Why is this even a question/thread?

More people are interested in going "back" to the 5W30 oil that the J-series engines still use in the rest of the world...

-Charlie
5W30 exhibits less HP, T, MPG, & possibly less lifetime compared to a 0W20 in an engine specced for 0W20. No more protection, not even in a hot climate like mexico, AZ, or NM. Please recall your honda engine rises to 202 degrees F every time it warms up, it never gets any hotter than that. The honda manual is very clear: use honda M.O., or another co.'s premium grade M.O.

ps did a Perfect oil change yesterday, 4.25 quarts of Mobil 1 EP 0W-20 with Mobil 1 Filter. Using BITOG, this is the best combo at the moment, I believe. Plan to leave in for 10-15kmiles. Resisted the temptation to blend in a quart of 0W-16 !

pps: using a higher viscosity grade than manuf. spec results in faster oil degradation due to longer residence time on hot engine internal surfaces- more on this next time.
What about where different grades of oil are spec'd for different countries for the exact same engine?

Ever heard of CAFE?

I started using 5w-30....
I'm really enjoying it, much smoother and quieter.
Oil temps in the sump are exactly the same as 0w-20. The same.

202 is your coolant....not the piston rings, sleeves, camshafts, ect....those temps are MUCH hotter than that.

Please go read HTHS....this is also a HUGE factor that CAFE flat out ignores.

Your blanket statement is incorrect. You can't prove any of those claims especially with the variance of driving styles, conditions, weather, and fuel quality.

There are other places to get info other than Bob.

Take a look at the flash point of any 0w-20 syn to a 5w-30 syn.......you will notice one is almost Always higher. Giving that oil an advantage in very high heat situations.

Of course any manufacturer who has their labeled oil is going to "recommend" using it. The nice thing about Honda is that it just says to use Honda oil, which is a P66 oil, or any synthetic oil with the latest API starburst on it. No Dexos, no MB, no VW, no Ford.....just latest API starburst.
 
wow, muh climate change.

meanwhile most in Europe have no clue about these American brands and swear by total and shell oils.

Murican marketing!
They also don’t really have to worry about things like CAFE either so they can run w40 and w50 oils all day long. :’(
