Hi. My 40K 2002 Carmy runs well although I have noticed a slight loss of mileage performance in town driving (Los Angeles) at around 17mpg (long distance freeway seems to remain at around 29-30mpg).
During the last oil change, the dealer suggested a "Throttle Body and Fuel Injection cleaning".
1) Is it really necessary or is it just a way for them to make money 2) They charge $180 while Midas only charges $90. Does the dealer really do something different? 3) Should I stop doing the oil change at the dealer anyway? They charge about $80 when you could get an EZ lube synthetic oil change for about the same price. 4) Does Synthetic oil even bring any benefit considering I do change the oil regulalry?I would appreciate anyone's thoughts on this.
Thank you,
FD
