How Do You Break in a Car’s Fresh Engine?

Like AutoGuide.com on Facebook

So, you just bought a car, something showroom fresh with fewer miles on the odometer than a fresh pair of footwear.

Naturally, you’ll want to do everything you can to protect this investment. Decently violating the engine in will do its part to help ensure a long and trouble-free life.

But opinions differ on how this should be accomplished. Some experts advocate performing a hard break-in. This includes a certain amount of intense acceleration during the vehicle’s very first few miles. The objective of this is to force piston rings against cylinder walls so these metal parts can seat before the bores’ honing marks are worn away. Done decently, this supposedly results in an engine that produces more power and lasts longer.

Take it Effortless

Alternatively, most others recommend taking it effortless for a while, including many automakers. According to Michael Siegrist, assistant chief engineer of the fresh 1.6-liter turbo diesel engine in the Chevy Cruze and the man in charge of all GM’s passenger-car compression-ignition engines in North America, “Most of our vehicles ask that you do a 1,500-mile break-in.”

This encompasses several things. “Don’t drive a constant speed,” said Siegrist; attempt to vary the engine’s RPM frequently. He also added, “Don’t go over eighty miles an hour,” and “no full-throttle starts.” It’s also prudent to avoid exceeding Four,000 RPM. Sorry Corvette and Camaro owners, the break-in period is a no-fun, burnout-free, racing-exempt zone.

But in the long run, your patience during those very first 1,500 or so miles will likely be rewarded. “What’s indeed going on,” explained Siegrist, “[Is] you have machined parts with acute edges that during that break-in period, we’re lapping in those acute edges so that they fit ideally for the life of the engine.” He said internal combustion powerplants would operate fine with harshly machined components, but things improve after those moving parts get convenient with one another. “Once you do that, you’re good forever,” he added.

It’s a similar situation with Toyota. For its Highlander crossover at least, the Japanese automaker recommends right in the owner’s manual that customers avoid unexpected stops or towing for up to the very first five hundred miles. After that, driving enormously quick, all of a sudden accelerating or running at a constant speed for prolonged periods are discouraged.

Ready to Run

Naturally, suggested break-in procedures vary from one manufacturer to another. Generally, they seem to advocate taking it effortless, but that’s not the case with every automaker. David M. Goggin, marketing communications director at Cummins, a major manufacturer of diesel engines, said, “We have no special break-in procedures,” a policy he estimates the company has had for a decade or more. “[Just] get in and drive it.”

Goggin noted that with Cummins’ current manufacturing capabilities and the tolerances they’re able to hold, plus superior lubricants and better materials obviate the need for a special break-in. Additionally, during engine testing, “We can tell if there’s something wrong,” he added, and hold back a certain powerplant if it’s not ready to hit the ground running from day one.

Another vehicle class where taking it effortless might not be recommended is in the spectacle market. Mike Schropp, engine supervisor at Livernois Motorsports, a company that offers engineering services, vehicle spectacle products and more said, “Most of the engines we build here would be high spectacle and/or racing-style engines.” Accordingly, “The break-in process is pretty critical.”

What does Schropp recommend? Well, he advocates customers use the right-most pedal a little more aggressively than some OEMs, but only to a certain point. “Medium explosion to medium-heavy explosion is truly the best,” he said. This corresponds toughly to inbetween thirty and sixty percent throttle.

Of course, Schropp cautioned the importance of not overdoing things. “There are people that… want a truly hard break-in,” he said, but enormously high explosions and temperatures are not desirable, so be judicious with the accelerator.

Additionally, Schropp stressed the importance of avoiding extended idling, which can glaze cylinder walls, preventing the rings from decently seating. For this reason and more, it’s critical to vary engine speed during the early miles after a rebuild.

“The rings themselves actually oscillate on the pistons,” said Schropp. Varying the RPM, accelerating and decelerating “allows the rings to budge and cycle” for an optimal seal.

What About the Oil?

Further ensuring a decent break-in, Livernois Motorsports puts special oil in all its rebuilt engines. This is just another way of ensuring they suggest the best product possible to their customers.

For factory-fresh vehicles, this usually isn’t the case. Accordingly, Schropp recommends early oil switches to help flush any undesirable metallic bits out of an engine’s vital circulatory system. A lot of that cruft is “going to get caught in the oil filter,” he said, but still, “I would switch it after the very first thousand miles.”

The same isn’t necessarily true for automakers. “We manufacture all or our engines with the oil we want it cracked in with,” said Siegrist, lubricants that he suspects are not specially formulated to help with this process. Additionally, he noted that a more frequent lubrication service schedule is not necessary. “Just go after the oil-life monitor,” which is built into GM vehicles.

Still, you can never harm an engine by switching the oil too frequently. Early service like this, while most likely wasteful of money, can only benefit vehicle longevity.

Another thing that could speed this process along is avoiding synthetic oil. Schropp recommends this since you need a certain amount of friction inbetween moving parts for them to wear together decently. Man-made lubricants generally permit less of this than their mineral equivalents.

Final Thoughts

So, if you just had a high-performance rebuilt powerplant installed in your cherished one thousand nine hundred seventy Plymouth Road Runner, listen to the engine builder’s advice.

Likewise, as you drive off the lot in a factory-fresh car, crossover or pickup truck, it’s most likely best to go after the automaker’s specific break-in recommendations. Siegrist emphasized that new-vehicle buyers should read their owner’s manuals because everything is “spelled out exactly what to do.”

And curiously with many GM vehicles, whether it’s a lil’ Buick Encore, a diesel-powered heavy-duty Sierra pickup or even the ridiculously prompt Camaro ZL1, Siegrist said the break-in guidelines are largely the same. “Everything from an LT4 that goes into a Corvette or a little one-four turbo that goes into a Cruze, to our diesel, the geysers in those engines vary dramatically.” But he added, “We’ve kind of iterated to… a common treatment to the break-in.” As always, your mileage will vary.
