For crying out loud, I've never seen so many dissenting pinions on any such mundane exercise as changing oil from a motor. I mean, sounds simple right?
Wrong.
I'm at 451 miles on my FZ6, and it's almost time to change the manufacturer's oil out.
A mechanic who has raced all kinds of bikes says to change oil and filter at 500 miles, and with regular oil, and then switch to synthetic at 1000 miles and change the filter again. He says use Yamaha filters and Yamalube 4 (either weight,).
A very good friend of mine for many years who is supremely anal and has been a mechanic for years also says he uses Rotella-T synthetic and purolator pre-1 filters, but also added that I should only use what's specified in the manual.
I'm leaning towards a full sunthetic in 20w50, per the book, with the purolator filters. The friend said they are $5-6.00 and are way better than Yamaha filters that cost twice that.
Some guys here say Rotella-T is ok, but the manual clearly and in bold lettering says not to use oils for diesel or with additives AT ALL.
Is SAE20w50 available in synthetic?
I don't want to use anything with additives that will make my clutch slip...
What are some great quality SAE synthetics?!?
What's a good oil to use for the first change?
