Interesting. How did you come accross the viscosity required? It doesn't mention in my service book or on the bottle. Which is why I double checked with the service centre.

The Euro definitely requires 75w80. Not sure why those Honda service centers (are they dealers?) said to use 75w90, especially if Honda doesn't sell a 75w90 MTF. I suspect that those service centers use whatever gearbox oil they have in the drum, which is usually 75w90 because that is cheap and common (used by many other car brands). That was the case for my dealer where they used magnatec instead of FEO, just because they could use magnatec in the other cars that they serviced there.

Honda MTF Plus (which is the original Honda MTF) and HondaMTF 06 (which is the equivalent to Honda/Acura MTF II) are 75w80. I have the service manual for the Euro and it says specifically to use MTF II. It even says not to use engine oil in the gearbox, which was actually recommended for older Hondas.

I also have an Acura bulletin announcing MTF II 75w80 (MTF 06) and saying it is for all Acuras/Hondas and that all new vehicles would come with it from the factory beginning 2007.

will MTF 06 be good for older cars as well?

For older Hondas, yes. It replaced MTF Plus and original MTF.

Nice.. I like when someone tries to disprove me, and can actually back themselves up,

Nice reply, and fair enough, I wasn't aware of your sarcasm, so I took it as a flame.

But, all well addressed.

In regards to viscocity of the GB oil,

75-80 and 75-90, both will do fine in the box.. especially for the earlier model Euro's like mine, i'd be pushing for the 75-90 in mine.

Haha, no problems.

Yeah, I was thinking that. However, I never really drive hard so using an oil of a heavier viscosity wouldn't be necessary/the best idea. I would probebly want to use something like Royal Purple/Amsoil/Neo in my trans if I was doing drags/track work. However for the street, I think OEM will suffice. Unless someone can find me a DAMN DEALER for Amsoil in Melbourne.

Have you ever used Neo Engine oil? I've spoken to two mechanics (one in particular) which say that they/customers have used they narrowed it down to the oil most likely causing head damage/seal damage. I don't see how an API approved oil would do this....

Why would an older gearbox require 75w90 over 75w80? Have you opened the gearbox to confirm that the tolerance has increased to require a thicker oil?

Ok,

Phased- never used neo engine oil to be honest, only gearbox.. Out of all the oils for engines, I'm a fan of FUCHS 10-40, it's made for jap performance engines, and high revving engines, and it's cheaper than most oils too, eg castrol edge..(which I like too)

Aaronng, if your box has copped a beating, or you have a lot of km's there is nothing wrong with jumping up a notch in oil, obviously if your car is relatively new, not driven hard, and has low k's, stick to oem specs..

Mine has 75 on the clock, but I drive cars relatively hard.. So as a precaution I'm planning on jumping up a notch.. But no one has to, the oem spec is fine, it's just my personal choice.

When I had my integra rebuilt after 1500kms I was using Fuchs GTO 10w30 Semi-Synthetic. I liked it. Then after 10,000kms switched to full synthetics. Had Motul 300V Full-Synthetic in there and dispised it. Changed it after 1200kms. Made the engine very chattery/lacked response down low. It was the same viscosity too. It's been Royal Purple ever since.

I wouldn't mind trying out neo, expessially for the summer as you can actually obtain the 10w30 in Australia unlike Royal Purple. However, I can't get past what mechanics have told me. So I really want to get Amsoil but I can't for the life of me find a retail outlet in melbourne.

Why don't you checkout www.rocketindustries.com.au

They usually have everything and anything, ask them to post it?

Ps. 10-30 would be awesome for winter time in a high boosted suby, I could only ever find 5-30

Yeah, I'm just picking on this because I have 82,000km and 5 trackdays on mine and 75w80 is still fine.

Having a track day or 2, won't really hurt the box that much, if you are shifting correctly, and not over-doing it..

But when start banging the gears with the clutch being flung up and aggressive, gears and gearboxes don't like that too much (trust me, I know the hard way LOL), and to keep the oil in the box working just that bit longer while you are smashing it, I'd go the thicker..

but if the car is still relatively new, and all is in good shape and looked after, the OEM is more than fine.

I'm just a little podantic, and prefer going that little bit thicker.. especially for the 1st - 2nd gear shift.. it's always the hardest one anyone will do..

sorry im still abit noob at this.. which one would be a thicker oil.. higher the number or lower? 75w80 or 75w90 etc..

and my cars done 58,xxx kms.. and my friend recommended the castrol one.. any experiences with the castrol transmission oil?
