Warm up idle or drive and go?

On my way to work in the TL I literally have 5+ minutes of residential neighborhood streets before I hit the highway. I let the idle go down, usually 45 seconds and then drive it through the neighborhood very gently. Leaving work I let it sit there idling for a good 3 minutes because I have to get on the gas pretty hard as soon as I leave the parking lot.

On the GN, it has .004" piston to cylinder wall clearance. The first 45seconds to 1 minute are spent idling until the piston slap goes away. I put it in gear but don't drive it for a few minutes. With the 3,500 stall convertor it will blow the oil filter off on a cold start if I try and drive it right away. Once underway I drive it around the neighborhood a few times until oil pressure starts dropping off and I know it has enough heat in it. In the winter the warm up procedure can take 15 minutes and sometimes 30 minutes before I'm comfortable making any sort of hard pass.

The girlfriend on the other hand in her Murano has it in drive and is near WOT by the time she's releasing the starter lol. It physically hurts me to watch her drive.




Sounds like an awsome Grand National,love those cars!

Love the old Fox bodies too. Too many great races from the "old days" to mention. They were kind of like the GNs, you never knew what you were going to get until the light went green.

In Germany, a person can be fined for such waste.



It's good to see they've made some progress .




There are intersections in some cities in Germany which have an "engine light" (as opposed to a "Check Engine Light"

) which comes on with a red traffic light. When that light is on, you're supposed to turn your engine off at the intersection. The light goes out a few seconds before the traffic light turns green. They've had this sort of thing for years. I lived there for 9 years and you didn't dare idle your car for any longer than 10 or 15 seconds.
A great policy, IMHO.

I'm afraid that I'd have to break that law. Restarting a vehicle will use more fuel than idling for a few seconds.
 
May not but their would be excessive starter wear.

I usually just start my truck up, scrap the winshield, put my seat belt on etc... But if it's a really cold morning I'll have to wait for the defroster to clear the windshield so I can actually see.
 
I use an engine block heater I had the dealer install on my 2005 Subie Legacy Gt (Turbo) for when the temp drops below 30 deg (F). I use GC year round and let the engine idle for about 30 seconds before backing out. Then drive easy for about 2 miles before getting on the highway.
 
I usually just let vehicle idle for about 30 seconds and go. Our winters are pretty mild in Texas. When it's say, 40F or below I sometimes start and let car warm up for 3 to 5 minutes. I think that's probably more for my comfort than the car.
 
On both my cars if its a cold start (car has been sitting for more then 4 hours) and its winter I let them sit for a minute or two (one of my cars has a starter so I usually just start her up from the comfort of my home lol and put my shoes on, jacket get ready to go out and shes ready to pull away)

In the summer, on cold starts I do let it sit for atleast 30 seconds.

I know i may be wasting a bit of fuel but thats how I like to drive my car and so far it hasn't done any harm what so ever.
 
The most I will let mine idle is a few minutes if its frosted up and i'm late for work, I'll start it up crank the defrost, run back inside and finish getting my stuff together for work. If I don't have to do that, then I'll start it, wait 20-30 seconds then head out, but I don't have to give more than 1/8th throttle where I drive before the car is warmed up.
 
I let the fan die down which takes about 15-20 seconds the drive slowly. By the time i hit the freeway the water temp not oil temp is normal.

Actually, this is the daily routine for one of my neighbors who has a beater sing ray vette with a tired 350. If it's sunny, it gets driven around the block! Even if it's 20 degrees out. Sucker don't sound to good.

You should hear his Triumph Spitfire! ROD KNOCK.



I used to have a neighbor just like that when I lived in Minnesota. It would be single digits and before the starter quit spinning he had that thing banging the rev limiter(this was a newer crown vic). I helped him jump it off one morning when the temp was in the low single digits. I was standing next to the engine bay when it fired off. I literally dove for the snow bank in fear of being hit by flying rods,pistons. He would trade his car in every 2 years. I feel for the poor sucker who got one of his cars.

I used a block heater and magnetic oil pan heater in the winter when living in MN.

I have a neighbor that does the crank and go every morning. His driveway has a decent incline up to the street. He has to gas it pretty good to back the car out of the driveway. I of coarse do the 30-second warm-up idle and baby the engine for the first mile or so. Whenever we leave at the same time in the morning, I usually catch up to him at the 1st red light.

When it's really cold out tends also to be when I'm skiing. So the car will sit at idle for a few minutes while I load up the skis, scrape, etc. before I get in and take it easy for the first few miles until at least the temperature gauge is at normal.

Around town, I start it and then put on my seatbelt, fiddle with the radio, etc. for about 30 seconds, then drive easily until it's warm.
