hi all, looking to change the gear box oil in my A3 1.8T, 1997, its got 125k on the clock, whats the best to go for also any heads up on engine oil for it? as ive judt read a thread saying 5w-40 would be alot better than 5w-30!!! maybe someone could post up a permanent thread on all the oils for the A3 (8L) as its hard to find it. also how many litres both engine and gearbox takes. cheers matt.
