semi

Just wanted to check this. I'm switching oil tank for a replacement one and new oil filter. Been topping up with the remnants of oil from the last service, castrolGPS fully synthetic oil, but I've gone and bought motul 5000 which is semi synthetic this time. I know u can't mix them, but...

I use Shell fully synth Oils in my race bikes.. Ok to use 10W40 semi in an RSV? Thanks in advance..

what would you guys reccommend as a good oil to use for an 04 rsv factory:dunno? gona do an oil and filter change whilst shes tucked up in the garage for winter. cheers in advance:thumbup
