Have to buy some GL5 75w-90 gear oil. After lots of searching the net I've found:
* Mixed reviews on Redline 75w-90ns (extremes too - some really love, some really hate).
* Consistantly good reviews on Castrol Syntrax (although nobody raves about it).
* Excellent reviews on Motul, but it sounds like it's a heavy duty race oil and can be hard to shift in colder temps (presume this isn't a problem for Auckland). Also sounds incredibly expensive.
* Almost no info on TRD gear oil.
Thoughts / recommendations / preference? I'm leaning towards syntrax.
Last gear oil topic from me... I swear.
