Will using 0w20 engine oil cause cylinder scoring in the Sylphy?
2 Answers
Using 0w20 engine oil in the Sylphy will not cause cylinder scoring. Cylinder scoring is one of the common failures in car engines, referring to deep grooves being formed on the inner walls of the cylinders, resulting in the loss of sealing between the piston, piston rings, and cylinder walls. This leads to a reduction in cylinder compression pressure and loss of power. The Sylphy shares its lineage with the Bluebird, first introduced in 1959. Its dimensions are 4641mm in length, 1815mm in width, and 1450mm in height, with a wheelbase of 2712mm. The Sylphy is equipped with an all-aluminum inline four-cylinder engine, paired with either an XTRONIC CVT intelligent continuously variable transmission or a 5MT manual transmission. The front suspension features a MacPherson strut with a high-rigidity stabilizer bar, while the rear suspension is a high-rigidity torsion beam setup.
I previously drove a 2014 Sylphy and always used 0W20 oil. After running 150,000 km, the engine was still exceptionally smooth. This low-viscosity oil has excellent fluidity, and the Sylphy's engine was designed with this type of oil in mind, so there's absolutely no risk of cylinder scoring. However, you must be extra careful not to buy counterfeit oil—I once got fake oil from a small roadside shop, and the engine noise noticeably increased. Also, stick to the 5,000 km maintenance schedule. There was a time when I was on a business trip and delayed the oil change by 2,000 km, and the oil had turned as black as soy sauce. Remember to use reputable brands of 0W20 from official channels, ideally paired with the original factory oil filter. Maintain it this way, and the car will practically never break down.
