Shell Helix HX5 10W40 oil is not semi-synthetic oil. Methods for choosing suitable motor oil for vehicles: Selecting the appropriate viscosity: When choosing motor oil, it's best to use multi-viscosity lubricants. Multi-grade lubricants (also called multi-weight oils) exhibit properties of light oil at low temperatures and heavy oil at high temperatures. In applications where multi-grade oils are recommended, one multi-grade oil can replace multiple single-grade oils. Choosing oil according to seasons: Although multi-grade oils can meet the needs of extremely cold and warm seasons as well as heavy-duty engines - especially for diesel engines that don't have cold-start difficulties - single-viscosity lubricants are usually recommended as they benefit engine lubrication and extend engine lifespan.

Can Lubricating Oil Be Added to Car Keyholes?

It is advised not to add lubricating oil to the keyhole. Below are relevant details: Lubricating Grease: Since the lock cylinder requires a certain amount of lubricating grease during the manufacturing process, it is important to keep the key surface clean to prevent dust from being carried into the lock cylinder, especially for new car owners. Preventing Foreign Objects: When using the key to unlock, check for any foreign objects inside or around the lock cylinder hole to avoid damage. Door Locks: Regularly inspect vehicle door locks every 6 to 12 months based on usage frequency and wear. Since door locks are not sealed, they are significantly affected by external environments; sand erosion and temperature changes can degrade the performance of the lubricating grease, impacting the lock's functionality.
