Haval 1.5T requires approximately 4.3 liters of engine oil. Add the normal amount of engine oil: When performing yourself, be careful not to add too much or too little oil. Usually, imported GT engine oil is added. For the Haval 1.5T engine, adding 5L leaves more than half a bottle remaining. If you want to check the lubricant level, the car must be parked on a flat surface, and the engine should be stopped for at least 10 minutes before checking. Then, pull out the oil dipstick to inspect. Precautions for adding engine oil: When selecting engine oil, strictly follow the oil grade specified in the car's manual. If oil of the same level is not available, you can use oil of a higher level, but never use oil of a lower level as a substitute.

My Haval H6 has a 1.5T engine, and it takes about 4.7 liters of oil for each oil change, which just reaches the middle mark on the dipstick. Last time at the 4S shop, the mechanic mentioned that the oil pan design of the new engine has changed, while the older models might only require 4.3 liters. Remember to add the oil in two steps: first pour in 4 liters, start the engine and let it run for two minutes, then turn it off and check the dipstick before adding the remaining amount. The most suitable oil type is 5W-30 full synthetic, especially for better cold start protection in northern winters. Be careful not to overfill, as excessive crankshaft case pressure can damage the seals—my neighbor had to spend over 3,000 yuan on repairs because of this issue.

The manual clearly states that the Haval 1.5T requires 4.5±0.2 liters of engine oil, a quantity thoroughly tested by engineers. Once when I changed the oil myself, I used a mineral water bottle as a measuring cup, and 4.5 bottles filled it right up to the upper mark on the dipstick. A reminder: there are differences between model years. For example, post-2020 models equipped with the GW4B15 engine consume 0.2 liters more than older versions. Additionally, it's recommended to use full synthetic oils like Shell Helix or Mobil, as turbocharged engines run at higher temperatures and regular mineral oils can't withstand the heat.

The actual refill amount may vary. Yesterday, I helped my colleague change the oil in their Haval F7. After completely draining the old oil, it took 4.6 liters of Total engine oil to reach the midpoint on the dipstick. The workshop mechanic emphasized three key points: the vehicle must be on level ground and shut off for five minutes before checking the level; in winter, you should add 50ml more than in summer; and when replacing the oil filter, an additional 0.1 liters of oil is required. If abnormal oil consumption is noticed, the turbocharger seals should be inspected—a friend's car had this issue, requiring a 0.5-liter top-up every three months.

From a practical standpoint, 4.5 liters serves as a reference benchmark. Once during an oil change, an apprentice initially poured in 5 liters, resulting in oil spraying all over the air filter box. It wasn't until half a liter was extracted that the level normalized. Now, I always instruct mechanics to use professional measuring cups for precise quantity control. As a side note, for models prone to oil burning, it's advisable to keep half a liter in the trunk, especially during long-distance trips. Last year during my self-drive trip to Tibet, I encountered an oil warning at 4,000 meters above sea level—fortunately, I had brought spare oil.

It is recommended to use the dipstick markings as a reference. Last week when I changed the oil myself, after pouring in 4 liters and starting the engine for circulation, I noticed it was still below the minimum line, so I added another 0.6 liters. Remember to use a graduated oil can – I almost spilled everywhere when measuring with a soda bottle. Adjust appropriately for different seasons; in summer, you can add 50ml less to avoid excessive pressure. Additionally, after changing the oil, drive 100 kilometers before rechecking, as the new oil filter will absorb some oil.
