which gearbox oil should i use?

[Phased]

Guys there is an oil out there I used with my straight cut gearbox.. Called NEO,

fuc@ing excellent stuff.. 120 for 4 litres..

I have heard mixed opinions on the "Neo Synthetics" product line. Some mechanics are very much against Neo (Engine oil in particular) as they have "narrowed it down" to causing some serious engine problems, in some of their skylines/wrx's. Having said that... I know a couple of people that use it with no problems...

So much better than motul and royal purple, ps redline shockproof is ok too

Firstly, How exactly is it "so much better" than motul/royal purple? Are you an e-mechanic that reads posts of people saying "OMG xxx oil is the best, because the company targets the high end market and they say its the best"?

Do you have any proof of this? Have you actually compared all the oils? If you have you must have fairly deep pockets and change much more often than recommended drain intervals...

I'm not saying that it necessarily isn't better, or you havn't tried it. However, a post like the one above isn't very helpful to the original poster when all you write is an inane opinion.

To be honest, If I was willing to spend the extra/go to the extra effort to purchase it. I would be using Amsoil. No questions. However, I enjoy my discount/5 minute drive to get Royal Purple
