I appreciate this reply! If you've got time and are willing, please tell me more about why the higher-grade oils are more suitable for cold climates. Is there no benefit at all to running the top tier stuff in Houston? I mean, my pockets will love that, but the hobby snob in me always wants a reason to go big haha!i chose the PCEO 5w-40 with the help of Dave. living in houston we don’t get the super cold weather so we don’t need the higher tier oils that they sell. the 5w-40 was chosen specifically for the insane HTHS number in the low 4’s. both my silverado and the woman’s honda accord will be running on it soon.
As far as HTHS, is there a point of diminishing returns, or such a thing as too high for a given climate, vehicle engine type, etc? Did you ever consider the premium 0w40 just to cover a wider base for out-of-state trips and whatnot? Reality is that my family (and most, I bet) isn't going anywhere if there's even a remote possibility of the weather dipping to where a 5w won't work haha. I'm more just asking. questions because I'm getting into this and interested in what others have uncovered. When searching, I especially began seeking out reviews and posts from folks in southern states, so I really value your opinion and experiences.
What would you run in a RAV4 Hybrid, given the 0w16/0w20 ("but be sure to go back to 0w16 next time Gadget!!") Toyota recommendation. I see that the manuals outside the states list acceptable oils as 0w16, 0w20, 5w30, 10w30, and 15w40. Pretty crazy to see, but definitely leads me to believe we could run the same oil in both vehicles without issue, which would make changes much easier when doing them at home. I just wonder if I'm missing something with the hybrid system meaning the engine gets less use. In the end, if Toyota specs up to 15w40 globally, I don't see why 5w30 or 5w40 should be any issue in her Rav.
