Reasons for Deformation of Passat Rubber Seals?

1 Answers
VanZoe
07/30/25 3:40am
This is a normal occurrence, as exposure to wind, sun, and rain can cause rubber seals to deform and age. If it does not affect usage, it can be left as is. Functions of Rubber Seals: Rubber seals are primarily used to prevent external liquids and gases from entering the vehicle, blocking and reducing noise. Additionally, they provide some vibration and dust resistance, as well as decorative effects, enhancing driving comfort and protecting vehicle components. Solutions: To delay the aging of rubber seals, applying some petroleum jelly can effectively protect them. If usage is affected, replacing the rubber seals is the only permanent solution.

The Difference Between Semi-Synthetic and Full Synthetic Engine Oil

Full synthetic engine oil is more expensive than semi-synthetic engine oil. The differences between full synthetic and semi-synthetic engine oils are as follows: Difference 1: Different base oils. Semi-synthetic engine oil uses Group III base oil; full synthetic engine oil is a blend of Group III, IV, and V base oils. The replacement intervals differ—semi-synthetic engine oil should be replaced every six months or 7,500 kilometers, while full synthetic engine oil can last one year or 10,000 kilometers. Difference 2: Operating temperature range. Full synthetic oil has a wider temperature range. Under the same conditions, it can protect the engine with lower viscosity, whereas semi-synthetic oil has higher requirements. Applicability also varies—semi-synthetic oil is more suitable for economical small-displacement engines with smooth driving, while full synthetic oil performs well under harsh conditions, offering better high-temperature resistance and low-temperature performance. Difference 3: Different additives. Full synthetic oil contains higher TBN (Total Base Number) additives, extending oil life and improving engine cleanliness. Semi-synthetic oil has lower TBN content, shortening the maintenance interval and potentially producing sulfated ash. Due to premium base oils and superior additives, full synthetic oil exhibits less volatility, greater stability, reduced friction, and viscosity that remains stable across temperature changes. Difference 4: Price difference. Full synthetic oil involves more advanced refining and additive technologies, resulting in higher production costs. Thus, it is priced higher than semi-synthetic oil. Performance-wise, full synthetic oil outperforms semi-synthetic oil, providing better engine protection and internal cleaning.

What is the optimal time to replace car tires?

Car tires should be replaced every 3-5 years for optimal performance. Tire maintenance: Store tires safely in a cool, dry, and dark indoor environment, avoiding exposure to sunlight, oil, acid, or hydrocarbons. Due to pressurization, liquids may penetrate the tire's inner liner into the carcass layer, potentially causing sudden tire damage. Tire care includes regular rotation, selecting appropriate tread patterns, routine maintenance, periodic pressure checks, prompt repair of damages, and frequent removal of stones or foreign objects from tread grooves. Maintain good driving habits such as smooth acceleration, moderate speed driving, and avoiding emergency braking.
