Here are two questions from a regular, and grateful, Piston Slap reader:

  1. How long is best to idle a gasoline engine after starting & before driving off: [A] a few minutes? [B] one minute? [C] until the revs settle down? [D] no need, just drive right off? Assume ambient temperature well above freezing; a shifting style on the sedate side; and a car made in the past 15 years so engine has EFI and EGR and all that. Current ride’s engine is naturally-aspirated and direct-injected, but I sure would appreciate knowing the proper protocol for other combinations too, if different. Several sources over the past years have all agreed on [D] for modern engines, but then just a few months back a Car & Driver column said [A], so now I’m unsure again.
  2. Leaving a car (stick shift *of course*) parked: best in gear, best in neutral, or doesn’t matter? Assume the parking space is either not sloped at all, or is sloped and I know enough to turn a front wheel into the curb toward the down slope. (Read More…)

I live on a private road that’s 3/4-mile paved and 1/2-mile dirt. Myself and a couple of others on this road park our cars at a wide spot in the paved section and use a high-stepping 4×4 pickup for the short ride between the parking spot and our homes, primarily because the steep dirt road alternates between an inch of dust in the summer and a couple of feet of snow in the winter, with slippery clay mud in between.

Sajeev,

Thanks very much for posting my question. Your answer and the comments from others were most informative. How about another?

We now have only 2 licensed drivers in our home. We do however have 3 licensed cars in the driveway. Please do not ask about the project car in the garage. 2 of the cars are our ‘daily’ drives, the 3rd is used primarily on weekends. We live less than 3 minutes from a 400 series highway in Ontario. That means that the cars can be required to reach highway speed before they are ‘warmed up’.

My normal practice last winter was to get up, start all the cars, turn off all possible drains on the batteries. Then take the dog to the park across the street, stretch our legs and let him do his business. After about 10 minutes we return. I then turn on the heater/defrost on the 2 cars that we will be driving and scrape/brush them. When this is completed, I turn all 3 cars off and go back into the house to get myself ready for work. You may all remember what last winter was like and the upcoming winter is supposed to be similar.

Now I understand that idling is environmentally irresponsible. And possibly against by-laws in some areas. That however is a discussion for another forum. (Read More…)

Sajeev,

I have a new (to me) ’08 Civic LX 1.8 liter, stick, bought with 35k on the clock. The previous owner was a woman who traded it for a RAV4 I think (I bought the car from a Toyota dealer). I’m guessing partly based on gender stereotypes that she wasn’t availing herself of the high revs to flog a lot of performance out of the car. (Read More…)
