Hi guys, this is my very first post. I tried use the search button but i didn't find an exact answer for my question and finding correct information regarding oil specifications, in Internet seems to be impossible. It seems to be in a jungle lol
I own a 2016 Ford Focus ST (First Gen 2.0L Ecoboost) and based on Ford (Europe) specification, my car require a 5W-30 oil with Ford WSS-M2C913-C or D specification.
As per Ford requirements, I always used an oil with that specification but, last year, i started hear about LSPI (Low-speed pre-ignition) and that oil producers developed a new specification that is specifically made to decrease that 'issue. As far as i understood, that specification is known as API SP6 or ILSAC GF-6A/B
Well, the thing is, i know that M2C913 specification DOESN'T meet it, and that will never meet it, so i started looking for a 'newer' ford specification and i found these:
Ford WSS-M2C929-A
Ford WSS-M2C946-B1
Ford WSS-M2C947-B1
Ford WSS-M2C962-A1
The problem is that 'based on information i found in internet' noone of these specfication replace the M2C913, and I really don't want to use a specification that doesn't meet my engine requirement, UNLESS someone post me a solid evidence that using a different specification will not cause problems. Beware that I know that putting a different spec will very likely not damage my engine, but if they made so many different specs, there must be a reason... I also know that in case of belt driven engines, it's better to respect the required specification to not cause excessive wear to the belt... which is not my case since it's a chain driven engine... but as I think that there should still be a reason to use the suggested specification.
So, to make it short, is there an oil specification that replace the M2C913 and that meet the API SP6 or ILSAC GF-6A/B specification? And also, is there a document somewhere that describe the differences and the requirements for EACH ford WSS specification??
Sorry for being too long and happy new year to everyone
edit:
I forgot to mention that in the past years I always used the following oils:
Liqui-Moly Special Tec F 5W-30
Fuchs TITAN Supersyn F 5W-30
I use to do track days with my car and both oils are waaaay better than Castrol (the one that Ford use), at least by looking at the oil temperature.
