I have read that people got Castrol Syntrans Multivehicle 75-90, in their cars here in forums and it has helped improve gearchange.
I serviced my car here by a local mechanic, and I thought I would do the same but he wouldn't touch that oil as he said it was the wrong oil and i would ruin the gearbox. It was the yellow thick oil , he drained a little amount into a cup form the original oil and i was watery/purple/redish (auto oil).. So my question is what should we use in our transmissions? (it has to be castrol oil as I have used it in all of my cars with good results).
Castroll sugests Castrol Syntrans Transaxle 75W-90 , but it is rated as GL-4+ and in my manual form alfa it says GL-5 oil.??
Could anybody clear this up for me?
