As a general rule, new or rebuilt engines should be run in for the first 500-1000 miles. The first oil change should occur after the first 300 miles or so.
What happens after engine overhaul?
So what happens when you rebuild an engine? A rebuilt engine involves removing the engine block from the vehicle and completely disassembling it. Once it has been cleaned and inspected, damaged parts are replaced with new or refurbished parts. All new gaskets, seals and lubricants are used that will meet OEM standards.

Do you need to break-in engine after rebuild?
From 500 to 1,000 miles, drive normally but keep rpm below 5,000. Always avoid long periods of idling during this time, says Summit. It’s all a pain in the you-know-what. But it’s only 1,000-1,500 miles, and if you want to go 100,000 or 150,000 miles on your rebuilt or built-up motor, it’s a small price to pay.
How long will a rebuilt engine last?
Most engines can last up to 300,000 miles if all repairs and maintenance are done according to the manufacturer’s recommendations and are not abused in any way. If you are a good driver who observes all the rules and takes care of your vehicle the way it should, then your rebuilt engine can last for a very long time.
What happens if you don’t break-in your engine?
If there are imperfections in the pistons or the cylinder walls from the manufacturing process, working the engine too hard and too soon can wear down those imperfections too quickly. That leads to “hot spots” within the engine’s cylinders, which can cause problems in the years to come.
How long is engine break-in period?
However, the typical break-in period is within the first 500-1000 miles. If you give in to the common urge and start pushing your engine too hard early on, you risk accelerating this process, causing minute imperfections in the size and shape of engine components.
For petrol engined cars, the manufacturers usually ask you keep the revs limited to 2,500-2,700 rpm and try and not go beyond 80kmph, at least for the first 1,000-1,200km. After you have crossed the 1,200km mark on the odometer, then you can rev upto 3,000-3,200rpm and maybe touch 100-110 kmph.
Do new engines need running in?
A: Most new cars don’t require running-in, but you certainly won’t do your engine any harm by taking it easy for the first few hundred miles. It’s worth checking your car’s handbook to see if there’s a specific running-in procedure, though.
Is it OK to drive a new car long distance?
It is a bad idea to drive a new car on a long distance trip because the gears and engine might not be adequately lubricated and could wear out faster. Therefore, it’s best to take shorter drives in a new car before going on long distance trips.
How many miles does it take to break-in a new truck?
Many major truck brands recommend that you don’t drive faster than 70mph during your first 500 miles. While this is just a guideline, make sure you read the manual for yourself to get an accurate number. For example, the new Ford F-150 guide recommends breaking in the engine for the first 1,000 miles.
Is it OK to tow with a brand new truck?
You shouldn’t use your truck to pull a trailer until it has at least 500 miles under its belt. Check your manual, because some truck manufacturers don’t recommend towing with it until at least 1,000 miles.
Oil consumption can be high for the first 6,000 miles or so but should slow, particularly if you treat the car gently to start with. Brand new tyres have a thin oily coating (mould release agent from when the tyre was made) – this can affect handling but it wears off within 3-5 miles.
What is the best oil for engine break-in?
Instead, look for an engine oil marketed specifically as engine break-in oil. Better yet, look to the performance industry leader, VP Racing Fuels, to give you the maximum out of your freshly built engine. VP’s SAE 10W-40 Break-In oil has a balanced level of ZDDP and moly anti-wear additives.
What causes a piston to break-in an engine?
During engine operation, pistons can break as a result of a forced fracture or can suffer a fatigue fracture. A forced fracture (Fig. 1) is always caused by a foreign body that collides with the piston while the engine is running. These foreign bodies could be parts of the connecting rod, crankshaft or valves, etc.
Can I use diesel oil as break in oil?
Some engine builders like to use API CJ-4 diesel motor oil as a break-in lubricant for new engines. That’s because it contains plenty of zinc (ZDDP) to protect flat-tappet camshafts.
What is the type of oil used for a newly rebuilt engine?
When breaking in any new or rebuilt engine, we recommend a dedicated Break-In Engine Oil. These are all conventional (mineral-based) oils with higher levels of ZDDP.
Is it normal for a rebuilt engine to burn oil?
Engines that have been completely overhauled and rebuilt will burn some oil for the first couple of thousand miles. It is in these first couple of thousand miles that the engine does a lot of breaking in. After an engine overhaul, it is a good idea to change the oil after 500 miles and again after 1000 miles.
