Why do "Chinesium" chainsaws need a richer oil mix?

I hope my above post is fairly clear and you can see the 4 engines of 35.2, 76.5, 91.6 and 121.6 cc.

That is, Holzfforma G111, G466, G660, G888.
Pretty low HP numbers(G660 lower Hp than a Ms400c) and notice the test figures include the use of a catalyst muffler.
None of these are EPA compliant.
 
If an OEM has the proper quality and documentation procedures, it doesn't matter where the product is made. A Stihl saw made in China would be just as good as one made in Germany if they set up all of the same procedures. We saw this when the Japanese car manufacturers started to manufacture here. There was no loss in quality. Meanwhile, after about 50 years in the US market, the big 3 American auto manufacturers are far from matching the quality of Honda, Toyota and Subaru. It's the system, not the country. I am not saying the Chinese clones are as good as the originals. I have no experience with them. My best guess is they are not. But I would be pretty sure a genuine Stihl saw made in China would be just as good as one made anywhere else.
Having spent a number of years working for both Japanese and American Tier 1 automotive suppliers, I'm going to disagree slightly. When the Japanese first started making vehicles here, their quality suffered because the workers didn't want to follow a bunch of rules made up by a bunch of "Japs". It took a while, but those issues got worked out. At the end of the day, a good production systems helps a good worker do an even better job, but it won't make a lazy, arrogant, idiot any better than the day he/she walked in the door.

That's right, as far as the catalyst muffler is concerned. On the other hand, presence in the database means compliance ( with the lowest possible "useful life"). And, of course, maximum power is given in kW, not HP.

They are not being sold with catalyst mufflers that I have seen.
If they are compliant they will have a compliance certificate number like these.

Not necessarily. The mark on the end of the sticker does mean that Stihl has documented that the saws are compliant when they leave the factory. I'm not sure if that ANSI spec requires the saws to actually have the mark or not. If the ANSI spec doesn't require the mark to be on the saw in order to be compliant, the the saw doesn't need it.

ANSI and the EPA are two different things. ANSI is voluntary and the EPA is backed up by the Clean Air Act.
If they are EPA compliant the will have a sticker stating such as the ones I posted pictures of do.

I worked for a Tier 1 to GM at one time and your comments are spot on.
Chinese manufacturing is OK with someone like Toyota, Honda, Stihl, etc over seeing the operation. On their own not so good.
In addition the methods they use to make raw materials are antiquated and thus they are lower in quality. For instance Chinese steel is still made from iron ore lump and fines, whereas US made steel has been using benefacted pellets for decades. As a result US blast furnaces have much tighter quality control over their end product.

Compliance with ANSI B175.1 is only apparently voluntary, as it is required by Title 29 (Labor), so it is unlikely that any recognized manufacturer can afford not to comply.

This is true of the sticker. It should be placed somewhere so that it is visible to the user.

That would be true if the saw is used commercially. If you're not, it doesnt matter. But something to be aware of for the tree service and loggers using knockoff saws.
 
Compliant machines are required to have a sticker stating as much. In addition they are required to have a certificate of compliance. These chicom knockoffs have neither of these.
The epa has a certificate of compliance data base that you can check btw.
My Stihl MS500i has no such sticker. And it is a genuine Stihl product, made in Germany.

A lot of data there. But I did not see a column stating explicitly "EPA compliant." The 50 hour service life is rather concerning, though. I would expect more than that from any pro saw.

Well, they have lazy, arrogant idiots in Japan also. But mistakes should not be allowed to leave the factory.
 
There never was one from the moment I got it new. Only the dealer would have had a chance to peel it off, and I don't know any reason why they would do that.
Every one I've played with at several dealers had had the certification table on it, it's also easily spotted on every picture you can bring up on Google images with the tank handle in the shot. The dealer should have noted it missing and replaced it. It's not a "can't be there, oh well" sticker. In the case of new sales

Well, I don't have an explanation for that.
