I hate to start an oil thread, but are the engine oil levels the same whether you use synthetic or dino?
I have an '04 R1100S that I've always used dino in and have always had to add oil every couple of hundred miles to keep the oil level in the sight glass at half way. I'd heard at 10K miles this should stop, but I have 16K miles on it now and I still have to add oil regularly.
At my last service I mentioned this and it was suggested I try synthetic, so I did. After I got the bike back from the dealer and rode home, I noticed that the oil level is now above the sight glass. When I start the engine, the level quicly drops below the sight glass.
Is there any reason why more synthetic oil is being used compared to dino? My owners manual says never exceed the max level on the sight glass. What says ye?
