Line 1:

'''API TC''' is a [[product certification|certification]] for [[Two-stroke cycle|two-stroke]] [[Motor oil|oils]], awarded by the [[American Petroleum Institute]]. It is given after the product passes through stringent tests that determine the level of [[detergent]] performance, [[Dispersion (chemistry)|dispersion]], and [[Antioxidant|anti-oxidation]]. It is the only remaining, not revoked classification of the API Two-Cycle motor oil specifications (TA, TB, TC, TD). Being a very old standard itself, most currently produced 2T lubricants meet its specifications, even the lowest quality ones; current high-quality oils exceed them (often labeled "API TC+" although not based on actual measurements).

The more current [[JASOJASO_M345]] or the international [[ISO]] two-cycle oil specifications are much better indicators of oil quality, with requirements based on modern two-stroke engines and environmental policies.
