i need to change all the oils in my car.

i got a 54 reg sti type uk with dccd

want to replace gear box, rear diff and engine oil.

what is the best stuff to use and how much of each will i need?

 

5 ltrs syntrax for gearbox and rear diff.
engine oil 4.5 litres i use mobil 1

 

0w40 for engine?

 

i used 4.5 litres of 10w 40 Mobil S (semi synthetic)
GL5 transmission fluid for gearbox and diff 5 Litres in total

This is my own car setup (MY96 Classic) and is working well, i'm not sure if it will on yours though.

 

im unsure what oil to use. so any advice will be verry helpfull.

 

there are a million and one threads on oils here - have you tried searching?

 

might be a thought here just put in what your owners manual says to use
you see it time and time again on here about oils,every one has thier own views about it!!
all iv'e ever used is what is says in the manual to use and i have never had any problems.
just warm up your car before you start hitting the loud peddle,also warm it down properly and you should'nt have any bother with it
ps,i have an 03 sti prodrive.

 

Run syntrax in my uk turbo box but im sure its not recommended on a car with dccd.( castrol syntrax is semi synthetic)
