How to Solve the Oil Burning Issue in BYD F3?

[McJuliette]

If the vehicle experiences minor oil burning, using higher quality engine oil can effectively alleviate the problem. For older vehicles, it is advisable to use engine oil with slightly higher viscosity. If the issue persists, the only solution is to dismantle and repair the engine, which requires a major overhaul.

As a long-time owner of a BYD F3 for over a decade, I've found oil burning to be a fairly common issue. Initially, the engine oil consumption suddenly increased, and blue smoke emerged from the exhaust pipe, indicating worn piston rings or faulty valve guide seals, allowing oil to seep into the combustion chamber and burn. If not addressed promptly, the engine may overheat or even be completely ruined. Solutions include first trying a specialized oil additive designed for oil burning, which can temporarily fill in the worn areas; if that doesn't work, a trip to the repair shop for disassembly and replacement of piston rings or valve components is necessary. For prevention, I use high-viscosity oil and regularly check the oil level every 5,000 kilometers, along with cleaning the oil-gas separator, which helps extend the engine's lifespan.

My car is a 2015 BYD F3. When it was burning oil, it seriously affected driving safety—severe idle vibration and rapid oil level drop. I tried adding additives myself to alleviate the issue for two months, but eventually found the piston rings were severely aged. Now during every maintenance, I emphasize having the mechanic thoroughly inspect the engine internals to prevent delays. I suggest you immediately visit a professional repair shop for diagnosis—don't gamble with luck. Although replacing parts may cost a few thousand, it avoids more expensive engine overhauls and potential breakdown risks.

If the BYD F3 is burning engine oil, I start with simple checks. First, see if the oil dipstick level drops rapidly, then observe whether there is blue smoke from the exhaust pipe. At the same time, try switching to a high-quality engine oil, such as a slightly higher viscosity grade. The cause is mostly due to worn piston rings or seals, and not addressing it will accelerate wear. I've tried additives for short-term improvement, but in severe cases, it's still necessary to seek repairs.
