I'm a europoor and I do the second one (albeit not for 5 fucking minutes, just until the rpm goes down)

I idle my engine to warm it up, and I prefil oil filters if they're installed vertically.
I don't go around telling others that they should irl.
I could rant about thermal expansion of metals but I'm going to lunch.

>>28961685
Other than double clutching, everything on this list is a good idea. 1/10 bait.

>>28961697
>I could rant about thermal expansion of metals but I'm going to lunch.
Okay so you're aware that your engine tolerances are designed at operating temperature and by idling you're taking significantly longer to warm it up to get it up to operating temperature, which increases wear.

And because your engine is cold, it runs rich to compensate for the air density and o2 content in the air, and because gasoline is a solvent, its washing the oil off the walls of the cylinder.

Tldr: You're causing more wear than just by driving lightly.

Number 1 is real for 90's fuel pumps, they really need to prime.
And 3 is good for saving yo shit when skipping gears.

>>28961718
3 eggs over easy and grits ahh yeah that's lunch.
Anyway, I disagree and will continue doing it my way. I wait until the idle drops below 1k, then drive lightly until it's at operating temp.
In highschool I had a 90s Eclipse with the 420a (dodge/plymouth) engine. Aluminum head, cast iron block, with just a copper gasket between them. Due to thermal cycling this bad boy already had a blown headgasket under 10 years old and I replaced it with a fancy german multi-layer steel one, but it's very common for that engine. I'm not saying that's normal, but thermal expansion isn't a myth only nerds care about.
IMO putting load on the engine when it's not warmed up is worse than letting it idle for a bit.

>>28961685
'pends on the vehicle
with my daily i shift into d even before the starter has fully disengaged
i'd idle my sports car tho, to spoil bystanders with my power ballad (v8)

I prefill my oil filters, but that's the only one. Not sure if it matters, but it's easy to do and gives me a little piece of mind so why not?

>>28962309
Based. I'm not even exaggerating. Broccoli hair kid at work who drives a VQ insisted he warm up his car for 10 minutes so he could move it 30 feet because he wasn't in a real parking spot
(It was just below freezing with a light snow and the plow driver needed to clear the area he was blocking)

I tried explaining too him I been watching engine rebuild videos for years and been into cars before his dad creamed inside of his mom but he looked at me like I was talking out my ass. I even double downed and explained it's a passenger car. He could have just put it in neutral and pushed it the 30ft and it would have saved his engine some wear.

>>28962309
I worked in full-vehicle testing for an American manufacturer. We had a rule that you couldn't start a duty cycle until the engine temp had flatlined for at least 5 minutes.
I'm pretty fucking sure that making a cold engine lug 3,000+ lbs around is worse than idling it. But you do you. ;P

>>28961685
Last year I was taking care of a Toyota Corolla from 91. It was in bad condition so I was instructed to start it once a day. To do so I would have to idle it for 2 minutes otherwise the transmission would make the engine stop. As a bonus I had to disconnect the batery since it was a weaker battery than needed and the car would drain it. Really miss that car.

>>28962983
When I still had my bile, I had the impression that the engine ran best, when I drove it moderately (or idled it) for a while Andrew lthen turned it off and let it rest for a few minutes.
It felt as if the bike had more power after that.

I prefill oil filters especially cartridge types

>>28961685
My car's manual says it's recommended to idle until the temp gets up to the C mark so that's what I do unless I'm in a hurry. I also don't get it over 3k rpm until it's reached operating temp.

>>28961685
I don't prefill the filter, but I always lube the rim of the filter with my finger. am I guilty?

>>28961835
>IMO putting load on the engine when it's not warmed up is worse than letting it idle for a bit.
I just told you why putting a light load on the engine is better than letting it idle. Idling puts next to no heat into your engine, yet the fucker is revving at 3000rpm to heat up the cat, all while completely out of tolerance because its cold. Its bad for the engine. Just drive lightly until its warmed up.

