Car Tech forum: For HHR owners, questions!!

I'm back with an update on my 2010 hhr 2.4 auto transmission. It's february 25, 2012 and I am still loving my hhr. The mileage has gone up after I hit the 15,000 mile mark. I have now 20,500 miles on it. I am now getting 20-21 mpg around town and 33.5 was the highest on the highway trip . Went to pennsylvania 3hr drive going about 65 mph with 2 people + luggage. The only things that I had replaced was the heater fan motor ( which was a little noisy on low speed from day one ) replaced because it was too noisy , for I am a quiet person. ( bearings in the fan Motor ) . I have the warranty for 5 years, I figured I use it . It was free and took 1hour to replace. Just had the front brakes changed. I do alot of stop and go deliveries on the computers I fix. Otherwise nothing else has gone wrong. The 2.4 engine seems to have pick up some more horse power as it gets broken in . The other day I needed to get into another lane from a dead stop from a light , and I put the foot to the floor and burned Rubbber with my front wheels.I was shocked ! Its a good all around car / truck and I have fun driving it. Plus it gets good gas mileage. Now that gas is $ 4.13 for premium , I have down graded to middle grade at $ 3.87 every other tank. I call it my little blue toy .
