I have a question about driving style that I’d like to pose to you and the B&B. Part of my highway commute is a steady 2 mile grade. With a running start of 75 mph, my 2007 Mazda B2300 slows to about 62 mph by the top of the hill when I keep it in 5th gear, with the engine turning about 2000 rpm. I can maintain 70+ if I drop into 4th and floor it, but I’m a cheapskate at heart. My question is, is it really more efficient to lug up the hill in top gear, or am I just kidding myself and doing irreparable damage to my engine? (Read More…)

Best from the West, young man,
The Boss has a pretty nice ’94 Escort LX wagon sourced by yours truly, and it happens to have found the sweet spot betwixt my picking it and her loving it. A grand for this one-owner handshaker and she’s managed to put about 23K on it in the last year — points of interest are far and few between here in Wyoming. (Read More…)
Thanks for your recent article about buying auto parts.
I recently bought a well used ’95 F-150 with the venerable 302 and Mazda five-speed.
When I say well used, I mean the engine has about 253,000 on the clock and sounds like it is on its last legs. I’m pretty sure I can hear the jugs rattling in the cylinders when I first fire it up, the idle hunts all over the place and it has about as much power as the Ukrainian president.
I’d like to put a new mill in it. The previous owner spent a lot of time and money doing everything but engine work. Where’s a good place to start looking for a used motor, or should I spill the coin to have this tired old unit rebuilt?

Hi again Sajeev,
Steven Lang’s post buying quality tools piked my interest again on getting myself an OBDII scanner. But which one is right for me? Even the Autel brand mentioned by Steve have readers ranging from $30 to the $350 Autel MD802 mentioned in Steve’s post.
I don’t plan on working on my cars much, just want to use more than onomatopoeias to converse with my mechanics. (Nice. – SM) (Read More…)
Engine downsizing is all the rage. Making the engine smaller increases fuel efficiency, reduces emissions and cuts vehicle weight. With ever tightening fuel economy legislation in the United States and CO2 emissions regulation in the European Union, mainline manufacturers are turning to turbochargers like never before. In 2009 just 5% of cars sold in America sported turbos, and that 5% consisted largely of European brands like Volvo and BMW with a long history of forced induction. By 2013 that number had more than doubled to 13%. Honeywell expects the number to rise to 25% in the next four years and the EPA tells me that by 2025 they expect 90% of cars sold in America to sport a turbo engine. With turbos becoming so ordinary, what’s a turbo pioneer like Volvo do to keep a competitive edge? Add a supercharger of course.
One of the best things at PRI is a little room, tucked just off the main hall, that usually houses the first-time exhibitors or late entries. This year’s “new arrivals” included an outfit called Midwest Supercub and Midwest Supercub’s line of homemade, alcohol-burning, CNC-milled racing engines. For lawn tractors.
Ford Racing quietly began offering its advanced, 2.0 liter Ecoboost turbocharged 4 cylinder crate engine earlier this year, without much fanfare. All that changed at the 2013 PRI Show in Indianapolis, however, with Ford’s Ecoboost powered 2015 Mustang twirling away on a giant lazy Susan directly under the giant “Ford Racing” banner mere steps away from the small crate engine, displayed proudly with its (relatively hefty) $8,000 price tag.
Dear Sanjeev: (facepalm – SM)
As a matter of coincidence most of the vehicles I’ve owned have been covered in previous Piston Slap articles and I’ve noticed a recurring theme: at one point, a point likely occurring far prematurely than hoped, I’m going to have an issue which according to your previous advice will require either a new engine or a whole new car.

I have acquired two VM Motori RA 428 engines that were pulled from new Chrysler minivans in 2009. The van were converted to electric drivetrain in LA. I want to install them in a pickup but because they were never installed in a truck from the factory, it will have to be a custom job. (Read More…)
I have a piston slap question for a friend at work. She drives an ’11 Mazda CX-7 2.3. For over a year she has had an issue with fuel in the oil. Enough that the oil level has been as much as 1″ above the full mark on the dipstick as a result (oil level was checked after service, and frequently between services). This is noticed within weeks of service/oil change. (Read More…)
