Favourite oil?

[Mongrel]

Funny, enough I didn't see a topic like this come up in the forum search. Maybe that discussion took place years ago? Or maybe it's too dependent on whatever is sold locally?

Anyway, I've just been using plain Castrol GTX 20W50 Motorbike oil. I don't put on heavy miles or a heavy load and change it every year come winter storage time, so that's been more than adequate for me.

Apparently the local stores are getting some Shell Rotella T6 in on sale. Worth picking up? Bad idea? (My understand was that diesel oil was recommended)

EDIT: Hmmm, looks like the Rotella doesn't come in 20W50 anyway. Still interested in hearing what oil folks are running.

You can use what ever brand oil you want, however,,,,, I would NOT recommend using 'motorbike' identified oil as it has special lubricants in it for wet clutch bikes. :nono
You can use standard oil like you would put in your car/truck

i only use organic or non-gmo oil and i have never had an engine problem...

When my bike was new it liked BMW branded oil or Spectro synthetics, now it's old and doesn't really give a crap what I put in it.  Wallyworld Pennzoil 10-40 seems to work ok.

Oh my, an oil thread.

Actually, as it turns out, Castrol GTX 20W50 doesn't say motorbike anywhere on the bottle at all. I think it used to years ago (which is why I'm used to calling it that), but not for a long time. It's just plain 20W50 now.

I use Mobil 1 15W50 synth.  Have been for years and no problems.  Change it every winter.  If you put a web notification against the product number on the Canadian Tire's web site, you get notification of upcoming sales and therefore can pick up bottles of it for a good price like I did.  I stashed enough for three years (the recommended shelf life).

I wound up with Castrol 20W50. Not hard to find, and not crazy spendy. I had a fleet of RE5s (4) It was recomended then. If some crazy ol' rotary bikes from the mid 70's could be kept alive on the stuff...so can a hard workin' K1100.

Virgin Olive Oil ... really it is just the virgin part that gets me.  :yes

[racinrich]

I like extra virgin. for the bike rotella 15w40

I diggs the synth, alright. Mobil1 15-50. Went 10k since early June and it looks like it just came out of the jug. Will be changing it before spring tho.

Spectro Golden 4 which is a blend. Rotella once in a while to clean things up.

I don't have any favorite oil but at the service they seems to use Castrol Power 1 on my bikes and it's supposed to be good stuff.
