{{Short description|Certification for two-stroke oils}}

API-TC is a certificate for two-stroke oils. It is given by the American Petroleum Institute. The certification is given after passing tests that determine the level of detergent performance, of dispersion, and of anti oxydation. The highest level of certification for 2 stroke oil is the TC.

'''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 [[JASO 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.<ref>{{Cite web|title=ISO Two-Cycle Oil Specifications - oilspecifications.org|url=https://www.oilspecifications.org/iso_2t.php|access-date=2022-04-14|website=www.oilspecifications.org}}</ref> API-TC has been removed from the API website.

A higher grade, TD, was considered similar to the [[National Marine Manufacturers association]] (NMMA) "TC-W" (water-cooled outboard engine) grade. The NMMA has now replaced this specification with the higher TC-W3 standard.<ref>{{Cite web|title=API Two-Cycle Motor Oil Specifications - oilspecifications.org|url=https://www.oilspecifications.org/api_2t.php|access-date=2022-04-14|website=www.oilspecifications.org}}</ref>
