Dear Tom,
I purchased a used 2007 Dodge Caravan SXT – V6 with 21,000 miles. It gets 19 MPG in the city and only 20 MPG in the country. What can I do to get better mileage? I follow your advice for maintenance and welcome your advice. Thanks.

Possible Causes of Scrubbing Noise in Left Rear of Car

Dear Tom,
There is a scrubbing noise coming from the left rear of my Toyota Camry LE. I had it checked out but they can’t find anything wrong. Please help! It sounds like some part is rubbing against another part. When I drive into my driveway it gets louder. When I am driving down the road, it is not as loud but I can still hear it.

Oil Consumption

Dear Tom,
I own a ‘94 Mitsubishi 3000GT-SL with 121,000 miles. At about 95 – 100,000 miles it started burning oil (no leaks obvious) with blue smoke in the exhaust on startup. In the last couple of months the oil consumption is rapidly increasing. On “general principles” I replaced the PCV valve recently to no avail. On a bulletin board for these cars, there has been talk of valve oil seal problems. Could the seals get to the point where they fail completely and oil consumption take a sudden leap?

Whining Sound in Rear of Truck

Dear Tom,
I own a ‘99 Chevy 1500 Suburban 4×4 with 102,000 miles. There is a whining sound coming from the rear when driving 55-65 mph. I had all the bearings replaced, and the ring & pinion gears show normal wear. Any suggestions?
Thanks,

Eddie from Miami

Eddie,
You failed to mention the rear pinion bearing. Have the lash and the up and down play checked for wear. Also, check the tire wear pattern on the rear tires. They could be cupped, which could also cause the whining.
