Re: Castrol vs. Mobil 1
 

este f bun motul.
la mine, aceeasi cifra , adica 10w40 a insemnat pe ceas 1 bar in plus fata de castrol.
daca ai nevoie de motul iti pot face rost.

Re: Castrol vs. Mobil 1
 

asa mare diferenta? suna bine! motul 10w40 snt mai multe, sau e o singura varianta de 10w40?

Re: Castrol vs. Mobil 1
 

Cam greu de gasit Motul la magazine . In curse la nivel mondial o sa gasesti stickere Motul pe diferite masini si motociclete si nu degeaba. Inca nu am avut Motul dar cu siguranta va inlocui castrolul pe care-l am.

Re: Castrol vs. Mobil 1
 

300V
SINERGIE 6100+
TURBOLIGHT
MULTIDIESEL

Re: Castrol vs. Mobil 1
 

10w40 la motul inseamna tot semisintetic, ca la oricare alt ulei, nu?

un 5w40 fullsintetic pt diesel, la bidon de 4,5,6l sau care este cel mai mare bidon, inafara de butoi si la ce pret se comercializeaza?

Re: Castrol vs. Mobil 1
 

10x nemilosu pt update. si de care ai folosit tu? cel care a iesit cu un bar in plus la presiune? V-ul?

@vectra: ma impresia ca 300V 10w40 e chiar full sintetic. cauta si tu pe google.

Re: Castrol vs. Mobil 1
 

:) , corect mistreku , bv de observare greselei lui... ps: eu singur folosesc Castrol 10w40 deja de aproape 3 anisori si is multumit si imi place sa schimb vitezele des in 6500rtpm:oops::oops:

Re: Castrol vs. Mobil 1
 

e totusi si o diferenta intre uleiuri, adica e diferenta intre uleiurile diesel fata de cele otto, sau la diesel nu trebuie comparat un motor diesel de prin 94 de mercedes si unu pd de pe golf.

Re: Castrol vs. Mobil 1
 

nu inteleg topicul dar in fine, folosesti ce recomanda producatorul masini nu cred ca e bine sa bagi de capul tau ulei in masina.

Re: Castrol vs. Mobil 1
 

asa e, in sensul ca respecti tipul de ulei, dar nu neaparat si producatorul.

Re: Castrol vs. Mobil 1
 

pai de ex daca bmw recomanda castrol, de ce ar trebui sa pun mobil ?!

Castrol vs. Mobil 1
 

Testele facute personal cu dinamometru au dat castig de cauza lui Mobil1, cu Castrol dinamometru s-a oprit destul de jos, mai jos decit asteptam.Nu folosesc niciunul din cele doua si experientele le-am facut personal din curiozitate.Tot din curiozitate am intrebat un fabricant de aditivi din SUA care a venit la un seminar la noi si care ne-a zis ca Mobil 1 nu e un ulei rau si ca pret comparativ,preturile la noi sunt mult mai mari decit la ei....

Re: Castrol vs. Mobil 1
 

da frate am folosit ce mi-a recomandat VW .. Castrol.. imi consuma 1 litru la 2 luni, am pus mobil 1, consumul a disparut! completez mult mai putin si mult mai tarziu ( 8-9 luni ) ! Am bagat si Elf in ea si iti zic sincer ca tragea extraordinar.

Re: Castrol vs. Mobil 1
 

^
^

cred ca ar trebui sa specifici ce masina ai ...poate ai tu o prob
si eu tot vw am si nu am pus ulei decat la revizie, o singura data intre 2 revizi s-a aprins si am completata cu 200 ml, in rest in 4 ani nu s-a aprins deloc nici un martor deloc !

Re: Castrol vs. Mobil 1
 

golf 5 2.0 tdi cod motor BKD. Ce problema? adica nu inghite uleiu de la castrol si il inghite p'ala de la mobil1? :) mie imi convine..oricum mobil 1 e cu muuuuullt peste castrol.

