So it's been over 6 months since I last changed my oil with QS Green Bottle. I have only put on 2,800 miles in that time. Mainly, because I've been hitting the bottle and taking public transportation or riding my bike. It is a 2000 Honda Civic LX and I recently put in $700 installing new brake lines because of Chicago winters. I trust my Indy mechanic as I went to school with his brother. I live in a high density neighborhood of Chicago so my use is 95% urban driving. Should I change the oil due to the time? I used a Fram Tough Guard for a 4,000 mile OCI and now a 3,000 mile OCI. However, I hate to waste money. I have a Napa Gold and 4 quarts of Pennzoil High Milage ready to go. Many people say I have a reliable car but I've been putting in close to 1,000 a year in maintaining this beast.
