It's been my observation, and maybe I'm wrong, that in most engines you get the better fuel economy with say 0W-20 only up until the oil and engine come up to operating temperature. At operating temperature there isn't much fuel economy to be had versus 0W-40, unless we're talking about very light throttle application in a controlled testing environment. However, out there on the open road, while under load, pulling a trailer, the 0W-40 will undoubtedly provide better wear protection and more margin for fuel dilution than your garden variety 0W-20.
I watched the entire video, start to finish. The Hurricane inline six has Euro-Engineering vibes. Alan Falkowski made some generalized statements about how good thin oils have become, describing oil manufacturers almost like miracle workers. He also made the case that people should use the Start/Stop technology that comes with the Hurricane Engine. I don't like it when people, especially engineers, make generalized statements without backing those statements with data.
For anyone who doesn't want to spend time watching the entire video, I broke it down by topics with time stamps:
- Introduction to the interview with Alan Falkowski on the development of the Hurricane engine, its features, and its use in upcoming vehicles like the 2025 Ram 1500 and Dodge Charger. Alan shares insights on the transition from the Hemi engine to the Hurricane engine, emphasizing the importance of meeting modern performance and regulatory requirements. (Start of video)
