Litlolo li akaretsa libaka tse fapaneng, 'me litlhoko tsa naha ka 'ngoe lia fapana. Ho rona, ho na le lik'hamphani tse 7 tse fetisitseng tekanyetso ea API, 'me le lik'hamphani tse fokolang tse fetisitseng tekanyetso ea teko ea oli ea moetsi oa likoloi. Linaha le lik'hamphani lefatšeng ka bophara li theha litlhaloso tsa oli ea likoloi haholo-holo ho netefatsa hore lihlahisoa tsa oli tse hlahisoang ke bahlahisi ba litlolo li ka netefatsa litlhoko tsa ts'ebeliso ea likoloi. Ka hona, ha bareki ba reka litlolo, ba tlameha ho hlahloba hore na moetsi o netefalitsoe ke mekhatlo e nang le tumello e boletsoeng ka holimo. Mafapha a nang le tumello e kholo ea ho khetholla litlolo machabeng a kenyelletsa API (American Petroleum Institute), ACEA (European Automobile Manufacturers Association), ILSAC (International Lubricant Standards and Certificate Committee), le JASO (Japane Automotive Standards Organization, e entsoeng ka lekala la Japane la SAE (American Society of Automotive Engineers)).
1. Oli ea enjene ea ho chesa ka hare (LE) ka kakaretso e na le letšoao la API. E rekisoa haholo-holo United States. Ho ea ka maemo a oli ea likoloi a API, e ka aroloa ka mekhahlelo e 'meli:
E 'ngoe ke oli ea khoebo (Oli ea Khoebo), joalo ka oli e sebelisoang literaka tse mahareng le tse kholo, libese, likoloi tsa boenjiniere, jj. Bongata ba likoloi tsena li sebelisa disele e le mafura, a emeloang ke tlhaku ea C. Mohlala: CA, CB, CC, CD, CE, CF, CG, CH, CI.
Ea bobeli ke oli ea enjene e rekisoang liteisheneng tsa peterole tse akaretsang (Litsing tsa Tšebeletso), tseo hangata li sebelisoang likoloing le likoloing tse nyane tse nang le lienjene tsa peterole (ntle le lithuthuthu tse nang le li-stroke tse peli), tse emeloang ke tlhaku S. Mohlala: SA, SB, SC, SD, SE, SF, SG, SH, SI, SJ, SL, SM, SN. (Hlokomela: S e emetse Oli ea Enjene ea Peterole, 'me C e emetse oli ea enjene ea diesel. Tlhaku ea bobeli ea Senyesemane e emela sehlopha, 'me ha sehlopha se le holimo, sehlopha se phahame. Mohlala, SB e phahame ho feta SA, 'me SC e phahame ho feta SB.)
2. Oli ea ho tlotsa e sebelisoang ho tlotsa lisebelisoa tsa phetisetso ea li-gear ho kenyeletsoa le lipara tsa li-gear tsa liboko e bitsoa Oli ea Lisebelisoa (LC). Ho ya ka GB 7631.7-89, oli ya gear e arotsoe ka oli ya gear e kwetsweng ya indasteri, oli ya gear e bulehileng ya indasteri, le oli ya gear ya koloi.
3. Sesebelisoa sa ho sebetsa se sebediswang tsamaisong ya kgatello e sa fetoheng ya mokelikeli (phetiso ya hydraulic) se bitswa oli ya hydraulic, ha sesebelisoa sa ho sebetsa se sebediswang tsamaisong ya kgatello e matla ya mokelikeli (phetiso ya hydraulic) se bitswa Oli ea Phetiso ea Haeteroliki. Tse peli hangata li bitsoa oli ea hydraulic (LH) ka kakaretso. Ha li bapisoa le oli ea enjene, oli ea hydraulic e na le anti-emulsification e ntle, anti-wear, hydrolysis e tsitsitseng, filterability, anti-foaming le air release properties ho phaella ho thepa ea motheo ea oli ea enjene.
