An oil that meets GM 4718M is hard to find except Mobil 1 5W-30 here.Mobil 1 5w-30 is very expensive here(450 yuan,1US$=7.6 yuan).Can I use an oil that meets MB229.3 or A3/B3 substitute it?Thank you.

Wow! That's over US$59/quart! I can't help think that it would be cheaper if you ordered it from the US/Australia/Japan and have it shipped to you. I don't know what your import duties and fees are. But even with the import duties and fees plus shipping it might be a lot less to ship a few cases direct to you. Maybe this is a silly question but has Walmart opened in China yet? If they have check them out. If you don't have a Walmart near you maybe they can ship to you.

Q St and Valvoline do NOT meet the GM 4718M spec - at least according to GM's approval list.
 
Nearly every additives company such like Lubzoil have a factory in China so China have some good products such like Sinopec.Chang'e-1 lunar satellite use Sinopec oil.Sinopec have oil meets MB229.3 or VW502 but have not oil meets 4718M.
Some people over there think No good oil in China ,this is not right.Most oil companies such as Mobil,Shell,Elf,Castrol,BP use chinese base oil in their products here.
My question is :Can MB229.3 OR VW502 substitute 4718M?

From Valvoline's SynPower page:

Exceeds all car and light truck manufacturer’s warranty requirements for the protection of gasoline, diesel and turbocharged engines where an API SM, SL, or CF oil is recommended. Exceeds European ACEA A1/B1, ACEA A3/B3/B4/C3 and all requirements of ILSAC GF-3 and GF-4 for API Gasoline Engine Oils and meets Energy Conserving Standards. Meets or exceeds the engine performance requirements for BMW, Bentley, Corvette (GM4718M), Jaguar, Lexus, Mercedes-Benz, Porsche, Rolls Royce, Volkswagen, Volvo and other high performance vehicles.

If you go to their spec sheet, note that they don't list GM4718M.

"Meets or exceeds the engine performance requirements" is oil companies mealy mouth way of saying "We recommend it for that use but the car manufacturer hasn't approved it"

You need to read these things like the oil companies were trying to mislead you without outright lying.


There spec sheet is interesting because it's one of very few US oils that is actually qualified for VW 505.01.
 
Caiwu, any good synthetic of the right viscosity will be OK in your engine. My only concern would be that you would be giving GM an excuse to deny engine warranty coverage if there was a problem that appeared to be oil related.

Read the GM approval list (don't have the link off hand, but it is posted here multiple times) - no Q St, no Valvoline. This is exactly why there are approvals - to cut through who has integrity and who doesn't in their performance claims.

No it's not. It's to make money for the auto companies. Especially in the specialty fluid area.
 
OEM approvals are a good thing, but don't necessarily mean other non approved products won't work well or meet/exceed that spec. I used to think less of OEM approvals, however, going back to the new Acura HTO-06 spec, I think they are of some value. I bring this up because this spec was created by Honda for Turbos. All the others either failed or were average at best at preventing deposits. I would not use an oil that didn't clearly meet that spec. The GM4718M is a pretty tough test and I would want an oil that clearly meets that spec.

Buster gives a great example. The HTO-06 is only secondarily about performance. If the car companies are so altruistic, where is this spec? Why not give it out for free? Then allow the oil companies to build to it, test to it and Honda certify to it, no charge? I'm all for test specifications. They should be open source!
