Alifbeetada saliidda
Maahmaahda " who lubricates the gears" waa furaha marka laga hadlayo saliidaha gawaarida.
Joogitaanka cutubka korantadu waxay ku xiran tahay kaliya tayada saliidda, laakiin sidoo kale xulashada saxda ah ee mishiinka gaarka ah. Matoorka casriga ah ee xoogga badan iyo matoorka gebi ahaanba ka duwan oo muujinaya calaamado la taaban karo ayaa u baahan saliid kale.
Hawsha ugu weyn ee saliiddu waa in ay saliidayn oo ka hortagto xidhiidhka tooska ah ee u dhexeeya laba walxood oo is-dhexgalka. Jebi lakabka saliidda, i.e. jebi waxa loogu yeero. Filimka saliidda ayaa keenaya xirmo aad u degdeg badan oo matoorka ah. Saliideynta ka sokow, saliidda sidoo kale way qaboojisaa, yareysaa buuqa, waxay ka ilaalisaa daxalka, xirto oo ka saartaa wasakhda. 
Sida loo akhriyo saliidda
Dhammaan saliidaha baabuurta waxaa loo qaybin karaa saddex kooxood oo waaweyn: macdanta, semi-synthetic iyo synthetic. Saliid kastaa waxay qeexdaa dhawr qaybood oo aasaasi ah, sida darajada iyo viscosity. Heerka tayada (sida badan API) wuxuu ka kooban yahay laba xaraf (tusaale SH, CE). Midka kowaad wuxuu qeexayaa injiinka saliidda loogu talagalay (S for basiin, C ee naaftada), iyo tan labaad waxay qeexaysaa heerka tayada. Markasta oo xarafka xarafka sare uu sareeyo tayada saliidda (saliid SJ way ka fiican tahay SE, CD-guna wuu ka fiican yahay CC). Marka lagu calaamadiyo SJ/CF, waxaa loo isticmaali karaa labadaba shidaalka iyo matoorada naaftada. Halbeegga labaad ee aadka muhiimka u ah waa kala-soocidda viscosity (inta badan SAE), taasoo go'aamisa kala duwanaanta heerkulka lagu isticmaali karo. Waqtigan xaadirka ah, ku dhawaad kaliya saliidaha multigrade ayaa la soo saaraa, sidaas darteed calaamaduhu waxay ka kooban yihiin laba qaybood (tusaale ahaan, 10W-40). Midka ugu horreeya ee xarafka W (0W, 5W, 10W) wuxuu muujinayaa in saliidda loogu talagalay isticmaalka jiilaalka. Lambarka hoose, ayaa si fiican saliidda u qabata heerkulka hooseeya. Qaybta labaad (30, 40, 50) waxay ku wargelinaysaa in saliidda la isticmaali karo xagaaga. Mar kasta oo uu sarreeyo, waa ka adkeysi badan u leh heerkulka sare. Viscosity khaldan (saliid aad u dhumuc weyn ama dhuuban), matoorku si dhakhso ah ayuu u fashilmi karaa. Saliida macdantu waxay inta badan leeyihiin muuqalka 15W-40, semi-synthetic 10W-40, iyo saliidaha synthetic 0W-30, 0W-40, 5W-40, 5W-50.
Shuruudaha Xulashada
Markaad dooranayso saliid, waa inaad marka hore tixgelisaa cabbirkeeda, oo maaha calaamadda, oo lagu hagayo talooyinka soo saaraha baabuurta (tusaale, VW, heerarka 505.00, 506.00). Waxaad isticmaali kartaa saliidda ugu waxtarka badan, laakiin ma aha tan ugu xun. Waxa kale oo jira saliidaha matoorada ku shaqeeya gaaska dareeraha ah, laakiin looma baahna in la isticmaalo, waa ku filan in la ilaaliyo muddada isbeddelka saliidda ee la isticmaalo ilaa hadda.
Saliida synthetic waxay u fiican tahay matoorada cusub iyo kuwa la isticmaalo sababtoo ah waxay bixiyaan ilaalin wanaagsan oo matoorka ah, way sii dheeraanayaan waxayna aad ugu adkeysanayaan xaaladaha adag ee shaqada. Saliidahani waxay leeyihiin heerkul aad u ballaaran, sidaas darteed matoorka si habboon ayaa loo subkay qabow iyo kulayl aad u daran. Matoorada kuleylku ku raran yahay, sida matoorada shidaalka turbocharged, waxaa loo isticmaali karaa saliido leh aragti 10W-60 ah, kuwaas oo aad u adkeysanaya heerkulka sare.
Haddii matoorku leeyahay masaafada sare oo uu bilaabo inuu "qaado" saliid, ka beddel synthetics una beddel semi-synthetics. Haddii tani aysan ku caawin, waxaad u baahan tahay inaad doorato macdanta. Matoorada aadka loo xidho, waxa jira saliido macdaneed oo gaar ah (tusaale Shell Mileage 15W-50, Castrol GTX Mileage 15W-40) kuwaas oo xidha mishiinka, yareeya isticmaalka mishiinka oo yareeya buuqa.
Markaad isticmaasho saliidda macdanta ee aan tayadoodu aad u wanaagsanayn, ku shubista saliidda synthetic ee mashiinka noocan oo kale ah, kaas oo leh sifooyin nadiif ah oo aad u wanaagsan, waxay u horseedi doontaa niyad-jabka mashiinka iyo dhaqida kaydka. Waxayna tani keeni kartaa in ay xidhmaan kanaalada saliidda iyo saxmada mishiinka. Haddii aynaan garanaynin waxa saliidda lagu shubay, oo matoorku aanu lahayn masaafada sare, way ka badbaado badan tahay in lagu shubo semi-synthetics, kuwaas oo aan qaadin khatar la mid ah tan synthetics, iyo ilaalinta mishiinka si aad uga fiican saliidda macdanta. Dhanka kale, way ka badbaadsan tahay in matoorka masaafada sare lagu buuxiyo saliid macdaneed wanaagsan. 
tayo leh. Xaaladdan oo kale, khatarta ah in la dhaqo wasakhda iyo furitaanka waa yar tahay. Ma jiro xad gaar ah oo masaafada aad ka bedeli karto synthetics una beddesho biyaha macdanta. Waxay kuxirantahay kaliya xaalada matoorka.
Waxaan hubineynaa heerka
Heerka saliidda waa in la hubiyaa 1000 kiiloomitir kasta, waxaana la doorbidaa mar kasta oo aad buuxiso ama ka hor intaadan sii wadin safarkaaga. Marka ay lagama maarmaan noqoto in lagu daro saliid, laakiin ma iibsan karno isku mid ah, waxaad isticmaali kartaa saliid kale, oo doorbidaya tayada tayada iyo heerka viscosity. Haddii tani aysan ahayn kiiska, ku shub saliid leh xuduudaha ugu dhow ee suurtogalka ah.
Goorma ayaa la bedelayaa?
Si matoorku u helo nolol dheer oo adeeg ah, kuma filna in la isticmaalo saliidda saxda ah, waa in sidoo kale loo beddelaa si nidaamsan, iyada oo la raacayo talooyinka soo-saaraha. Baabuurta qaar (sida Mercedes, BMW) isbeddelka waxaa go'aamiya kombuyuutarka iyadoo ku xiran xaaladda saliidda. Tani waa xalka ugu fiican, sababtoo ah beddelaadku wuxuu dhacaa kaliya marka saliidda dhabta ah ay lumiso xuduudaha.
