Another Aspect of New Vehicle Break-In

One thing I didn't find mentioned anywhere in this thread, is the break-in technique for the differential.

I've read a bit about from various places on the internet -- combined with some science background -- that state that a new vehicle's differential needs to be broken in carefully before being put under "full load" conditions (acceleration, towing, etc.). Basically you drive normally for about 15-20 miles, keeping it under 60mph, and then let the differential oil cool down completely. Continue this process for the first 100 miles.

By doing this, you negate what the "mototune" guy states on his website (have seen it before). I'm basically of the impression that small, high-strung engines (ie. motorcycles, etc.) need that type of break-in; street vehicles do not. I'd rather have the differential broken in properly -- which allows for the engine break-in to follow the owner's manual -- than vice-versa.

Just my opinion.

on the differentials the break in period is about 1000 miles to be safe . no towing or hauling. the first 200 miles no long drives. this is because the gear teeth have to break in . during this break in this causes the gear oil to get hot. so if its hot out then this adds to this issue. what can happen is the teeth will get brittle and can crack. so with short drives and keeping the speed down the first 200 mi should prevent this . then the next 800mi the teeth will be fully hardened/worn to mesh will little further issues causing the oil to heat up so you can start towing hauling ...

engine break in I always drive on back roads 30-60 MPH.. various speeds/grades the engine RPM is changing often and decelerating . the first 200 mi. after that then I will on the hywy slow down and hit the throttle to get the engine to accelerate at 3/4 throttle to get the RPM'S up so the pistons go fully up the cylinder walls then let off throttle and engine decelerate down to normal speed . repeat every 10 miles .

I have had engines go 380K miles and had no oil issues or engine work done. The engines made today are very much built with better machining . then with the synthetic oils used the engines if properly designed should last long , if the servicing is done at the proper time. I have noticed with engines made now little oil damage on the first oil change. back prior to 1990 there was a need sometimes to change the oil @1000-1500miles. oil would have a gray color to it and using conventional oils at that time.

I switched to synthetic oils back in 2000. no sludge .

Really great break in tips!


But this is a pretty old thread and Oil and Oil changes have changed a ton. Specifically with synthetic.

Blackstone and TBN do oil testing and more times than not synthetic oil has tested to be fine well over 10-15k.
I also don't see a need to change the original oil before 5k. The old concern of mettle filings and the special oil that needs to be removed before 1000mi is a thing of the passed.

I probably wouldn't go passed 10k even on synthetic depending on how/where i drive, but i see noting wrong with 7-10k synthetic oil changes for mainly normal driving (little off road).

Breaking in a New Vehicle
by Jim Kerr

I am asked this question at least a dozen times a week: "how should I drive my new vehicle to break it in?" Breaking in of a new vehicle is a straightforward process but there are many stories told about how to best do this. There is some truth in many of the stories but to separate fact from fiction, we should look at why we need to break a vehicle in.

A good friend often jokes that there is no such thing as "breaking in" a new vehicle - it is just the start of "wearing it out!" There is a little truth here too. The process of breaking in a vehicle means driving it so that parts can wear into each other. Usually, people think the engine is the only part that needs any break in period, but transmissions and drive axles also can benefit from a break in. So how should I drive the vehicle?

Start by avoiding heavy loads on the drivetrain. Full throttle starts, towing trailers, and loading the vehicle with heavy loads place extra force on all moving parts in the drivetrain. When parts are manufactured, their surfaces may look smooth but under magnification, we can see many "hills and valleys". Lubricating oil forms a thin film that separates moving parts so they do not touch. If there is a loss of lubrication or a heavy load placed on the parts, the high spots (hills) may push through the oil film and touch the other part. This causes wear.

The break in process allows the highest of these hills on the parts to wear down under light load so they do not damage other parts. As the parts move, they are polished so that there is less chance on high spots penetrating the oil film when a load is placed on the vehicle.

The manufacturing processes used today are light years ahead of vehicles from the 1960's and 70's. Component finish is better, internal clearances are closer, parts tolerances are more accurate, and materials are better quality. The thousands of miles needed to break in an older vehicle are no longer needed. Instead, it is the first few hours of operation that are the most important. By the time a driver has driven a few hundred kilometres, the vehicle is ready for regular driving.

When starting a new vehicle, engines should not be idled for long periods of time. Oil pressure is lower at idle speed and parts that depend upon splash lubrication may not receive enough oil to prevent high spots from pushing through. Full throttle operation should also be avoided. It places heavy loads on components and high spots can score other components, accelerating the wear. This doesn't mean you need to baby the vehicle.

Drive the vehicle as if you were trying to achieve good fuel economy. Light to medium throttle acceleration is preferred, and keep the engine rpm's in the bottom half of the rpm range. On many engines, this would be below about 3000 rpm for the first few hours. Occasional three-quarter throttle acceleration is fine, as the increased gas pressure in the combustion chamber helps the rings to seal.

Avoid "lugging" the engine. Driving in too high a gear at low speeds makes the engine work harder. It is better to have it running a little faster with less throttle than too low an rpm with more throttle. Modern engines don't need to be driven at slow speeds. Keep up with traffic and drive the speed limit. I wouldn't recommend towing a trailer with a brand new vehicle, but it is done sometimes and the vehicles seem to last well.

Some say that drivers should vary vehicle speeds during the break in period, driving only a few kilometres at one speed. This isn't necessary. If you are going to be driving on the highway, backing off the throttle every few kilometres and letting the vehicle decelerate for a few seconds will pull extra lubrication into the upper engine cylinders and intake valves.

Breaking in a new vehicle isn't a tedious or time consuming process. Drive it normally and with care for the first few hours and it should be ready for many more kilometres ahead.
Drive it like you stole it straight off the lot.

This is the procedure that I used for my 2021 4R TRD ORP.

Drove home from the dealer and with ~11 miles on it changed the oil to Royal Purple break-in engine oil. After ~50 miles I ran the 4R between 1,000 to 3,500 rpms keeping it very varied for ~500 miles. I then changed the oil and filter to the factory Toyota 0W-20 oil. I will do 5k OCI's going forward.

When draining out the break-in oil and examining the pleats in the oil filter - I did notice some very small metal particles. I am pretty confident the rings have seated nicely.

Also, it might be a placebo effect, but I don't notice the notorious "tick" that the current 4.0L V6 is know for. I do notice this "tick" on my 2019 4R - I broke that truck in following the factory guidelines - except for doing the first oil change at 2,500 miles.

ceramic coating for cars

Guys, bought myself a new car. Drove it around and realised I wanted to make it shiny for a while. I was advised to get a ceramic coating Calgary ceramic coating. I'm very careful with my car myself, but after washing it, it's not as shiny and beautiful. I already have friends who have all their cars coated. I am thinking of doing it too. A friend of mine does that. He says he can cover a whole car in 1-2 days. I have a Range Rover Sport now and I only drive around town. The process takes a while because it goes through final inspections by their managers before it is ready to go out the door. He takes care of all kinds of cars.

I have also heard of some car compaines put in special oil during your break-in and should not be changed early.

By the way, on the 3rd generation, the manual says the engine takes 5.2 quarts of oil with a new filter. I have found it takes around 5 3/4 quarts of oil. So if a oil change place charges you for 6 quarts of oil, they are correct and they are not ripping you off.
follow toyota's recommendations!
Just traded my 2016 trail at 176,000 miles

only changed the oil every 10,000 as recommended and it ran like new the entire time.
