BullDawg, looks great for your Titan, (and for Amsoil too).
Thanks for providing hard data!
r_mojo1, nope. Non severe oil change interval is 7,500 miles, but please dbl. check your "NISSAN Service and Maintenance Guide" to verify, (mines out in the Titan).
Owner's manual does state under Change intervals [p. 9-5]
"... Operation under the following conditions may
require more frequent oil and filter changes:
- repeated short distance driving at cold out-side temperatures
- driving in dusty conditions
I wouldn't do this interval, (7,500 mile), with dino though, and I also believe in first oil and filter change at 1200 miles, (the engine break-in's end point), or less, (to more dino).
Also, before switching to synthetics, you have to consider when you think is the best mileage to do this at, as there is lots of disagreement as what is correct, and even if it should be done at all. Do a search on synthetic, dino, dyno, Amsoil, Mobil, Red Line, Royal, oil, etc. as there are lot of threads here.
You will see people on here saying 2k, 5k, 10k, (miles), or whatever, and even the manufacturers disagreeing: everything from Mobil 1's no dino break-in; Amsoil's 500 mile dino recommendation; to Red Line's 2,000 mile dino to synth switch.
I would think it would depend on your driving habits too. Just make sure the oil meets spec. from owner's manual.
"RECOMMENDED SAE VISCOSITY [p. 9-5]
- SAE 5W-30 viscosity oil is preferred for all
temperatures.
- SAE 10W-30 or SAE 10W-40 viscosity oils may be used if the ambient temperature is above 0°F (-18°C)."
"ENGINE OIL AND OIL FILTER RECOMMENDATION [p. 9-4]
... Only those engine oils with the American Petro-
leum Institute (API) CERTIFICATION MARK on
the front of the container should be used. This
type of oil supersedes the existing API SG, SH, or
SJ and Energy Conserving II categories.
If you cannot find engine oil with the API CERTI-
FICATION MARK, use API grade SL Energy
Conserving oil. An oil with a single designation
SL, or in combination with other categories (for
example, SL/CF) may also be used if one with the
API CERTIFICATION MARK cannot be found. An
ILSAC grade GF-III oil can also be used.
NISSAN recommends mineral based oils. These
oils must, however, meet the API quality and SAE
viscosity ratings specified for your vehicle."
