In warm weather, I generally warm the car up until the revs go down from high idle, just to get the oil circulating before I add stress. In cold weather, I like to wait till the coolant temp needle twitches on the car. I live in an area where -40 is more than possible in the winter.

[@mikep490]

Idling to warm a car went out with carburetor freezing. Many car makes say to NOT warm your car, just drive easy. The car warms quicker and you don't waste fuel. At those winter temps you probably have block and battery heaters. Keep them plugged in. (I installed a small room heater in my 70's VW van for cold days, switched on as part of getting ready for work.) For cold weather it is necessary to warm a car if the windshield will freeze over, but that's not just cold, it's sub-human. BTW, "wind chill" or "feels like" temps don't affect your car.

If you fill the brake fluid reservoir just before a brake job, expanding the calipers for the new pads will push the fluid out out of the reservoir for certain. I made that mistake myself. Brake fluid level is dependent on wear level.

[@anvilsvs]

Use a turkey baster and remove the fluid form the master before pushing the calipers back. Then remove it again after all of the calipers are back. Fill with fresh fluid and bleed each wheel until the fluid runs clean. Then change the fluid in the master every year when you change oil. That helps remove some moisture from the system.

[@J.R.in_WV]

Great video wizard! I do have one thing to add on topping off fluids though, I always advise people NOT to top off the brake fluid if the system isn’t leaking because to me the fluid level in a sealed system is a great wear indicator, plus if you top it off and the pads are at 25% when you go to change them you’re going to push brake fluid all over the place.

Failure to follow these recommendations may result in shortened engine life and reduced engine performance. • Avoid driving for long periods at constant speed, either fast or slow, and do not run the engine over 4,000 rpm. • Do not accelerate at full throttle in any gear. • Avoid quick starts. • Avoid hard braking as much as possible.

Myth #2 My new 2007 VW Rabbit 2.5L 5 cylinder engine had a special break in oil that was not to be changed until 5,000 miles. The owner's manual also recommended not using full throttle until 500 miles. And to avoid continuous steady rpms for more than a half hour until 1,000 miles. I followed these directions and even at 125,000 miles the car burnt less than 3/16" of oil on the dipstick per oil change. My oil change interval was 7,500 miles after the break in period. The owner's manual called for a 10,000 mile oil change interval, but it seemed too much for me. The vehicle I had before was a 1990 Ranger 4 cylinder. I changed the oil every 3,000 miles in that little truck and had to add a quart every 900 miles due to it burring it. lol.

[@lexus_offroad_adventures]

With engine break-in I would disagree and just say “it depends”. Safest bet is to just follow the manufacturer’s recommendations. We picked up a Porsche GT4 from Stuttgart in 2016 and they told us that, while they recommend staying below 4K rpm for the first 1k miles, the most important thing is to keep the engine speed variable and to not let it sit at the same revs for too long. (Something to do with the rings forming a groove at one spot in the bore) That’s direct from the engineers. Jason from Engineering Explained did a great video on this subject too.

[@chrishernandez2490]

Yes! I kinda see what the car wizard is talking about, and yeah of course ignoring the break in procedure will not cause the engine to blow up immediately. But Im almost certain if you tear down a properly broken in engine, vs one that was beat on from day one, the broken in one will have noticeably less wear. (This is just my guess honestly. 🤷‍♂️)

It's really more about changing the oil a couple of times in the first few thousand miles. You want to get all the particulates out that can lead to later damage.

[@Harmonic14]

In normal temps, that's called cat light-off. The engine idles higher until the catalytic converter is hot enough to be in its most efficient operating window. Regardless, you're better off driving lightly right away when it's cold. It builds heat faster, so you spend less time operating the engine in a cold state.

[@MrR2185]

I live in a cold winter climate and do the same thing. I am blessed to have a remote starter which makes that easier.

[@norfolkngood8960]

[@discerningmind]

True. You don't have to warm-up a gas engine, but you do have to drive it gently when it's cold by driving with the engine around 2000-2500 RPM's or lower. Driving hard and fast when the engine is cold can blow a head gasket, and that's an expensive repair now a days. Also, generally your engine is not fully warmed-up when the temp gauge first hits the normal mark, as fully warmed-up from a cold start takes about fifteen minutes of driving AFTER the temp gauge hits the normal mark for every part of the engine to become fully warmed-up.

