>>>>>>>>> i also cleaned the maf sensor but not the mobile 1. what weight oil did you use? i was thinking about replacing the o2 sensors but there are 4 for like 75 apiece>>>>>>>>>>>
Just found your reply post here, sorry it took so long to get back to you. I use 5W-30 Mobil I Extended Peformance oil and the filter I used is a Bosch High Performance Oil Filter. I used a better, longer life filter and the Mobil 1 oil to go longer between oil changes, 5,000 miles, instead of the 3,000 miles using conventional oil. I wouldn't change the O2 sensors unless you are getting error codes for them. I had two repair shops do diagnostic testing on my Ex to see why my gas mileage is only 10+ mpg city and they found nothing wrong with the engine or it's components and couldn't explain why it's that low. Some people in here have said it's because of the smaller engine, type of transmission and the weight of the vehicle combined that causes this, but some people with the same vehicle get 3-7 mpg better than me. I pretty much have given up on trying to get better gas mileage in the city, not gonna throw any more money at it on diagnostics and I've already replaced all the tune up parts that I could to make it better. It is what it is, a pig!
