Hello,

I have 2006.year Octavia 1,9tdi with 5 manual gearbox.

Which gearbox oil you will suggest to my octy?

Buy it from the dealer. It's not too expensive and it is exactly the right stuff for the box.

If you can't get to a dealer, I have used the millers TRX Fully Synthetic 75W-90 in the box and it worked well.

I will however say that the boxes appear to dislike certain brands of oil, including some big brands, so if you can get to a dealer it is worth it.
