DOT fluid is classified into four categories: DOT 3, DOT 4, DOT 5, and DOT 5.1. DOT 3 and DOT 4 fluids are the most common and are compatible with most vehicles. DOT 3 fluid has a lower boiling point than DOT 4, making it less expensive but also less effective in high-performance vehicles. DOT 4 fluid is suggested for high-performance vehicles. DOT 5 fluid is silicone-based and is incompatible with vehicles that use DOT 3, DOT 4, or DOT 5.1 fluids. It is commonly used in military and industrial applications. DOT 5.1 fluid is a high-performance fluid that is similar to DOT 4 but has a higher boiling point. It is important to use the correct type of fluid for your vehicle, as using the wrong type can cause damage to the ... read more
