Workshop: 5 Things Not To Do With Your Brand-New Car

If you want to get the best break-in for your brand-new car for 2020 and for the years to come, these are the things to remember:

1. Don’t floor it: When an engine is produced, the tolerances are tight so that its gradual use during the break-in period smoothens out the imperfections between the cylinder bore and piston rings. This in turn allows a good seal between the parts inside the engine. As a rule of thumb for almost all vehicles, it is recommended not exceed 4000rpm. Vary up the rpms and loads on the engine.

2. Shift conservatively below the redline: Reaching redline alone will cause uneven wear and tear to both the cylinder bore and piston rings. Staying there prolongs the damage. Instead, shift at low rpms to allow gradual smoothening of the contact points between the parts of the engine.

3. Don’t use cruise control: One of the biggest temptations when getting a brand-new car is to take it out on a long road trip to far off locations. This scenario will most likely keep the car at a constant rpm and load for a long time. This in turn will cause a constant set of imperfections to remain between the cylinder bore and pistons, so it is important to vary both the load and rpm to maximize the break-in period.

4. Make the car accustomed to operating temperatures: When breaking in the engine, the best condition for it is when it is at working temperatures. Not only does this allow the oils and fluids to cycle around the car completely, it also allows the critical parts to expand to their final state.

5. Avoid towing: Towing should be avoided because of its extra strain to the engine, it is also because the tires and brakes have to be broken in as well. For tires, there is a protective film that must wear off before they can achieve their full grip traction potential. As for the brakes, it takes a while before they achieve full braking capability.
