Out of curiosity, how are you handling the possible warranty issue using a non-approved viscosity? I’d love to switch my Honda products to 5w-30 but can’t get over the worry that receipts that show the wrong grade could cause trouble.
If you live in the USA that would not be a problem with the Magnuson-Moss Warranty Act. Most turbos call for 5-30 or 5-40. 5-20 is ONLY being usedto meet CAFE standards so you can get that .00005 extra mile per gallon and it has NOTHING to do with engine wear and longevity. My 2018 Hyundai Kona AWD 1.6 turbo calls for 5w-30. All Audi's call for 0w to 5w 40. There is some issue not going to far only because SOME cars are sensitive to thicker oil with their adjustable cam timing that in all cases retards timing so it is on the safe side. So really going to 5w 30 is a win win for this fuel absorbing oil system.
Iirc, the Magnuson-Moss Act says that you do not have to use a manufacturer’s branded product to maintain the warranty, but allows OEMs to specify fluids types. So, while Honda can’t mandate the use of Honda motor oil, they can specify the oil type and viscosity. If this were not true, an owner could use straight weight, non-detergent motor oil of any weight and not jeopardize their warranty.
In the case of Honda’s 1.5T Engine, afaik 0w-20is the viscosity spec world-wide, so it isn’t just a U.S. thing. Honda’s Customer Service team can be absolute jerks to deal with and, in the event of oil-related engine failure could absolutely deny a claim if your oil change documentation showed 5w-30 instead of 0w-20. Now maybe they wouldn’t and maybe they couldn’t prevail, but fighting such a decision would take months of time I’d rather not spend.
I have been told by Redline that local dealers have tried to deny warranty from use of their non API oil but never from the manufacture. Once they pushed the Magnusen-Moss Warranty Act to have the dealer prove it was the oil, the dealer had a hard time proving it was the oil and it stopped there. Never the manufacture.
I think it would not take much when backed by an oil engineer and common logic of training a jury simple oil principles. With a Honda 1.5 turbo's massive fuel dilution problems, that going to a 5w-30 would induce a failure or even going to a 0w-40 of a top level oil like Redline or Amsoil Signature Series that the ADDED boundary layer strength would ONLY be a PLUS PLUS. With the Amsoil Sig Series that has more AW Phosphorous and is the only reason it did not pass API. NOW if you have ATF or non detergent oil yes ...you have a warranty issue and I bet the manufacture would come after that. Using high end boutique engine oil is not an issue from my research. Using cheap non-API private labeled oil from "Chip's Food and Fuel" you do have an issue. There also have be car manufacture mechanics on different forums that say they never denied the motor because of motor oil other then if they see RED as it being ATF or if it smells like Hypoid gear oil. Some take a sample to save but it never gets sent out and they just replace the motor.
That's fine, it's your car, do what you feel is right. I will take the risk on what I feel is right. Especially me with my manufacture were on a Hyundai that has been rumored to have thin big end rods that need a thick boundary layer of oil to stop spinning a bearing on a crank-to-rod bearing hit or rub.

Yes, with enough time and resources you could probably get someone (arbitrator, jury...) to agree the issue was not with the oil’s viscosity. But again, it takes a lot time and money, so I’d rather not risk it. Terry Dyson, for one, will appear as an expert witness for an individual. But I suspect his time ain’t cheap.
OEM dealers are evaluated by warranty claims compared to the norm and if their experience is substantially worse than equivalent dealers there are consequences. So, it’s not too surprising some dealers used the lack of Redline API approval (or any other excuse) as a reason to deny claims. Did Redline tell you what happened to these claims? Did corporate over-rule or was the consumer stuck? Either way, it does show that not using the specified fluids has at least the potential to make your life more difficult. Ymmv.
