Sounds like somethings a miss to me.

I did a 500km+ day on my Ten, nearly all of it on the motorway sitting at between 65mph and 80 and it didn't used any oil really, Little in the airbox drain but nothing to need draining out.. That was on a loaded bike too. My bike has 9000 miles on it and doesn't use any oil between services.

If water has got in the engine and mixed with the oil it will have made the oil go white and creamy, As for the oil use
