[size=2px]Was the service done by Hunts? if so be very wary, the last bike I bought from them they completed a service, stamped the book, and gave the bike an MOT. [/size]
They didnt change the oil or filter, air filter, spark plug gaps were wrong and looked original, faulty spark plug cap wasnt attached properly, rear diff level wasnt correct and front pads were shot.
In addition the rear brake switch was broken and one of the two rear brake light bulbs was blown. First ride out I got pulled over by the police as I was unaware I had no rear brake light, was able to show him that the bike had passed its MOT the day before.
Hunts? wouldn't touch them with a barge pole, replace the first letter with another!
I do UOA on my bikes and cars. The lab says time on oil is nothing but a waste of money. You should never change oil on time, only miles.
You are paying for a additive package that prevents acidic conditions so oil sitting on your metal parts is not degrading your metal.
I will never change oil on time ever As long as the additive package is quality as with our oil it is, then only mileage will break it down.
My UOA come back great and all have said to extend miles between changes. The last time they told me to go to 6500 miles and the UOA came back fine.
I hate oil threads but if you have a UOA done there is no guessing just factual information on the elements and how much are in your oil.
As far as make up oil any one that meets the spec will be fine.
And remember the new amount is 3.6 liters. Most dealers just dump 4 and that puts you at the very top of the oil sight glass. You want mid circle of the center red ring for a correct level.
