Magnatec Professional is mainly a trade product from what I have read though some Ford dealers stock one for the new Focus and Fiesta Ecoboost engines, I think it is either a 0w20 or 5w20.
Edge is the top spec product in Europe.
Magnatec is the middle tier.
GTX is probably aimed more at older cars and those who just want to add the cheapest oil they can find.
Though I suspect GTX would be the perfect oil for the RX8, most specialist for the rotary lump seem to advise a 10w40 or 15w40 mineral oil, though some say you hydro cracked oils.
One thing I will say about Castrol products is I have used them for many years in my old mk3 diesel Mondeo that did starship miles, my current V50 and the BiL's Vectra with a 2.2 direct injected petrol engine.
Most Volvo and Ford dealers seem to use Castrol oils, apparently the Ford badged oils you can buy in Ford dealers are Castrol also.
You seem to have written everything you know that is related to the words "Castrol", "Magnatec", and "Edge".
Did you ever read the original question and consider whether you had a worthwhile answer to it, or could you not resist putting your hand up as you used to in class as a little boy and say "Miss, Miss, I know! Miss, I know. Miss!"
Sorry, what exactly are you talking about.
Do you have mental health issues?
If not, should really get a mature adult to have a look at the drivel you post.
But just so you know.
The clue would be in you wanted to know about Magnatec and Edge and if there are differences.
If you bother to look on the Castrol site, UK one as this is the European section, you will see that the data sheets for the two oils in C3 are identical.
If you can't see the significance considering you ask about differences then that is an issue for you not me.
Though the simple fact that Edge is more expensive than Magnatec on a like for like basis, other than when on special offer, should perhaps indicate that Edge is very likely a better product than Magnatec.
Now go ask an adult to explain things for you.
Very correct, but the situation is confusing because Castrol have now produced a turbo diesel C3 rated version of their normal Edge 5/40. I wonder how different that is to the C3 version of Magnetec 5/40, as I think they are both listed as HC synthetics. I will post a UOA of the Castrol TD 5/40 later this year, so if some good person could post one from using the C3 magnetec we might get some idea of the different additives.
I really don't understand why the engine oil companies can't post a VOA with their data sheets, although one reason might be that they do change the contents on occasions.