And I just told you why letting it idle is better than putting load on a cold engine. Do you want to run it a little rich or put 3,000 lbs of load on it when tolerances aren't to those the engine is designed for? Idling is considered harmful in the sense that cops cars do it heat soaking for hours, it has nothing to do with warming up an engine.
This is AI, but it's more than no pic.

i double clutch to go into first because the syncros are fucked

>>28963133
>I double clutch to go into first because the syncros are fucked
Even with syncros on a new car, getting into first is difficult without double clutching.
Chances are, you can roll away in 2nd unless you're fully-stopped anyway.

>>28961685
Idling your car to warm it up is bad for engines.
It takes 10x the time idling to full temp compared to driving.
Idle your car for 1min then drive it.
Oil doesn't reach it's peak protection until around 160F.
Idling will take fuck as forever for oil to reach 160F.

>>28963157
>It takes 10x the time idling to full temp compared to driving.
>Running an engine with poor tolerances will warm up faster if it's hauling 3,000-5,000 lbs of load.
Yeah sure. Warming up faster is clearly the only factor here, right?

you can still start a push-button ignition with a dead key fob, just press the button with the key itself and the RFID will still work.

Yeah, that's how I start my Wrangler. I don't like it. My real car is just a key that looks like a housekey, and I turn it.

>>28963161
Yes, the biggest factor is the warm up.
Driving warms up engine coolant and oil at a way faster rate.

>>28963177
You know, if you start up the engine and bounce off the rev limiter - it'll warm up faster than idling. Apparently you think that matters so go for it.

>>28963165
>Turning a key

Would you explain to me why you like push button start? Your car can be hacked and remotely started or shut down by criminals or by the government.

I use a key and none of that can happen.

Like what are you gaining from push button start? What's the appeal?

>>28963178
Bad Bait M8

>>28963181
No, it isn't. Different metals expand at different rates. Are you going to make it push 3500 lbs or let it go through the programmed cycle to idle to operating temp?

>>28963181
For the record, when you can't imagine that your fellow white man can do engineering, you kill us all. Why would kids go into engineering when it's hard and no one believes a damn thing you've done because you're white? Your attitude causes the problem more than engineers do.

Why is this obviously lying moron still peddling his non sense faggotry.
Yes, it totally better to idle in cold, poor tolerance conditions while washing the cylinders down with solvents for 10m with a greater cumulative amount of RPMs than doing very light driving at near idle RPMs to get to proper operation conditions faster. Totally.
We don’t drive carbureted cars anymore gramps, high idle only exists for the catalytic converter, not for engine wear.
>>28963187
>through the programmed cycle to idle to operating temp?

Its actually just to help warm up the cat converter faster for emissions purposes. But the timing is pretty much on point with oil bring properly circulated.

>>28963226
>What the fuck are you talking about? If I see you in my vehicle compliance testing lab for the Federal dept I work for, I swear to god I will
The cycle is for heating the cat, but it's good to use as a measure of warming the car. My last car even had a blue light on the dash if coolant temp wasn't high enough.
I don't give a shit, I've run EPA tests. The EPA doesn't really test cars, they let manufacturers do it. I Planned em out, did correlation studies. I did data aq, programming, and gave long ass reports to the EPA with visual evidence of our methodology and the math used.
If you think making a cold engine lug around several thousand pounds is better than letting it warm up at idle, then you are the fool.
You can say "my car is fine, I do that" and I can say the same. It's a nuance.
To be consistent we warmed up the engines, starting a cycle at some random point during warm-up adds another variable. Science, you want to minimize variables.

Nta, but if you use a spectral / frequency analyzer app and push a remote key you can pick up the signature of your remote. I think most are seeded so it changes every time you use it, but not sure.

Gotta use the histogram view. Your phone can hear car remotes. All someone has to do is replicate the signal. I’d show you an example but my car uses a house key basically. The apps are free, pop up the histogram, press your key fob buttons, and you’ll see it.

it's already overcoming resistance from the valve train, gearbox, oil pump etc.
lack of pressure is what kills engines because then parts are touching each other instead of riding on a film of oil.

>>28963921
the rev match, that's the main reason for double clutching

>>28963773
No, if I have to change tires I just take it to a shop. I considered that cheap harbor freight tire changer but I don't want to risk it.

I've done annoying time consuming work on cars for marginal benefit. But the stuff in the OP is annoying and time consuming and has no benefit.
