"Never exceed ... 10000 miles ... between oil change intervals" is a quote from the owners manual for my 2015 FFH. Taken literally, it means you can't go over that 10,000 mile oil-change limit by even a few miles, much less the "500 miles plus or minus" I used in all my previous cars with their oil change intervals. Does anything over 10,000 void the warranty? I ask because I'll have about 9400 miles on the oil before I take an 1100 mile trip next Wednesday (500+ miles each way plus some driving while there). I'll be in danger of going over the 10,000 mile mark on the trip there. So I guess I should get the car serviced before I leave, right? Seems a bit of a waste to not be able to go to 10,000 then get the service reasonably soon after that. More than a waste, it removes the "even 10,000 mile numbers" as the triggers for an oil change, since each change (to satisfy the manual's requirement) would be at somewhat less than 10,000 miles and each change would be "lower down" from the next 10,000 mile mark.
