+1 I wonder if there is really much difference between the 10w40 and the 10w50. Advance Auto carries the Castrol Power in 10w40 and 20w50 for $9.69/qt but not 10w50 which the dealer gets $14.50/qt. Who knows. But I'll probably change my own oil next time I just like to have the dealer do the first service for warranty documentation. I think that all of the MC rated synthetic oils are about the same really. So, I shop for price.As was said earlier, talking about oil is like talking about religion - everyone has their own opinion and "sources" to support it.
That being said, glad to hear the Castrol is working good for you too; I'm having the same experience - no complaints using dealer installed Castrol.
I use Amsoil in my diesel truck and tractor and have no complaints there either.
I just can't imagine why a motorcycle company would risk their reputation and financial success by recommending a clearly inferior product. Yep, I understand sponsorships and "money changing hands", but that can't possible compare to the profit from increasing market share and selling more bikes without unnecessary claims.
I think it just reinforces the fact that most high quality oils with the same technical specs are comparable with little difference in performance IF changed regularly. Therefore there is room for different manufacturers to associate themselves with different brands for "marketing" reasons since performance doesn't really vary that much.
Just an opinion of course - isn't all of this?!
Walmart carries the Mobil1 4T 10w40 for about $9-10 which is the same price as the Castrol Power 4T at Advance Auto...so obviously they watch each others price point. I'll change at 3-4,000 or once every fall before layup.I agree and will do the same at my next (6000 mile) change. I've already checked, and my favorite oil change pan fits fine under the bike when it's on the the side stand. I probably won't wait till 6000 though - probably change around 4000.
I bought an extra quart of 10w50 from my dealer for $13.69 and haven't checked other sources yet. I was going to check and see if Wallyworld carries it. I do want to pick up some new washers though - I've had leakers before reusing them.
Thanks for the tip - plus Dazco says it'll make me go faster - need all the help I can get with my puny little 1600...Walmart carries the Mobil1 4T 10w40 for about $9-10 which is the same price as the Castrol Power 4T at Advance Auto...so obviously they watch each others price point.

Castrol has updated their formula since the most recent white paper oil test that amsoil put out. I read somewhere that Castrol used many bikes to develop their new oil formula (Power RS racing) including a triumph (not sure model). In the white paper castrol power rs r4 was tested (2009 test). At the dealer that I worked at I had a customer that wanted Castrol but could not get it for him due to the castrol formula switch over. I will note that when we disassebled his GSXR 1000 his clutch was is great shape with castrol oil as his choice oil.Where do you get the bad reports on Castrol? I've used it for years in everything with excellent results. I do use Mobil Racing 4T in the TBird and it has done a great job, but I see Triumph is now recommending Castrol instead. I can't imagine they would do that without serious testing and a good reason to do so.