[@alexanderflack566]

Yeah, I strongly disagree with his argument that if it were an issue there would be lawsuits. If (for example) your turbocharger starts to die at 100k miles because you wrung it out with the oil still cold, how could you possibly prove the cause? All you know is that the turbo died at 100k miles, well outside of most warranties. Yet, if driving more conservatively before your oil is at operating temperature allows it to last to 150k miles or farther, isn't that worth doing? Nobody is winning a lawsuit against the manufacturer either way, and I would much rather have my engine components last that much longer if the only thing it will cost me is a few minutes of patience each time I start driving my car when it's cold. I'll also point out that Jason at Engineering Explained gives a good explanation for this particular issue: kzbin.info/www/bejne/mqqoipSEa76SfK8

[@sunking2001]

About warming up the engine...something important was left out. Everything I've read and heard about...it is always a good idea to let the engine idle for at least 30 seconds or maybe up to 60 seconds to allow the oil to circulate around the engine...especially in cold climates. Every part needs lubrication inside the engine...give all those parts some oil before taking off. I think that's a "no-brainer."

[@robertmoore4637]

I’m with you on this. I’m sure wizard wont see this post. I have an 03’ 5.3 chevy with 545,000 and still drives fine. Burns some oil on start up (valve seals). What I have done to this engine is….

[@starboard9551]

If you have a turbo charged car it's best to let it warm up for a minute or two to build up vacuum pressure inside the engine and also don't go over 3,000 rpm until the engine reaches full operating temp. Just because you can hit the push start and instantly slam it to 6,000 rpm doesn't mean that's good for the car and if you do that on a regular basis you will cause significant internal damage in the motor and possibly the transmission if you actually put the car under load. Turbos are somewhat of a paradox being that they are both stronger and more powerful than a regular engine, but at the same time they are more fragile and delicate.

[@richardbutton1179]

Im old enough to remember a car was considered worn out at 50k miles. Not the engine or transmission, but the rest of the car was considered wore out. And if it was close to 100k miles it was considered "ready for the scrap yard" even if it was still running good.

[@brianeickholt3381]

The one thing I remember hearing about warning up an engine is to remember that the transmission is still cold and drive more gentle for the first mile or so until the transmission has warmed up.

[@kc9scott]

I’m pretty sure a transmission (at least for a manual) takes a lot longer to warm up than an engine. I’ll happily wait for the engine to warm up, but for the transmission, I don’t really have any extra patience. If it’s an auto trans, they usually cool their fluid through the radiator. During warmup, that cooler will probably act as a transmission warmer, with the two of them basically warming up together.

[@mattheweburns]

Don’t top off brake fluid either, it will just make a mess when you install new pads/rotors… I’m curious about what I have read online as “fact“ that with an older engine with many miles on it that has some seepage switching from conventional to synthetic is not recommended because it can cause existing seepage to get worse. If the weight is the same it doesn’t seem that it could make a difference but then again consumption by seepage with conventional could burn and form a crust/scab somewhat covering up leaks?

Glad he speaks about brand new break ins. Manufacturers typically test engines before install, thus breaking in for the most part. Motorcycles, however, have very mild test phases, at least Japanese ones for sure, and so require some special break in procedures.

I've had reasonable mechanics in my lifetime and I've heard a lot of these being debunked by them, but also would like to add is not to top off brake fluid. That's the easiest way to check the wear level of your brakes, if you top off and then go to change the brake pads, the fluid will overflow when you compress the calipers.

[@plonkster]

The way I drive my vehicles, the brakes usually last longer than the brake fluid (which is hygroscopic and needs a flush every two years or so), so I end up replacing fluid before I replace the brakes. That means that inevitably I end up with a full brake reservoir halfway through the brake wear.

[@Knotyourbusiness]

I recently started to check my oil every time I fill up. An older coworker of mine told he always did (we are both maintenance technicians). He kept his vehicles in immaculate condition. It is a good habit to have. I know what it's like to run a Chevy Luv pickup truck out of oil on the Interstate and lock up the cam. I know what it is like to run a Kawasaki 440LTD low on oil and wreck the engine -also on the Interstate. Checking the oil at each fill-up may of prevented those mistakes.

They adjust for fuel and will advance the timing based on the fuel you put in.

For #2: some cars are electronically torque limited now for the first X miles for their break-in period. The C8 Corvette is one that comes to mind. For #5: if you have an old car that always ran conventional oil, the gunk build-up over time can act as a seal, and the detergents in synthetic oil could break down the gunk seal enough to cause leaks. Other than that, it's fine. For #6: Don't top off your brake fluid. If you're low on brake fluid, you either have a leak or your pads are low. You should get brake fluid flushes every few years or so like he says in #8. For #8: Go by your owner's manual for oil change intervals. The manufacturer did hundreds of thousands of miles of durability testing, so they know better than the guys trying to sell it to you.

Just in case anyone checks on this, and wants to know: most gas these days is cut with ethanol, it’s a way to bump the octane safely. The reason it SOMETIMES can be dangerous is because old fuel lines can be corroded by ethanol, as far as functionality it’s fine. Most fuel lines in cars these days wouldn’t be impacted, even if they’re a gasoline only, because they are prepared for that corrosion. But on older stuff it can certainly be a concern.

