I used to get some fully synthetic stuff called Amsoil MCF from Opei, supposed to be the best. The old girl went through a litre roughly every 1000 miles. Bike had done approx 10K so switched back to Yamalube semi, doesn't use anything now.
Peter Brett in that article from Castrol oils;QuotePeter Brett says that they’ve discovered synthetic oils actually interfere with running in, for reasons which go beyond their low friction properties - there also seems to be a chemical process happening which hinders it. “Although you can treat an engine as fully run in after 500 miles, surface stabilisation continues for at least the first 5,000 miles of an engine’s life,” he says. “Synthetic oils actively prevent this from happening, and not simply by holding friction surfaces apart, although we still don’t know exactly why and how this happens. But there’s no doubt they inhibit the process itself. So the consequence of using a synthetic too early is your engine will never run in properly. I would even suggest waiting until 10,000 miles (16,000km) before using it in most engines subjected to normal use. Until then, you’re best to use an inexpensive but branded mineral oil.”
From the infamous oil thread
talk to dek about how to bed an engine in ..... manufacturers detail a break in procedure which everyone can follow, but there are several theories about how best to do it.My GS for example has almost no break in procedure, advice was just to avoid prolonged full throttle use ...ie thrash it , but not too much ! my local bmw service manager believes the harder you ride it in the first 600 miles, the better. Fully synthetic goes in at 600 miles.Hence why for first 600 ( mineral oil) it dont want to be mollycoddled) ...
