Lost about 4 to 5 mpg since last oil change . Started off about 2mpg average and has been increasing slowly since, brought it up to the dealer and they told me nothing they can really do about it as its super hard to diagnose but to test the oil when i change it again and let them know if anything abnormal shows up. gonna change he oil this week and up date to see whats going on my average mpg stays pegged around 30 now instead of around 39 to 42. Im averaging 37 to 39 where i was averaging 41 to 42 calculated by each fill up. Anyone got any idea it should have went up not down
Yes new tires are lrr. turbo was replace was leaking between the case halves sealed the system back up, advised its been leaking for a while and was probably the cause of the loss in economy
Covered under warranty fuel economy seems to have come back but i havent put much on it since power is back now. Ill post back after next week im doing a 1300 mile round trip next week
