the reason it is graunchy is because u have most probably ever so slightly damaged your syncros. good fluid always helps and in most cases will sort the problem as discussed above
How often to change your fluid> well how long is a piece of string. It all depends on how hard you drive it... For example I know people who change there gear box and or diff fluid after every second race event... The harder its pushed, flat shifted, miss timed gear changed, raced etc etc the harder the fluid has to work and hence the more often you should change it. Ill expand on this.
With your gear box oil and the same with your engine oil... it is good to have a km limit, but the oil (and filter) should always be changed in accordence to how the engine is working. You might ask why should i change the oil at less the recommended km's? Well first you need to ask - what does the engine oil do.. clearly it lubricates but it also picks up deposits, micro particles and other nastie little goodies, at varying engine speeds temperatures etc - so there is a relationship between how hard your engine works and how hard your oil works to keep everything clean lubricated doing what its suppose to.
Now if u all enjoy driving your chosen honda as much as I do, you must surely put your car through its paces at different times and hence there are times where the fluid might need to be changed more frequently then others.
Some other things to think about - why does my gear box not have an oil filter?? - well no engine combustion so less of a need for a fliter as there are less deposits etc but what about that time i missed a gear - thats metal on metal people so there is now micro particals of metal through my gear oil (or worse) that cant be good for the bearings now can it...
Change your oil filter every time u change your oil
Turbo'd cars work harder so need a more frequent oil change...
Your car will last really only as well as u look after it - its not so much of a problem for standard cars.. but if you build one you put alot of money into it putting the best bits into it... so why not look after it wiht the best fluids.
Just to give u an idea...
My brothers street driven 300kw circut/drag evo3 gets motul fully synthetic gear oil for transfer case, gear box and rear diff about every 1000km, at 130$ per change apexi oil filter at 36$ and motul fully sythetic engine oil every 3-5 thousand km depending on how its driven at about 130$ per 4l
.
Some people might not agree with this post - that is fine - you can keep your hating to yourself, this post was designed to stir some thought with those who want to learn from the experience of myself and of a few others who have spent 10,000's on driveline and engines alone, and this experience has taught me otherwise!![]()
