2010 1.8 TFSI Transmission and Differential Fluid Chage
I bought a 2010 1.8TFSI Audi with manual transmission.
To have a smoother drive I decided to change the diff and trans oil which I do at every car without any issues.
The sticker under the bonnet says that TAF X oil for the manual transmission.
I have 2 questions:
1- I had a research on google and found out that TAF X stands for Castrol 75W90 GL4 oil is that true?
2- I could not find any info in regards to the Differential Oil type of this car? Should I use 75W90 GL5 or 80W90 GL5 or something different for the differential?
Look forward to hearing from you all.