[@Timberland1963]

I think it’s a good idea to let an engine warm up long enough to get the oil flowing enough to start lubricating the top end of the engine. When it’s well below zero it takes a while to get the oil flowing even with a good synthetic. Your oil pressure gauge will read higher than normal until things get warm and moving. I totally agree that you can start a car up and rev it right away and it won’t blow up but you’ll definitely be doing an overhaul sooner than if you gave it a few minutes to warm up. When I was a young lad learning about engines I was told pistons are slightly oval and cylinders are round. As the engine heats up the piston will expand and become round to fill the cylinder. I don’t imagine that has changed since metal still expands and if there’s no place to expand to then there will be rather severe repercussions. If you abuse an engine you will pay a price eventually. Also the Wizard should know that some engines do require a break in period and in fact there are a few where the computer will keep power and revs down until the engine has a certain number of miles on it. I’m thinking all those 700 + Dodges are like that and they will not allow the use of launch control until they have a break in period.

[@aaronrunalls375]

And Corvette

[@mikep490]

Agreed, but the time is seconds. A Toyota 4 cylinder engine model graphic showed, after oil change and with an empty filter, it took 12 seconds for full pressure. Agreed again about not revving, preferably until at operating temps. For break in it's best to follow the mfgr recommendation. I doubt anyone does. Mine said to drive moderately for the first 60 miles, then I could do 50 or 55 MPH for the next 240 miles. That's maybe OK when you didn't buy your car 150 miles from home; break-in half complete. I simply drove home with a light foot and mostly stayed with the semi trucks. Break-in oil used to be a "thing" until the 80's. Drive maybe 2K miles and the dealer would change the oil free of charge, along with adjusting the carb. (1978 GLC, my first new car.)

[@shitloveaduck]

I live where it can get really cold, -45 at worst without wind chills. On anything fuel injected (modern, not like the old mechanical systems, I will let it idle about 30 seconds n temperatures above freezing and a minute below freezing. With carbureted engines I double that unless it’s extremely cold (-18C or 0 F). When I can, in winter, I will idle the car long enough for warm air to start out the vents and you get to know how long that takes as each vehicle is generally different. These are for my comfort & peace of mind. Certainly are not scientifically based!! 😂😂 I have heard all the myths over the last 50+ years I have understood about vehicles. This is how I have formed my opinions. I definitely don’t subscribe to 3000 mile oil change intervals!! Some of the older vehicles I have or had, that was true when I drove them enough, otherwise I changed the oil annually. Today’s engines are different and can go some really long times between changes, depending on how you drive. I used to have a 1.5 hour commute, each way, for work. It turned out to be nice because by the time are home, work is out of your head (mostly). I went to the maximum intervals except in winter. In warmer weather the drive was easy on the vehicle. I didn’t drive beyond the speed limits (retired LEO) and so the engines just weren’t stressed. I live where trucks work best as there was always about 20% driving on gravel roads and the vehicles were 4wd. I burned a lot more fuel than in a small vehicle, but the roads beat those things to death. I changed the air filter more often than most people would think. I had vehicles with 320,000 km (200,000 miles) on them and the oil barely changed colour in them between changes, some change in colour but almost never black. I had a Mopar 3.7 V6 that was another story,,,, right from new, it was black 3/4 of the way between oil changes. The dealership said that was fine, but after 200,000 km (125,000 miles) I just wasn’t wanting to be stranded with a blown engine. It was otherwise great & the only smaller vehicle (2007 Jeep Liberty) I had that lasted well and wasn’t rattled to pieces! 😂. The guy I sold it to still has it. Saw him the other day. He is at 350,000 km range and still no issues mechanically, but the electrical is not as good. He is shopping for another good used vehicle.

Good point on checking the oil level. Owners don't check and many oil change places don't check before changing, so you may not know if your car uses oil. My 2018 manual says "Check the oil level at regular intervals, such as every fuel stop." This is the same mfgr that says using a liter every 1000 miles is normal. I check oil after each change (even if dealer changed) then at 1500 mile intervals... more often if there's any sign of oil loss. (Currently none between changes.) Of course, it has a 4 quart capacity, hydraulic variable valves and a turbo, so losing a quart is a bit more serious than some cars. I'm surprised at people on chat groups, "My car has a knock. I added a quart of oil and it's not on the dipstick. What do I do?"

When the engine is cold, the oil is thick and the pressure goes high with high rev. If you have a pressure oil gauge it's easy to see. The abnormal oil pressure will stress all the gaskets and will not fully reach each component. Btw, even when the water temp reach normal, it will take some time until oil reach normal temperature. In a normal car, the impact can be low, in high performance car, it can be dangerous.
