That's a trick used by a lot of Jeep owners as well...probably not in the 50/50 ratio though.
Mk4 Golf TDI Estate 4Motion, remapped 1.9. Sweet runner = keeper. She is the 66th vehicle I've owned and hopefully, the last.

yeah, it's all done to how the owner uses the vehicle really. a lot of 4x4 drivers don't really push them that hard or don't go off-road, so they can get away with a thinner oil, and improve their fuel economy to :nerd:

A bit more information I have discovered while trying to find the correct oil for the Golf - make sure the oil is 75w90 grade and conforms to the GL-4 specification, NOT the GL-5. This is possibly the reason for the problem with difficult gear changes that are described above

As I mentioned earlier, just use the genuine VW oil. The cost savings and potential hassle don't make searching for something else worth while. I had considered getting rid of my 1.8T because the gear change was so poor when cold. No issues at all now with gear changing and so by the end of this year I will be into 20 years of ownership. I am amazed at the difference the correct oil makes.
