Just purchased a Honda Pilot with 36k miles. Does Honda have my best interest (from an engine longevity standpoint) at heart in recommending 0W-20 weight oil or is this a gas mileage play? I have an Infinity Q-50 as well and there is a range of recommendations for the 3.0l from 0W-20 to 10W-30 (or maybe even 40) depending on climate conditions. There is a lot of debate on the Q forum about whether there is a trade off with the thinner viscosity oils in protection vs just providing less resistance for mileage or performance.
Anyway, I would prefer to maximize engine protection and longevity over marginal fuel economy improvements. The car had last been changed at a Jiffy-Lube type place so I immediately changed it to a 5W-20, figuring that was safe at the start of spring/summer in the mid-west. My instincts say 5W-30 would be better long term for the motor but I am not an expert on the topic.
What is the consensus thoughts here on the BITOG forum?
So my in-laws are running 5W20 in previous Pilot in Las Vegas. I do not have to tell you how summers are over there. Your internal engine temperature is maintained by thermostat, so regardless of ambient temperature oil will have very similar temperature in 0 degrees and 100 degrees. Difference is how fast it will reach operating temperature. I am not sure of internal engineering of current V6 in Pilot. Toyota for example can swallow anything. For what is worth, Mobil1 Australia recommends 5W30 in 3.5 V6. So 5W30 will do well if that is your preference. I run in my Sienna 5W30 although it is recommended for 0W20. But then, 2GR-FE in Toyota can run on 20W50 too.

For whatever a single data point is worth, my father's wife has a 2013 Pilot that she purchased new. It has had 0w20 since new changed between 5-15% OLM with mostly M1 AFE 0w20. It now has 177,000 mikes on it and has been relatively trouble free. Only issue was a stuck spool valve (I suspect) replaced by the dealer under extended warranty at 115k, dealership installed TSB update parts of valve, pressure regulator spring, VCM screen. It does not have VCM disabled and uses no measurable oil between changes. Seems like hers has held up just fine on 0w20.
Also, banner day, my 2000th post. Woo hoo!

Agreed, a 30 is fine. VCM hasn't proven to be problematic on these, that was more of an older gen issue with consumption. For me, running is 30 is most beneficial being DI knowing there is some level of fuel dilution, although not anywhere near some other engines.
I don't think you'll see a noticeable change in economy with 0w-20 over 5w-30. I had a 2008 CR-V and I ran 5w-20 until it was out of warranty, keeping a log of fuel purchases. Went to 5w-30 and kept a log for a year, and the average was slightly better (about 0.5 MPG) with 5w-30, but there were so much variation from one tank to the next that it was impossible to say the oil had any measurable effect. I've been running 0w-20 in my Pilot and I've got no noticeable consumption.
