If Honda's data shows 5W20 is best then they would specify this or at least 0W30 in UK. Engine requires this oil or better wear appears a nonsense so pure CAFE!!


Oil recommendations by the manufacturer are going to be market-specific. That's not to say two markets won't have the same lube recommendation in the manual, but where there is a reason, they will vary.

It's not limited to motor oil, either.

On one trip to MN during the 90's from Canada ... only a few hundred miles south of my local market ... the factory fill rear diff lube was simply not available ... in stores or at the dealer ... in the same viscosity.

Not a domestic vehicle either; Toyota made in Japan model.
