Before i bought my 1.9jtdm sw lusso the steering fluid reservoir was replaced and the fluid supposedly changed to Tutela g1/r at an alfa dealership 3 years ago, all itemised on the receipt. When i checked the level in the reservoir i noticed that the fluid was actually red, rather than the green i had expected. Looks like the dealership didn't use the correct fluid after all, or it was changed again subsequently. In a bit of a quandry now. Not sure if i should swap for the green stuff or leave as is. Steering works fine with no leaks or groans. Car has 114000 miles so am i risking getting leaks by changing to the thinner green fluid? Opinions appreciated.
