Oil Leak Repair Cost and How Do We Prevent It

Oil/fluid leaks are considered to be the most typical problem that vehicle owners typically deal with. If you check for stains, puddles or blemishes under your vehicle, don't ignore it and ask your local mechanic to check and fix the problem as soon as possible. If the engine is leaking oil, you need to address the problem immediately as it will oil the engine components.
Hydraulic Seals and Oil Seals and Their Use

Hydraulic seals are typically made from elastomers, natural and synthetic polymers that have weak molecular attraction and high elastic properties. The two primary sources of hydraulic seals are rubber and plastics (including PTFE, such as Teflon and polyurethane). Other elastomeric materials used to make seals include butadiene, nitrile, butyl and silicone resins.
