10w30HD oil in a 6.0??????

[BLACK_PSTROKE]

i was at a speed lube to get my oil changed today. (im working out of town so i couldnt do it myself). and i tell the lady i need 15qts. of 15w40 rotella t. then she tells me they only put 14qts in a 6.0 because 15 will overfill it. has anyone else noticed that. because i havce always ran 15 and never noticed an overfill? but back on subject she tells me that i need to run 10w30hd oil during the winter months in a 6.0. is she correct about this because i have never heard of this.. or am i the A$$ for telling here she is retarded??

Think I ran 14 and change last time. Believe ford says 14.6 or 14.3. Check the owners manual is says exact capacities.

nobody got anything on this???

I always put in 4 of the big containers. I think there gallons, so 16 qts.

the filter takes at lease two qts. then the oil pan takes a lot

I know quite a few people who switch to 10-30 for the winter months. Im gonna give the 15-40 a try this year. My truck is always plugged in. I used to run 5-40 synthetic in winter months but its too expensive, IMO

15 quarts in my 6.0 puts it on the line. I do hear some colder states using 10W30 in diesels. Easier on the starter and quicker to move that oil. Ask your dealer what they use for winter months. Might wanna top off that 6.0 or at least check the level. jmo

Lots and lots of discussion on this over the years. Apparently, some trucks just take 15 quarts and some take 14 quarts. Just do NOT fill it past the full mark on the dipstick. 16 quarts is definitely too much. The oil can become aerated when too full and you will have problems in various places - injectors first I believe. Scheidt27 is pretty much right on. Synthetic is a good thing to run, but it can be expensive. Whether it is too expensive, that is a matter of personal choice. Just make sure the oil is CI4 plus or CJ4 rated.

i run 10-40 in the summer and 0-40 syn in the winter. we get pretty cold here though. you wont go wrong running 10-30 as long as it is CI4 or
CJ4 like was said.

FRom Here:
6.0 PowerStroke bulletins
6.0 Oil Recommendations:
Some trucks with the 6.0 may exhibit hard starting, rough running and lack of power in cold temperatures, particularly on a cold start. This may be due to the oil being to thick for the operating conditions. Ford is recommending to use the following oils for the listed operating temperature.


SAE 15W-40 is the preferred oil above 30 degrees, but it is acceptable for use down to 10 degrees, and is recommended for towing down to this temperature.
SAE 10W-30 is the preferred weight between -10 to 30 degrees.
SAE 5W-30 and 5W-40 is acceptable for use below 30 degrees, and 0W-30 is acceptable below zero.
(All temperatures are in Fahrenheit.)
The oil used should meet Ford's specification of WSS-M2C171-D or API CI-4 PLUS, CI-4/SL or DHD-1. CH-4 is acceptable for use if CI-4 PLUS is not available. TSB #05-16-6.
Keep in mind that CI-4 oil is designed for the increased soot contamination and higher coolant temperatures of cooled EGR systems on a diesel; CH-4 is not.
Nowhere does the TSB mention synthetic versus conventional oil recomendations or ranges.
Ford has not released anything recommending NOT to use a specific brand of oil.
