a really good 6 cylinder and a really good 4 cylinder which engine will get greater kilometers?

Question

meaning which will last longer

Answer 1

In the same car, the larger, more powerful 6-cylinder engine will probably last longer, as it doesn't have to work as hard to keep the car moving down the road.

Answer 2

In theory, the larger engine should last longer but it depends on how hard you drive it. You might drive a 4-cyl more gently than a V-6. An inline 6-cyl will generally outlast a V-6 due to the way the whole cooling process works.

V-6's and inline 4-cyl seem to be more prone to head warpage and head gasket problems but only if the engine is in a car that is too heavy. (HP to curb weight balance is way off.)

I like to think of it like this; one cylinder per wheel and two cylinders to drive the accessories, minimum. Cars with A/C that is run a lot will put more strain on a motor. The A/C compressor engages in Winter when you use the defroster, too.

Many factors to consider but a well maintained engine that is not constantly pushed to the edge of its performance ability will last a very long time. Servicing the cooling system is as important as servicing the oil and letting things go until you hit 100,000 miles or 160,000 kilometers is no way to maintain a car but this is what the owners manuals will have you believe in some newer models. They still may be running but certainly not as well as "like new".

Good Luck!

Answer 3

The 6 will generally outlast the 4. 6 cylinder engines are usually larger displacement (CC's, liters, or cubic inches), and operate at lower revolutions per minute than 4s because they produce more power in every revolution. Therefore every part in the engine is moving and wearing out more slowly. However if they are of comparable displacement, this may not apply.

Answer 4

I would say It's up to you and how well you maintain the engine. Alot of variables come into play as well. Such as what kind of vehicle it is in. Power to weight ratio will be important, is it a diesel? Is it a turbo ? Is it carbureted or FI, but most how well it is maintained. But I would put the smart money on the six, more power for the weight, (less work) but your fuel mileage will suffer.
