Been looking around and with Gen 2 including tests to combat lspi and help with small Turbo engines and Ford B1 spec adding similar tests, are they basically the same spec or is Ford B1 testing different? Some oils are meeting the gen 2 spec currently but not meeting B1. Is it just because they never got the license yet or Ford more strict???
 
Yes, those updated manufacturer specifications and API SN Plus basically address the same thing with regards to Low Speed Pre Ignition (LSPI).
 
Some ATF says "Dexron VI", but is not labeled for "Mercon LV". Both are low viscosity. It would probably work. But not approved by Ford.

You can have SN + that isn't B1 approved too though. Ex Penzoil Ultra Platinum

No, Pennzoil Ultra Platinum 5w-30 is -B1. Zoom in on the back of the jug at https://www.amazon.com/Pennzoil-550045201-Ultra-Platinum-Synthetic/dp/B01M266FWZ to see.

Those "WSS" Ford specs have always stood for "wussy" in my view.
GM's dexos1 Gen2 is the tough one, use that instead. Many more tests in dexos1 than the Ford wussy ones!
It is true that the -B1 Ford spec here does run the SN+ LSPI test on an Ecoboost engine specifically, while dexos1 Gen2 uses a GM turbo-DI in theirs, so there is small difference, not to worry about it, IMHO. Basically if you see an oil that has calcium below about 1500 ppm, you're not likely to get LSPI, or the flu from it either.....

More proof that the Ford -B1 spec is wimpy: Oils with mostly GroupII base oils qualify, where they aren't good enough for dexos1 (example, Mobil Super 5000, Valvoline Daily Protection (not a sunscreen, as I found out......)

This could not be the case some blenders just refuse to pay GM it's "fee" to license DEXOS. At one time GM wanted profits from each quart of motor oil sold for a DEXOS license.
 
As it was explained to me B1 was implemented to address Timming chain wear issues. Ford PCMO on most , uses a semi synthetic blend only API SN .

According to who. If GM spec is toughest one to meet don't you think Ford or any major automaker would say in manual ok to use GM Dexos spec for warranty. No the only reason everyone thinks so is licences are paid so oil companies put Dexos on front. Advertising at it's best. How many GM products are using oil.
 
According to all the gurus that post here - that even have provided us with links. GM is toughest.

No. -B1 just has the SN+ LSPI test, thats all, as timing chain wear is still a year or two away when the upcoming GF-6 happens.
The WSS Ford spec family has never been much to write home about.

No, Ford avoids the GM dexos1 and dexos2 specs due to proprietary intellectual property legal issues and corporate rivalry. Ford should unify on GM's better dexos specs, but won't for obvious reasons.

So what you are saying is an oil that is GM Ford, Chrysler specs as well as any other spec is just GM spec? No it is an universal oil intended to be used in multiple vehicles. If GM spec oil is so good why not get AC Delco oil as this is true Dexos with not having to meet other manufacturers spec.

Because you can get other oil that is just as good and cheaper.

Maybe the famous Lubrizol spider chart will help you understand how weak specs can be swallowed up by better tougher specs. Then you'll understand how the weak Ford and Chrysler material standards are actually subsets of dexos1.

https://online.lubrizol.com/relperftool/pc.html and put in API - SN Plus and then select GM Opel dexos1 and see it swallow the other specs.
 
Again a matter of oils on sale have to meet several specs not just GM spec. If you like GM spec because it is the holy grail of oil spec just buy oil with only Dexos spec. Aftermarket oils are multiple purpose oil not just GM. Aftermarket oils are approved and won't damage a vehicle it was approved for by the manufacturer. Simple. Don't use approved oil then you take a chance of the customer eating engine cost.

Just API because in other parts of the World Motorcraft is not a Semi Synthetic.

And Ford has shown simple spec meeting motor oil protects keeping the engine like new after torturing a 3.5 Ecoboost in manners most owners can not recreate.

That license is a scam.
