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 \u2014 a major contributor to heat, wear, and premature aging of engine parts. STP\u00ae\u00a0Oil Treatment fights this metal-to-metal friction by providing a thick cushion of oil between moving engine parts, thus helping to protect against engine wear.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

STP\u00ae\u00a0Oil Treatment can be added at any time. For maximum results, it\u2019s best when added to fresh oil in a warm engine right after an oil change.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Where does sludge come from? <\/h3><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

Sludge is a thick, sticky residue that can form inside your engine through a combination of combustion by-products (oil oxidation residue, carbon and water). Water condenses as a result of a hot engine cooling down. The oil mixes with the resulting water and forms a thick sludge that sticks to the engine parts. Frequent cold starts and short trips contribute to this condition by not allowing the engine oil to heat up enough to vaporize and remove the water. Sludge is detrimental in that it can clog key oil passages such as oil drain-back holes and, in some cases, block the oil pickup screen in the oil pan, causing engine oil starvation (i.e., not enough oil). STP\u00ae Oil Additive products contain detergents, which can help suspend sludge in the motor oil and prevent it from accumulating inside your engine.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

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.
