Engines burn oil, but how much oil burn is normal is at the heart of a Consumer Reports study that examined nearly 500,000 new cars for how much oil they have to replace in their new car’s engine.

It’s a dirty, dirty business.

Hello Sajeev,

I was in contact with Mark Stevenson regarding my terrible, and unfortunately pretty common situation. I am post DUI (sadly not my first), but have quit drinking and am well on the road to recovery. I live in a city that does not have transit that will get me to work on time and therefore require a car to get there. (Read More…)

That moment you realize the oldest car in the parking lot is yours.

Yeah, I just had that moment.

The car in question is a 2001 Honda Accord EX. Four-door. Five-speed. A dodo bird of a used car stuck in today’s finance driven market. I walked around the parking lot you see above trying to find one vehicle, any vehicle, that’s as old as mine.

The blue ’05-ish Caravan on the bottom left came a bit close, but it didn’t happen. Instead, everything else seemed to be on the younger side of the curve, the overwhelming majority of vehicles sold new at a later time in history.

Hey Sajeev,

Long time reader first time writer. So here is my dilemma.

I have a 2007 Mazda 3 sedan 2.3L with a 5 speed manual that currently has 97,000 miles on it. It is modified with a Mazda branded CAI and cat back exhaust. It’s been a pretty much trouble free car for its life. I’ve always maintained it in terms of tires, brakes, suspension, and oil changes every 4,000 miles. This summer I recently even took the car round trip across the country. Before leaving for that trip I had the power steering fluid, brake fluid, and coolant fluid flushes and new spark plugs. I also had the strut mounts replaced and the rear shocks done.

So after getting home from my cross country road trip I let the car sit for two days. When I went to start it up it would crank a bunch but no start up until I cranked, stopped, and cranked again. The mechanic confirmed my suspicions when he said it was the fuel pump, more specifically the check valve. He said replacing the pump could be close to 800-1000 dollars.

Dear Sajeev,

Back in 2005 I purchased a new Honda CR-V. It recently rolled over 200,000 miles. It has never given me any trouble or needed anything but normally scheduled service and the usual wear items (tires, brakes, battery). It has survived the New England winters rust free. Most importantly, it’s paid for.

Is there anything proactive I should do to keep it on the road, maybe even for another 100K? I don’t mind investing now if it will save me major repairs later. As trouble-free as it’s been I can’t see replacing it (nor am I in a position to right now), but given the mileage I feel like I should be waiting for that other shoe to drop! (Read More…)

The contrarian in me loves it when conventional wisdom is proven to be not so wise. For decades, even before the first oil crisis of the 1970s, motorists have been told that making sure that your air filter is clean is one of the ways that you can improve  your fuel economy. It’s intuitive to think that a clogged air filter will affect the way an engine “breathes”, how efficiently it can get gases in and out of the combustion chamber and how that might decrease fuel economy. That may have made sense decades ago, however it turns out that two different studies, one on gasoline engines and the other on diesels, performed by a team at the Oak Ridge National Laboratory, show that the fuel economy of modern, digitally controlled fuel injected engines isn’t significantly affected by the state of their air cleaners’ cleanliness. What made sense in the era or carburetors may no longer be applicable today. Apparently the engines’ ECUs working to keep emissions in spec are capable of leaning out the fuel mixture to account for a dirty air filter restricting airflow into the engine, resulting in insignificant drops in fuel economy. Though dirty air filters didn’t materially affect fuel economy in the modern cars, they did experience a decrease in acceleration performance so it’s still a good idea to replace a dirty air filter.

Abstracts of the studies after the jump. (Read More…)

My question is – when should I sell my current car? Our family runs a 2004 Pontiac Vibe with 109k miles. It is our only car and it seems to run better since it broke the 100k mark. It has been exceptionally reliable, cheap to own, and gets excellent mileage – I get 29mpg average! We like being a one car family and intent to keep it that way unless we suddenly become independently wealthy. (Read More…)

A few days ago I breathlessly described the highlights of old Porsche ownership – the immersive driving experience, the camaraderie among like-minded enthusiasts, and the opportunity to meet people through sharing the fun with others.  In a cliffhanger, I also hinted that there were some downsides to driving that type of car everyday… of course it’s not always halcyon days of empty roads and spirited drives.  I made that intimation for two reasons:  Sometimes the car can grate on the nerves of even its biggest apologist, whereas the remainder of the time it’s broken, with that same apologist’s wallet in peril.
