Any use rock oil 20/50 in their r1150gs?

No no a thousand times no Not another fecking oil question RTFM
You can use fecking rice bran oil if it meets the spec :rolleyes:
 
Yep, 120000 miles 2002 1150gs and I use rock oil 20/50 but not that one.

Rock Oil Guardian or the Gamma at about half the price.

Happy to be told I am using the wrong stuff , but it's quiter, cooler and uses less on hot long runs than 10/40, not that it uses much.

Always lots of talk about oil on here, quoting this and that, I am happy to try different stuff until I find what works for me

Hope this rambling on is of help

😱
 
My 2003 handbook says SF/SG/SH, just checked cos I picked up some Gulf 20W50 from the local farm supply place to save a special trip to pick up the usual GTX.

OMG!!! You use GTX ???

Oooops sorry, that was Duckhams :D
 
Finding 20-50w around here is feckin impossible, seems like it's all 5-30, 10-40 or super new spec stuff for long life diesels.

I'm considering speaking to the local chip shop!

Should b easy with Fuch being in town, but no :blast
 
Well go on then, pour that GTX (API SM) into yer boxer engine :augie

We stock 20w-50 semi synth Silkolene Super 4 amongst others up here in Shetland... I make sure we accommodate all the bikers inc tractor BM's as well as the usual cars selection...:)

Yes, but that's a turbo Subie, where the knock sensor doesn't work above 5k rpm and it's a race between that and the big ends if you run enough boost to detonate at redline. Anyway, if my bike survives the weekend ride I'll be draining out the GTX and putting in the lovely Such made Gulf 20W50 that's only SF.
