Whenever I need oil I either go to Opie oils, which are usually well priced, or just have a good look on E Bay, often there are "multi buy" offers that further reduce the cost.

Sad to say they they beat the price of anything I can buy from any of the M/C shops around here so tend to buy on the net. Sign of the times.

Only exception is car oil, the local family run VW garage sells it from a "bulk" drum and for a very good price so they are always my go to supplier when the cars need an oil change.

Have been using Mobil Extra 2T in the Kawa's which is semi synth, I did try some Silkolene full synth which was recommended by someone, but it ran like a pig so back to the Mobil.

Most people say that you dont need full synth 2T oil in a road going bike. I am happy with the Semi Synth so no plans to change again.
