Frequently Asked Questions
Motor oils are carefully formulated lubricants that perform many important functions, including cooling engine parts, keeping them clean, and protecting them against rust, corrosion, and wear. One of the most important functions of oil is providing lubrication by forming a cushion between moving parts to help them slide more easily. This reduces metal-to-metal contact and friction — a major contributor to heat, wear, and premature aging of engine parts. STP® Oil Treatment fights this metal-to-metal friction by providing a thicker cushion of oil between moving engine parts, thus helping to protect against engine wear.
Many car manufacturers state that after-market oil additives are not necessary, even though they sell their own brand of oil additives. Some after-market oil additives contain corrosive chemicals, including chlorine-based lubricating compounds that may be harmful to internal engine parts. STP® products do not contain any corrosive components and are safe for use in all engines.
