Hi all,

I did a 60k services at dealers and an oil change 4700 highway miles afterward. I notice my oil become very dirty and have sludges pieces that came out from the filter area, as well as lost of some horsepower. Since mine is an Auto I notice that it took me 200 more rpm to get to 80mph compare to before. Other than that things seems fine.

Do you think something is wrong? I have changed the oil to mobil1 5W30 and is wondering if the new oil will clean up the old sludge that may have build up over the extra 1000miles.

Thanks

 

i dont know if this will help your problem but it cant hurt, go to pep boys or autozone or something and buy one of those fuel system cleaners and pour it in your gas tank. maybe itll help you a little. also check to see if your throttle cable isnt loose.
