Guy's, not to further confuse things. But my sercice manual clearly states 265 cc + 2.5 cc each leg. Not + or -.
I dont know how much difference between the oil will make if they are of same grade.
GHG - My astigmatism needs seeing eye dog. My optometrist keeps sending me remineders to visit them for eye exam. I looked again and you are right. It is 265+2.5 cc each leg. For our purposes ml is the same as cc - in terms of volume - and interchangeable.
There wouldn't be any gases released from motor oil, frothing is just churning it a making air bubbles in what's already there.I agree, go with real fork oil and use synthetic. It behaves better as the cold weather comes. Traditional oil makes a fork very stiff as it gets colder, synthetic less so.Scott
All of that is valid but I wouldn't expect any huge differences in gases coming out between engine and fork oil. And, a plunger with tiny holes being forced through oil is a great way to make froth and exactly what's inside our fork. You can create bubbles in a fluid without off gassing. Think ov cavitation on a boat propeller.The reason to go with synthetic is that it behaves more linealy across different environmental temperatures. With dino oil, it gets thick when cold and this makes the fork very stiff. The damping effect of the oil goes up exponentially as temperature goes down. This can make the fork so stiff it is unconfortable or even dangerous.Synthetic oil still gets thicker when cold but not nearly as much as dino oil. Dino oil behaves exponentially, synthetic behaves more closely to a linear increase.Scott
