I am using Mobil 1 10W-30 and a Napa Gold filter in a 2004 Nissan Frontier with a 3.3 V6. What do you experts think?
Is this a good combo?

I'm no expert, but that seems jussssssssst fine!
What will your OCI be?
Definately not an expert. It is a good combo, BUT, I would use the Mobil 1 5W-30. The reason being, the 5W-30 is actually a more robust oil(40C cSt=64.8----100C cSt=11.3) with a little better low temp flow and pumpability. Strange, but the 5W-30 is actually a more robust oil.
Frank - Good point!
My oci's are between 6-8,000 miles. I tow a boat with this thing. It is a crew cab longbed. It is 2wd but has the robust 4wd frame and lsd rear. Tows a 4500lb boat well. The manual says 5W-30. When I called the local Nissan dealer here he said they use 10W-30 dino. I have used M-1 10W-30 in my 1998 Chrysler and 2000 Nissan Maxima since they were new. Why do some of you guys recommend 5W-30? The pour point is -45F and -48F for 10W-30. I don't see much difference in the flow rates of these two. Cold start up flow would seem about the same to me. So, should I stick with 10W or switch to 5W. Also, what about their truck and suv formula? Any better than reg M-1? Thanks for your replies! I love this truck. The only thing I don't like about it the 3.5 qt oil pan.
I was thinking of switching to a 6000 mi oci. Anyone have any thoughts on what would be the better oil for this thing?
i'd really favor the 5w-30 w/6000 mile max oci with that small oil pan. mobil 1 is a fine product.

After it gets done betting sheared in an engine, its kinematic viscosity is often less than 10 cSt. M1 10W-30 doesn't use nearly as much VIIs and has a much more stable viscosity over time.

What does the increased density do?

I am not near to being an authority on motor oils. I have taken, as it were, a crash course on motor oils in the last two months.
I will try to explain why I recommend the Mobil 1 5W-30 over the Mobil 1 10W-30.
The first characters 0W, 5W, 10W define the cold flow/pumpability of the oil. a 0W is rated at 6200, -35C for cranking and 60,000 at -40C for pumping. 5W is 6600 crank at -30C and 60,000 pump at -35C. 10W is 7000 crank at -25C and 60,000 pump at -30C. You can see that a 0W will crank/pump better than a 5W, which will crank/pump better than a 10W. However, the 0W will require more viscosity index improvers than the 5W, which requires more than the 10W.(synthetics will require fewer VII than mineral oils of the same grade) Depending on many things, including OCI this may or may not be of concern for you.
On all three of the oils above 0W/5W/10W, the next number is 30. A 30 grade oil has a 100C cSt viscosity of 9.3 to 12.5, no matter what the W number may be. Mobil 1 10W-30 has a 100C cSt of 10, toward the bottom of a 30 grade oil. Mobil 1 5W-30 has a 100C cSt of 11.3, more toward the top of a 30 grade. I am going to use a custom blended 5W-30 in my truck that has a 100C cSt of 12.4, yet it is still a 5W-30. The Mobil 1 5W-30 is a more robust oil compared to their own, and other, 10W-30 oils.
Amsoil makes a 5W-30 HDD mixed fleet oil that is very robust. It has a 100c cSt of 11.4, VI of 174, HTHS of 3.5, 1375 ZDDP, and a TBN of 12.2. All 30 grade are not the same, there is a lot of range in the 30 grade specification yet still a 30 grade. For some reason, there are 5W-30's that are more robust than the 10W-30's. Buying a 10W-30 to get a little more robust oil may be just the opposite of what you wanted.

Are the numbers higher cause of the visc improvers?

Thanks guys! I appreciate all of the info. Unless someone can recommend a better viscosity I guess I'll switch to 5W-30. I'm still undecided as whether to use reg M-1 or their truck and suv formula. Thanks again for your help!
