because sometimes people find things that work better than what is suggested in the manual.

That sg/sf is a MIMINUM requirement....and the 10W40 is a general recommendation that covers most riding conditions.

Sometimes people crow about things that "work better" when they really don't have a clue.
You need to filter the advice you get carefully.

1st- this post should be in general. no T-shooting in this thread.

2nd- second question you might ask about the type of gas so go with the cheapest one it is ok with this bike, people and mechanics do recommend to use the high grade once in a while to get the throat (carburetor) or (carb) clear. Use gas additive same as we use in cars or (chem 12) for the same purpose.

3rd- personally i think over doing has no additional benefit so do not worry about going cheap. full synthetic or high octane won't make GZ a sprinter and you won't get 82mpg if yours cant achieve it.

4th- this place is full of wealth. people from all walks of life and places are here.

One of the first things I did when I got my bike was change the oil and filter. Got Suzuki motorcycle oil cause Im not taking any chances. It was $6 something a quart for it and synthetic was $12 a quart. One thing Id recommend, is checking the 2 orings while they are still in the plastic. I took the plug out and let it drain while i changed the filter and when i opened the new cover oring bag i noticed some idiot had stapled the 2 oring bags together and the staple went THROUGH the large oring.

That is when you say HO-HUM and use the old O-ring.

I have had my G.Z. three years,30000 kms.I change my oil every 5000 kms,never once have I changed the o-rings.I have never had a leak.The same for the o-rings on the valve inspection covers.So changing o-rings every 2ND oil change should not be a problem.I make sure to put a little clean oil on o-ring when assembling.

Not making any comment on this statement, just saying that the bike shop that always does my oil change (labour is so cheap that he does the full service, including oil & filter for the equivalent of around $30) uses 10/40.

edit:- $30 is the labour. With parts it's $60.

Of course they use 10/40 when the bike shop changes it, that is what is called for on the bike, a good shop won't deviate from that unless you ask them to, and some of them still won't.

I didn't say I was recommending it, just that it would be all right IF someone wanted to do that.
