Hey how long are y'all going between oil changes with synthetic oil such as Amsoil ???
with the proper fill level and a quality oil they do not seem to use a dropNice post power struck !!
How many quarts do the 6.7 drink ona change ?
wait for the truck to tell you when to change it. also i have been testing a product called X1-R with factory fluids. add it to engine, trans, power steering, diffs, A/C and transfer case and it posts similar gainsWhen would you recommend doing the first oil change on a new truck?
about 5mpg better than the other brands that are using a dpfThe dirtymax goes 10k between changes, gets around 10mpg, and gets regular conventional oil. Hooked.to a trailer the fuel.economy is so bad there is no point.
So the 6.7psd gets better fuel.economy than the 6.6 dmax?
Have you done a used oil analysis on the royal purple?
I don't think the RP has the same zinc content as the rotella T6, which may or may not have any impact on engine longevity.
I'm averaging about 15.2mpg on mine w/ T6 with a lead foot and city driving.
Ive been running Royal Purple since day one.
Before DPF-Delete... Oil was black within the first 1,000 miles.
After DPF-Delete...Oil gradually started staying cleaner and cleaner as I cycled oil changes.
Current OIL change has 9,000 miles on it and the oil is STILL "Crystal Clear".
On another note.
How many of you guys have had an oil related engine failure due to lack of lubricity. The "SCAM" of oils is an age old battle and obviously still is!!.
LOL__ MOST guys dont keep a truck long enough to even give a rats butt. OR they blow a rod out the side of the block long before the bearings ever consider a failure due to "bad oil"
As the Wallstreet Journal reports at the bottom of their columns.
Im long term for "Royal Purple"
what royal purple are you using ?
On the 250, if I can keep turbos in it for more than 5 K.... I would change the oil to something better, and change it more often...... LOL Last time I changed the oil was in Beaumont, TX, but I only changed out 2 gallons, out of the exhaust pipe, in the Waffle House parking lot... LOL
I find that the Ford stuff, changed every 5,000 is easier for me. I am also one of the guys that will most likely NOT keep his rig for 150,000 or more miles, so overall longevity is not up front in my mind. Also, every 5 k is just plain easier for me to keep track of... That is for the duallie... is is less than 2 months old, and I am about to change the oil, again, at 15 K next week... Honestly for as quickly as I put miles on, it is just easier for me to keep up with....
