Given the weather of late down on the southcoast, would you be concerned to find signs of Mayo on the Oil filler cap even after a long run (70 miles on the M25/M3). I first noticed it after leaving the car at Heathrow whilst in Thailand at the end of last month and put it down to the car not being used, however three weeks later there are still signs of Mayo on the oil filler cap but i'm not sure if it's because i do less than 20 miles a day and the engine isn't getting hot enough to allow the water to evaporate.
There is no noticeable use of coolant, nor is there a drop in performance.
