Edging out a bit more? (photo courtesy: www.productwiki.com)
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.
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.

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.
For years, Bruce Lubin and his wife Jenny collected tips to save time and money, published on their whoknewtips.com website and their Who Knew? book. Here are some good ones for your car: (Read More…)
Flashes and pulses.
I was staring at an archaic diagnostic system on a 1992 Volvo 940 wagon. It was located underneath the hood, inside a plastic cover, with six little holes for each one of the six digits, along with a cheap plastic wand.
What came out was morse code. Three little reds, stop. One little red, stop. Two little reds, stop. Code 312. Time to visit the brickboard, where the code could be translated to about fifteen different potential issues.
21 model years later, and we’re still not quite there yet.
Public schools have the unique misfortune of being the target for every harebrained idea related to learning.
Why? Because everyone is an expert! We all have great ideas! In quiet surrender, many public schools are left with ideas that result in excessive paper pushing and basic rote memorization.
Don’t get me wrong folks. Higher order thinking skills are also valued in most public schools (outside Texas). So long as they are also far, far away from the neighboring political bonfires.
So with that in mind, why not offer one more good idea from us gearheads?
Thanks so much for the data on fuel additives. I did later determine that it also can be a salve for ethanol-afflicted soft bits in the fuel lines. Here’s the deal though. My little 1994 Nissan Hardbody is a delightful little vehicle. (Read More…)
