Hi again Spud
"My personal preference is 15W/40 motor oil". Do you mind sharing what Brand name you get.
The following article you provided says NOT to use 10-40W
http://www.calsci.com/motorcycleinfo/Consumables.html
(10w-40 oils should not be used in a motorcycle that runs the engine oil through the transmission - Para 1)
Whereas CSC tutorial says to use 10-40W.
So is the RX3 not running the engine oil through the transmission.
Thanks for your help. As mentioned earlier, if i can just know the Brand and Type to pick up from the local walmart etc, it would make things easier for me.
