Opinions please, looking at Texas Refinery Corps Pro Spec 5W20 and 5W30 versus Lubrication Engineers Monelec Tetra Syn 5W20 and 5W30. Hot mixed driving conditions. 2016 Nissan VQ40 V-6 and 2005 Dodge 2.4 L I-4. Thanks

Texas Refinery is good oil but 5W-20 is totally unnecessary in hot weather.

Follow the specifications of your engines, unless Merk has started underwriting warranties, which I highly doubt, or if you simply don't see it as a concern.

The Dodge is spec'd for 5w20 whereas the Nissan calls for 5w30. Both oils meet the Sn requirement, but I'm torn on which to use. I have used TRC's exposed bearing grease in the past and it was absolutely great stuff for the application we had. Little in the way of UOA's on both that I can find, but both company's products seem to get good marks here. May just try one brand in each vehicle.

I wouldn't worry terribly much, as long as you've got the certification and viscosity you need, and UOAs on different vehicles have limited utility. Not overpaying is a good starting point. wink
