Hello everyone, I hope I’m not stoned the same way… It’s about the mannol 10w60. I stumbled over it on eBay and wonder that it meets the same standards as Castrol but only costs half (Api / Acea) . Where is there (founded) the catch? This is purely of personal interest I already have my oil It would be great if no answers would come in the direction like “just take xyz and don’t ask so stupid – because it’s just so…” Sorry also for d en oil thread but I found nothing useful in the search
