I was at Wally World browsing the motor oils. I was looking at what other 5W20 oils for the Escape. I'm using the Magnatec on my first change that I have on hand.

I noticed on the Castrol EDGE 5W20 it has the A1/B1 spec plus GF-5 and the other GM and Ford specs it meets.
The Magnatec does not list the A1/B1 nor does M1 5w20.

Is the A/B1 a 'better' more stout spec?

The ACEA ratings are the European ratings. Someone correct me if I'm wrong, but I thought the ACEA removed A1/B1 classifications last year? According to oilspecifications.org, it was removed and if that is the case, the new full synthetic Magnatec formulation wouldn't have had the need to get the A1/B1 classification.

I do have a somewhat similar question though:

My Elantra manual states to use an oil that is API SN/GF-5 and that is "A5/B5 or higher". I don't concern myself too much with it as I look mostly at API Specs/Dexos qualifications, but I wasn't exactly sure what it means by "or higher". Would A3/B3 and A3/B4 be considered higher or lower than A5/B5?

Dexos1 (Magnatec 5W20 meets this spec) is considered a tougher spec than SN/GF-5, here's how A1/B1 compares to Dexos1...

A1/B1 is a fuel economy oriented spec that has been superceded by A5/B5.
A3/B4 is a high performance spec which does not focus on fuel economy at all.

Got it. I'm still a noob on what all the oil designations are.
It almost sounds like the A3/A4 would be better for a direct injected turbo like the 1.6
WSS-M2C945-A is Fords spec for 5w20.

Using A3/B4 oil in an engine speccing A1/B1 , A5/B5 or A3/B3 is fine.
Now i don't think you're gonna find too many 5W-20s with a HTHS of over 3.5 ( required to meet A3/B4 )
To get a A3/B4 oil you'll need a 5W-30 at least.

None I looked at have that spec. Its still under power train warranty so I may need to keep it 5w20 for now.

That's a good idea, i'm not saying that a 5W-30 A3/B4 oil would necessarily be a better oil than what Ford recomends, but it won't do any harm either.

A1/B1 hasn't been superseded by A5/B5. It's a current ACEA category. Most ACEA oils are synthetic or synthetic-blend -- sort of like dexos1 and dexos2 as others pointed out.

A1/B1 is mid-SAPS, while A3/B4 and A5/B5 are high-SAPS. Many car manufactures are recommending low-SAPS (such as ACEA C1 and ACEA C4 and also ACEA C2 and ACEA C3 to some extent) for direct-injection engines, as high-SAPS oils have shown to lead to catastrophic intake-valve deposits in these engines. I don't think it's a good idea to use a high-SAPS (high-ash) oil in a direct-injection engine for that reason. It will probably void your power-train and emissions warranty as well. Stay with what is recommended.

ACEA defines all A/B oils are high SAPS, C2/C3/C5 as mid SAPS and C1 and C4 as low SAPS.
