Oil Change & Other Questions

I tried the Rotella T6 5w40 on my last oil change. Then I bought a case of the good Castrol race 4T 10w50.

I've used Mobil 1 as well.

The 5w40 Rotella made more valvetrain noise than any of the other's I have tried, even after a valve check. I haven't run it for longer than ~1500 miles, but I don't think I'll be using it in the bike again.

I'm surprised about the mileage of the 1st oil change. I've done mine at 70-100 miles. Not saying it's super critical but better to know sooner if you have excess metal circulating around in there and figure out why.

Mild weather areas like So. Calif 20/50 is a good choice that's easy to find. Some filters bypass (with too much throttle) on cold start with a pressure valve so best to warm up for 3 min or so.

I recently switched to Amsoil and the bike shifts a lot easier with it vs. Rotella.

+1 on Amsoil! My 610 shifts a lot better and the usual "change the oil when shifting gets harder" isn't as noticeable. When I change the oil it always looks and feels like I changed it too early!

Which Amsoil grade are you guys using?

10W-40 synthetic motorcycle oil

Both the 10w40 and the 20w50 are great.

Motul 10-60 is a great oil to run in the 610 too! Shifts like butter

Does anyone happen to have the sizes of the crush washers for the oil drain plugs for the 630? I want to order a few and don't have any to throw the calipers to unfortunately.

Very true, I came unstuck with the same thing and people didn't believe me on here, not naming any names but they know who they are and they even called my abilities in to question. Can you believe the cheek of it!?

The sight glass is not the best.

So it is just synthetic oil that needs to be certified for motorbike use then?

Is there a reason you're resurrecting every old thread you can find on here, SMJ and other places, flynn? And nobody really questioned your abilities, only your capabilities given your situation...

I just like resurrecting old threads because I wonder if the OPs will find them afterwards. Anyway I did have a legitimate question as to the synthetic oils being the only oils that can affect the clutch or not. Why make a new thread when you can use an old, perfectly good thread?

I only question his judgment and tact!

I write my experience here . I use for my motorcycle and car older and current oil Mobil 1 5W50 since 1988. 85,000 km with Aprilia Tuareg 350 wind 185,000 km with Pegaso 650 GA I had 0 problems with the clutch even if Mobil1 5W50 is a 100 % synthetic oil for cars Change always perfect My TE uses currently Mobil1 5W50 peak life I do not recommend different gradations

My judgement and tact? It's a question about oil grades FFS, how could it be untactful? It's not as if I have resurrected a thread asking if somebody died in the end is it!?

He was referring to the same thread that you tried to dredge up...

Yes, THIS thread IS about oil. Let's keep it that way.

Oh right my post #50, okay. That was me just being a little cheeky
