Stratapore. Full right to the top of the mark.

Yes, I have read alot on here about pre-filling vs not pre-filling an oil filter. Both camps believe strongly, kinda like engine oil preferences, and there are good arguments both ways. The logical side of my brain says it has to be better to pre-fill the filter because oil is delivered more quickly to the moving parts. How much quicker, and how much it reduces engine wear I really never could resolve in my mind. The oil filters on my tractors are inverted, so all the oil drains back to the crank when they aren't running, so they always start up on an empty oil filter. I just decided that the extra potential mess of pre-filling wasn't worth the potential extra engine life I might get... . if it's even measurable or if I have the truck long enough to see the end result. However, even though I don't do it, I agree with you and I think pre-filling is a good practice to get into. A little off subject, sorry!



PS. I use 12 quarts Rotella T and Stratpore filters approx every 5,000 miles.

 

[robert4570]

Just did my 05' CTD ,12 QTS prefilled the filter and dumped the rest in the motor .



So the tribe has spoken... ... we all agree on 12 qts U. S.

Haven't done the metric conversion yet .

 

[TCluff]

i have to agree with everybody elses 12 quarts, i usually just prefill the filter, then dump the rest in the engine, full every time, the only time i ever overfill is when when i prefill the filter with something else like an additive which i dont use very often, and a full quart is not enough to cause any proven harm, also 12 quarts at 180 degrees is going to read fuller than 12 quarts at ambient temp, so keep it in the safe zone and you wont have any problems

just my . 02 cents, FLEET GUARD FLEET GUARD FLEET GUARD, anything else could void a warranty in an engine failure.....

That is just CRAZY - TALK!

FRAM® Extra Guard® oil filters are the number one choice in oil filters among consumers.



Oil that lubricates and cools the engine is picked up by the engine's oil pump, cleaned by the oil filter, and reused. It is vital that any dirt or contamination picked up by the circulating oil be removed before it is pumped back into the engine.



Tiny dirt particles between 10 and 20 microns do much of the damage to bearings, cylinders and other moving engine parts by rubbing and causing wear.



How Does It Work?



FRAM Extra Guard filter uses a thick, multi-fiber media and provides a maze to trap contaminants effectively.



Before oil enters the engine lubrication system, it passes through the oil filter. The filter's job is to remove potentially engine-damaging dirt particles.



To provide the best engine protection, the maximum amount of dirt should be removed the first time the dirt passes through the filter before it reaches the engine.



The Society of Automotive Engineers approved an industry standard test called the “Single Pass Efficiency Test” (SPE) to measure a filter's ability to remove contaminants from the engine’s system. The SPE Test is one of the industry standards for evaluating and comparing oil filter performance, and measures a filter's ability to remove less than 20 micron-sized particles of dirt the first time through.



The FRAM Extra Guard filter performs at 96. 2% efficiency in the single-pass efficiency tests.



And like the FRAM® Tough Guard oil filter, the Extra Guard filter features our advanced synthetic glass and cellulose media, which is a combination of synthetic glass and cellulose uniquely formulated for top-rated efficiency for the life of the filter.



The Honeywell Consumer Products Group warranty policy also protects the consumer if it is determined that a FRAM filter is responsible for damage to an engine due to defects in design or workmanship.



So you see, you just can beat a FRAAAMMMM!

Thank you for that. That is a good argument, but I'm going to stick to prefill. The most dangerous part of prefill is to get a piece of the oil container seal into the filter.

I'm with you Grizzly -- I prefill my FRAM filter every oil change.
