Good read on 0w20 from Honda

[Mau]

I saw this PDF posted on a Acura forum and it was a good read.
Also shows the testing involved in certification for HTO-06.

My '03 Civic Si [@ almost 200K miles] really guzzles the 0W-20 I've tried. I'm giving a couple more brands a shot then it's onto 0W-30's.

Thanks for posting

The slides advises that not all of the older vehicles will get a 0w20 rec and will stay with 5w20.

I thought that both oils would be similar say above 0C/32F but the 0W will be better at low temps.

Therefore as the older cars will not move is there a larger difference at temps above say 0C.

Just note that this document was published in April, 2009. Things change.

I wonder why it doesn't mention the S2000 or NSX at all. It says the S500 won't be retro'd though.

I like how the 1.5% improvement on gas mileage between 0W-20 and 5w30 is represented by a graphic showing nearly a 50% improvement, LOL! 1.5% for me is down in the noise; repeatability and environmental conditions make up alot of that 1.5%. It was interesting the bit on HTO-6 is for used oil moreso.

 

[matrass]

since the paper was written a few years ago, wonder if Honda has actually gone to suggesting 0w-20 yet. can anybody confirm ?

 

[gfh77665]

And yet not a single claim in that paper that the protection of 0-20 would be equivalent to 5-20 or higher. In fact, they say it's all about fuel economy in the red outlined box. I agree, 1.5% (maybe) is "something", but it's not much more than noise.

A graph, or chart, like that one really makes small things look like a big deal!

 

[Indydriver]

These small incremental fuel mileage increases are not for your benefit. But, when you make millions of cars per year and are held accountable for fleet CAFE regulations, every little bit helps. The fact is, all manufacturers are going to have to take some risk with reliability to meet the next level at 54.5 mpg.

Yes, they have. Most new Hondas since 2010 or 2011 come with 0W-20 as the factory fill AND as the recommended grade on the oil fill cap and in the owner's manual. My in-law's 2011 CR-V has 0W-20 on the oil fill cap.

Honda has also retroactively specified 0W-20 for many of their vehicles back through 2001, as that slideshow predicted. On Honda's chart, these older vehicles show 5W-20 as the recommended grade and show 0W-20 as "acceptable".

Previous BITOG thread with that chart.

People actually believe there is a wear difference 5W-20 and 0W-20???

 

[gfh77665]

If no wear difference between 5-20 and 0-20, where exactly would increased wear start?? 0-10? 0-5?

No such thing as a 0W-10 or 0W-5. Yet. We need to talk viscosity at temperature. You do know that a 5W-20 and 0W-20 are the same effective viscosity in use?

Depends on the engine really. Some may be fine with a 5 cSt@100°C oil!

 

[gfh77665]

At "some point", an oil CAN be too thin. Do you agree? I know of course 0-10 and 0-5 don't exist - yet, but where is that point where oils are "too thin"? I don't know exactly where it is at, but I know we are rapidly approaching it, in the name of CAFE.

That piece is very misleading.
It claims that EU specs 20w for 01-08. They should have used an asterisk, its true they did but only for hybrids. Ditto Toyota.
I grabbed the first one without hunting.

Man get your flame suit on! Your 100% correct but common sense doesn't fly around here some times when it comes to this stuff.
The fan boys get all worked up in a lather real easy.

I'm no fan boy for the thin crowd. And I am certainly no Caterham follower. I simply did not see the above poster as 100% correct when it was implied that somehow 0W-20 would lead to more wear than 5W-20, perhaps I misread the post.

Pablo i was replying to this. The 2 post before you were mine.
