How to properly clean a Petrol Car engine

For new or newly replaced Petrol Car engines, since the mileage is short and the vehicle is in good condition, you only need to do the following: Choose Petrol Car engine oil with the right quality and viscosity level; It is best to change the oil immediately after driving a certain distance. If this is not possible, you should also start the vehicle for a few minutes before changing the oil to allow the lubricating oil to circulate evenly inside the Petrol Car engine, so that various sediments can be taken out together;

Open the drain port at the bottom of the Hongqi Car engine and put all the oil into the prepared container (the oil is hot, be careful of burns). After completion, do not close the drain port immediately, and When the engine is idle for a while, ensure that the residual oil in the Petrol Car engine is completely discharged; observe the state of the discharged oil. If there is a bad smell, it is very viscous or there is a stratification phenomenon, the oil change cycle should be shortened. If there is a strong smell of fuel, it means that the combustion chamber of the Petrol Car engine is not well sealed, and it is recommended to repair it;
Close the drain bolt, replace the Hongqi Car engine oil filter, wipe the dust around the oil filling port on the top of the Petrol Car engine, open the oil filling port, add fresh oil to the upper limit of the oil dipstick, close the oil filling port, start the Petrol Car engine, idle for a few minutes, and stop; check the dipstick, add oil appropriately to the upper limit of the dipstick, close the oil filling port, and end the oil change.
The Petrol Car engine cleaner mentioned just now can also be said to be a means of Petrol Car engine maintenance. It has a certain effect on new cars and cars with little dirt, but it must be used correctly. According to the survey, the best-selling products of lubrication system maintenance products in 4s stores are Petrol Car engine cleaners and Petrol Car engine protectors. However, if the repairman asks you to use up the Petrol Car engine cleaner and asks you to add a bottle of protector to the new engine oil, you should refuse.
It is not very effective for old cars and cars with a lot of stains, and it will cause damage to the car, because the stains that have already settled will be acidified and circulated again, causing the fuel pipe to be blocked and the lubrication to be poor, and even burning the tiles. For oil friends who like to change oil frequently and like to have a high quality, you don't need to use Petrol Car engine cleaner. It is only suitable for those car owners who use SL and below oil and do not maintain them on time.
