Pick my summer oil

[Camprunner]

Prob do my summer oil change in April I don't do the millage I use to although this OCI will be used for towing my 5,000 pound camper with my 2012 Nissan Pathfinder 4.0 VQ40DE V6 and it can be hard on oil esp towing in the heat hear is what I have on hand. Mobil 1 0w40, Penz yellow 10w40, Chevron Delo XLE simi syn 10w30. Prob run for 6,000 hard miles Nissan calls for 5w30 although when the motor first appeared in "05" 10w40 was an option and many run 40 weight oils in this motor without issue.... So what to run!?

An HDEO 5w40?

M1 0W40

Run the 10w40. check level frequently . Works for Briggs and Strattons too. Haz trans cooler? How is cooling system? etc.

Amsoil SS 10w30. Very stout, shear resistant, and will easily handle your interval.

And I'd wait until mid to late April as the winter isn't over up here. I do my summer oil changes in May.

From your choices, Delo 10w30 hands down. Tough oil, great heat and shear resistance.

That would be my first pick as well.
IMHO, many people using thicker PCMOs might be better served using HDEOs.

Cooling system is good I have 54k on truck had trans fluid flushed and replaced at 45k and has large trans cooler.

What ever wt your engine calls for should be used year round. Brand of oil is another thing.

 

[Red91]

Another vote for the Delo.

 

[toneydoc]

Mobil 1 0w40 will handle it fine

Look in the manual where it lists oil viscosity by expected outside temp. Use what they suggest. How hard is that? Hopefully none of your oil stash was bought at Dollar Tree or Family Dollar.
