I didn't mean to start any oil arguments. In the service record part of the manual the dealer (in Mississippi) was filling it with Kendall 20w50 so they apparently thought dino oil was OK. I have used the Mobil 1 0w40 for a year and a half, idling at 2 bar, with no indication of problems until now.

So something has changed. Either oil clearances have opened up - VERY bad. or the oil pump needs replacing - BAD or the sender unit needs replacing - Not so bad... hands stay clean. I have a sender on the way. and will let you know what happens when it is swapped .

Thanks again.

Tim
