Hi all.
I read some posts on here about this. All people seems to recomend 75w90 synthetic oil, usually gl5 type (gl4 is also available), that's what I have in the car since the lsd and clutch were fitted. I did some research now, and found that Ford recomends a specific 75w (not 75w90), in gl4 type, Castrol syntrans fe. It's a very different type of oil. What are your thoughts about this???
I probably will change the oil to the ford recomended type "75w", as the gearbox is too stiff since the last oil change. And will see if this works making the gearbox smoother. A friend just changed the oil in his subaru sti265 for a 75w90 gl4 type, and he says his gearbox is smoother now. Another friend in his leon cupra r225 will do the same, as his car is like mine at the moment with the 75w90 gl5, stiffer than usual.
