I've stayed away from Castrol oils. I heard/read that they don't have a true Ester base and that they aren't true synthetics - not when compared with the real synthetic oils. However, I'm happy to learn otherwise.
I've been using Motul 7100 4T (full Ester synthetic) in my bike for the last five years and really trust it. This past winter (April to September-ish) I used Motul 5100 4T and when I replaced it (done less than 5,000 km) with more 5100, about two weeks ago, I discovered that it did not wear nearly as well as the 7100 4T. So today, after only a couple of hundred kilometres, I took the opportunity to dump it while I installed my new Suter Slipper Clutch. I replaced it with 7100 and won't be going back to 5100.
