Oil Change Intervals

[sjl2725]

I haven't had the truck long enough to change the oil and without having the manual in front of me, I don't know the recommended interval. What does Ford say? Also, I have been Spartanized for 2 months now- should I shorten the interval between oil changes? If so, by how much? Truck is mainly a daily driver, and I don't hog on it very often. FYI.

Someone needs to come up with a maintenance schedule for tuned trucks!

With the DPF off you could probably go 10k miles between, with good quality oil.

With the DPF on, no more than 5K or sooner....depending on how much oil your truck makes.

[sjl2725]

what do you guys consider "good oil"? Rotella or what?

synthetic you can go 25,000 at a minimum. Oil filter and keep topping it off.

With The dpf/cat on you must watch the oil level. It will be increasing as fuel dilutes the engine oil during the regen process.With the dpf/cat off there is no fuel diluting the engine oil so your not forced to service at 3K-4K miles. Maybe more like 5k and much more if your using full synth. oil with the dpf deleted.

If your egr isn't deleted or blocked off the soot from it mixes with the oil too. I keep the milage to around 5k and full synthetic.

i've been running the motorcraft oil and changing it every 5k but my next oil change i'm gonna switch to rotella full synthetic and start changing at 7,500k miles after i deleted the dpf there was a very noticeable difference in how much oil i drained

I change mine every 5000 miles and use SHELL Rotella T 15W40

Change mine every 3,000 using regular chevron Dello. ive heard about gasket problems in 6.0 and 6.4 trucks using synthetics, synthetics are far superior lubricants but because of availability i choose just to change my dinosaur oil every 3,000

ive heard about gasket problems in 6.0 and 6.4 trucks using synthetics

what would cause gasket problems from using synthetic oil?
