Poll on adding oil between oil changes

[paulofto]

2003 S with 83,500 KM (~52,000 M). Change oil every 7,000 KM (~4,500 M). Never add oil between changes except when the IMS Guardian wasn't quite tight enough after an oil change and I lost ~1/4 litre before retightening. LN says 19 ft/lb, I now tighten to 22 ft/lb. Original IMS and no signs of metal or debris when oil filter is cut open and inspected.

The only 'oil' leak I have is some weeping from the brass shifter bushing on the 6 speed transmission. Not enough for concern but I will look at it when the clutch is done in the future.
