I'm just about to change the oil as part of my 30k service and the only 20w50 oil I could find was this Morris Premium Multigrade 20w50. This is the same stuff I used on my 24k service. When I bought it then, the guy in the shop said it was semi-synth, however this time, they said it was mineral oil.
Is it going to do any long term damage to the engine using mineral at 30000 miles. It's the only 20w50 I can find round here.
It's an 1150gs by the way.
