How did you go with that gearbox oil??? Update please..Well anyway, if you check the Castrol site, they recommend a different oil for the gearbox which I am going to use!
CASTROL VMX 80 75w/80 GL4
And for the diff oil it is different to what people here are recommending for castrol:
CASTROL MULTITRAX 75/90 GL5
Since this thread was created i have decided to use the following oils:
Engine Oil : Royal Purple 10w - 40
Fantastic oil with instant benefits (in feel). The engine runs alot smoother on idle and revving it is alot freer. Definitely recommended.
i'm about to do a service shortly and I live in perth WA. I never heard of the royal purple oil. Where can i get some?
I have some castrol 5-30W at home that is fully synthetic. Has anyone used this oil? or would recommend against it?
Whats the normal interval for gearbox and diff oil change? My car was 11,000kms on it.
This may be an old wives tail as it hasn't happened to me (my engine is still pretty new at 38,000km)...http://www.castroledge.com.au/product/product_5w30.php
this is the site of the oil i got it from, i looked in the manual at my local oil shop and it said this was recommended oil for my car. Ill give royal purple a go and let my brother use that castrol for his car as it seems to work for him.
Here is a clutch fluid story. My roadster has done 60k and the previous owner had the clutch fluid changed at the 40k service.
On the first real hot day of summer i go do some shopping, driving home the clutch pedal goes real spongy, it changed gears, but engagement was only cm's of the floor. Then by the time I got home its OK. Long story short turns out its some kind of heat soak and the fluid was boiling. The clutch line passes very close the exhaust system. The fix was Motul RBF600, it has a higher boiling point. Now even through the heat wave days no probs.
Thought this might be good addition to the thread.
