Is it fast? I''ve done 3000km on my used 1.5T Civic (27k km when bought, oil life 100%) and the oil life has gone down 30%. So about 1000km or 600 miles per 10%. I'm in a colder climate so that may contribute to it as well. Driving is 70/30 city/highway.
I'm down to 15% at 2100 miles I think it's because all my driving is short trip stop and go. My mileage is around 27mpg. 6MT/ 2.0. Also I have a lead foot. I'm thinking that the oil life indicator may not be very accurate depending on your driving conditions. My oil still looks good on the dipstick.
I'm going to change it today or tomorrow just for fun. I DIY my oil changes. I don't trust anyone else to do it. Once WAL MART stripped my oil plug threads and another time I had it done all my oil came out on the parking lot at the quick-change place. Even my dealer has 18 year-old guys doing the oil changes. At least if I f**k it up I have no one to blame but myself.
