Liqui Moly GL5 SAE 75W-90 Fully Synthetic High Performance Gear Oil 1L 1 Litre

While topping up the oil at that frequency may be annoying and possibly expensive, there is generally nothing to worry about. SAE Viscosity: 75W90. Quality: Fully Synthetic. Full synthetic oils last longer than semi-synthetics or mineral oils, so although they may cost more in the first place, a full synthetic can work out as a cheaper option in the long run.
