Bubbadozer Posted June 27, 2017 Share Posted June 27, 2017 I tried searching on this forum for some info, and could not find. Doesn't mean it's not here, but I just could not find it... With that said, Has anyone ever used and or is it of to use Rotella T6 synthetic extreme temperature Sw-40 oil in their R1100RS? Thanks in advance, Scott Link to comment
James in OK Posted June 27, 2017 Share Posted June 27, 2017 Rotella T6 doesn't meet the fairly antique oil spec for the R1100RS and other oilheads. Mobil 1 V-Twin does, and is available at most neighborhood auto parts stores and big box stores. Link to comment
Bubbadozer Posted June 27, 2017 Author Share Posted June 27, 2017 (edited) How about Castrol 20w-50 4T oil? Edited June 27, 2017 by Bubbadozer Link to comment

Thanks in advance, Scott 5W-40 oil doesn't meet spec for your bike, especially in Summertime temperatures. You should be running a 20W-50 or 15W-50 oil with an SG or SH rating. Link to comment
Jim Moore Posted June 27, 2017 Share Posted June 27, 2017 I LOVE Rotella T6, but I think it's a little thin for these bikes. I use good ol' Mobil 1 15-50. Link to comment
dirtrider Posted June 27, 2017 Share Posted June 27, 2017 How about Castrol 20w-50 4T oil? Morning Bubbadozer Yes, I use that a lot on the older BMW 1100/1150 bikes. It fully meets the BMW oil specifications for the older BMW boxers. Link to comment
