Piston Slap: Parked in the Polar Vortex?
V writes: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? one minute? [C] until the revs settle down? 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 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.

Piston Slap: Improper Engine Warm Up Procedure?

TTAC Commentator Arthur Dailey writes:

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.

  • Inside Looking Out Why EBFlex dominates this EV discussion? Just because he is a Ford expert?
  • Marky S. Very nice article and photos. I am a HUGE Edsel fan. I have always been fascinated with the "Charlie Brown of Cars." Allow me to make a minor correction to add here: the Pacer line was the second-from-bottom rung Edsel, not the entry-level trim. That would be the Edsel Ranger for 1958. It had the widest array of body styles. The Ranger 2-door sedan (with a "B-pillar", not a pillarless hardtop), was priced at $2,484. So, the Ranger and Pacer both used the smaller Ford body. The next two upscale Edsel's were based on the Mercury body, are were: Corsair, and, top-line Citation. Although the 1959 style is my fav. I would love a '58 Edsel Pacer 4-door hardtop sedan!
  • Lou_BC Stupid to kill the 6ft box in the crewcab. That's the most common Canyon/Colorado trim I see. That kills the utility of a small truck. The extended cab was a poor seller so that makes sense. GM should have kept the diesel. It's a decent engine that mates well with the 6 speed. Fuel economy is impressive.
  • Lou_BC High end EV's are selling well. Car companies are taking advantage of that fact. I see quite a few $100k pickups in my travels so why is that ok but $100k EV's are bad? The cynical side of me sees car companies tack on 8k premiums to EV's around the time we see governments up EV credits. Coincidence? No fooking way.
  • EBFlex "I'd add to that right now, demand is higher than supply, so basic business rules say to raise the price."Demand is very low. Supply is even lower. Saying that demand is outstripping supply without providing context is dishonest at best.
