Answer: No. The newer 0W-16 oils can only be used in 2018+ Honda Fit CRVs, and Accord Hybrids. Honda has not back-specced Honda Odysseys for the newer oil. 0W-20 may be used in the newer design Honda cars above where 0W-16 is not available, however. Yes, using a "thinner oil" results in marginal HP and MPG improvement, but in this case, it's not worth the risk to your engine.
