Engine 2.4 G4KJ. Is it worth buying a Kia Optima with such an engine?

Resource and service. Important design improvements

What viscosity and brand of oil should I fill? Companies involved in repairing Korean cars keep statistics. The results are disappointing – no matter what you buy Motul or Lukoil, the engine will still fail.

In addition, a relatively reliable part (the hydraulic coupling of the intake camshaft phase shifter) was replaced with an electric one. It is changed together with the timing mechanism. Cost of el. couplings is about 30,000 rubles. Spare parts alone to replace a set of chains, couplings and dampers will cost 60,000 rubles. Give up hope of capitalizing on the engine for 100,000 rubles. It can only be well served for the money.

Which engine is better to choose a car with?

When purchasing a Kia Optima, the future car owner is faced with the question of which engine option to choose. We are talking, first of all, about the car currently being produced, that is, the 4th generation. There are three versions available for domestic consumers to choose from – 2-, 2.4-liter and turbo version.

Here the buyer needs to take into account the conditions under which he plans to operate his future car, how much money he is willing to pay, including tax fees per liter. pp., how much he plans to spend on fuel refueling and consumables.

For example, a turbocharged modification is suitable for those who are accustomed to sporty driving, as well as those who plan to subject the engine to further improvements, bringing the unit to record dynamics in its segment – acceleration to 100 km/h in 5 seconds.

Otherwise, if the driver is not used to it or he simply has nowhere to learn dynamic driving, the first two versions are suitable. At the same time, the 2-liter option is the most economical and has sufficient power for moving around the city. For those who are going on long trips or business trips, a more powerful and larger 2.4-liter engine is better suited.

If we talk about engines of earlier versions, then everything is decided by the preferences of the car owner himself. Diesel units have always been considered the most economical. However, their level of environmental friendliness is always lower than that of gasoline ones. This is especially true for those who are planning to travel along European roads. In addition, the operating parameters of a diesel engine are significantly affected by the level and quality of fuel, which in Russian conditions is not always the best.
