The details are as follows: 1. Vaseline: Many car enthusiasts and even automotive reviewers recommend using white Vaseline to maintain door seals (but it should not be used on sunroof seals), claiming it is the simplest and most effective maintenance method. However, there are concerns that Vaseline can dissolve rubber—for example, condoms strictly prohibit the use of Vaseline as a lubricant. In the short term, Vaseline may soften the seals, but over time, it can cause them to harden and shorten their lifespan. 2. Dimethyl silicone oil (silicone): Dimethyl silicone oil is an excellent rubber conditioner, commonly used for professional medical equipment, slingshots, and high-pressure air pumps.

Why does the new spark plug cause idle vibration?

Idle vibration after replacing a new spark plug may be caused by damaged or broken cylinder wires during the replacement process, leading to abnormal ignition. Alternatively, it could be due to installing spark plugs of a different model. If the issue is confirmed to be related to the spark plug, simply replacing it with the correct model can resolve the problem. Below are some relevant details: 1. A car operates by relying on the engine, and the smooth running of the engine depends on the continuous sparking of the spark plugs. Spark plugs are wear-and-tear components that naturally degrade over time, requiring replacement. 2. As a consumable part, spark plugs experience gradual wear on their positive and negative electrodes with prolonged use, leading to an increased ignition gap. However, this change is gradual and affects other related parameters as they adjust accordingly. Therefore, when a vehicle's spark plugs are significantly worn, the ignition gap also increases. For example, if the original gap was 0.8 and it increases to 1.1 before replacement, the excessive difference and rapid change can cause engine damage if not properly recalibrated.
