Just not enough dive time.
Just been out and bought 5l of Mobil 1 (bike needs an oil change) it cost £40, it was £48 in the local petrol station. Someone surely is ripping us off, when I asked why so much? I was told that the oil price had rissen (no sh1t - I work in the oil industry) but Mobil 1 is 100% synthetic oil - so how comes that's gone up too??