Re: Castrol vs. Mobil 1
 

mai sincer iti doresc multi km fara nici un incident si sa te bucuri de masina !

eu tot diesel am si merg pe castrol, nu am folosit mobil 1 si nu am de ce sa schimb uleiul mie masina nu imi mananca ulei si sunt lultumit si bag numai 5w-40 vw 505 . 01 - Pumpe Duse, am motor de 1.9

Re: Castrol vs. Mobil 1
 

tot castrol folosesc si eu si nu completez deloc , castrol a fost bagat in masina de cand a fost cumparata !!

p.s Bmw e39 , 2.0d , 2003

Re: Castrol vs. Mobil 1
 

va rog sa specificati si ce bagati ...ex Castrol Edge 5W 40 si masina pe care o aveti

Re: Castrol vs. Mobil 1
 

am facut revizia la 30.000 km, acum am 37.000 si senzorul de la ulei care imi spune calitatea uleiului, mi-a comunicat ca 0w 30, de la mobil 1 trebuie schimbat numai dupa 7.000 km!!!!! este posibil asa ceva?
eu cred ca jegurile alea de la opel service la schimbul de ulei, nu au dat drumul tot la ulei si doar au completat cu ulei nou,asta mi se pare singura explicatie!

Re: Castrol vs. Mobil 1
 

aoleuuu pai l-ai schimbat la opel? am auzit si eu basme ( cred si adevarate ) ca ar fi la fel de prosti ca si porsche.
Mie imi plac service-urile, unde pot sa stau si eu langa masna ca sa vad ca nu isi opresc ei uleiul cumparat si mie imi lasa tot uleiul prost :|

Re: Castrol vs. Mobil 1
 

Pai recomanda Castrol pentru ca au contract cu Castrol si e normal sa-l recomande.

Re: Castrol vs. Mobil 1
 

prietene, ca au contract cu ei OK dar motoarele lor sunt testate cu acest ulei nu cu mobil sau alt ulei.

Re: Castrol vs. Mobil 1
 

Aici asa e. Motul e tata lor. Si eu planuiesc sa imi pun 20w60 la urmatorul schimb.

Re: Castrol vs. Mobil 1
 

Eu nu spun ca, Castrol nu este bun, doar ca exista si mai bun.
Oricum am aflat niste chestii noi referitoare la uleiuri, pe care tehnic nu prea le inteleg dar care mi-au schimbat mult teoriile anterioare.

Re: Castrol vs. Mobil 1
 

nu prea da bine pt mobil fabricarea acestuia in turcia! aud tot mai multe plangeri, asta nu ii face decat sa coboare stacheta, dar se pare ca profitul este mai mare.
asa au facut si cei de la renault si au scazut mult.

Re: Castrol vs. Mobil 1
 

referitor la uleiuri ce inseamna primul numar si al doilea?...de ex:10w40

Re: Castrol vs. Mobil 1

Grades

Range of motor oils on display in KuwaitThe Society of Automotive Engineers (SAE) has established a numerical code system for grading motor oils according to their viscosity characteristics. SAE viscosity gradings include the following, from low to high viscosity: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. The numbers 0, 5, 10, 15 and 25 are suffixed with the letter W, designating their "winter" (not "weight") or cold-start viscosity, at lower temperature. The number 20 comes with or without a W, depending on whether it is being used to denote a cold or hot viscosity grade. The document SAE J300 defines the viscometrics related to these grades.

Kinematic viscosity is graded by measuring the time it takes for a standard amount of oil to flow through a standard orifice, at standard temperatures. The longer it takes, the higher the viscosity and thus higher SAE code.

Note that the SAE has a separate viscosity rating system for gear, axle, and manual transmission oils, SAE J306, which should not be confused with engine oil viscosity. The higher numbers of a gear oil (eg 75W-140) do not mean that it has higher viscosity than an engine oil.

[edit] Single-grade
A single-grade engine oil, as defined by SAE J300, cannot use a polymeric Viscosity Index Improver (also referred to as Vicosity Modifier) additive. SAE J300 has established eleven viscosity grades, of which six are considered Winter-grades and given a W designation. The 11 viscosity grades are 0W, 5W, 10W, 15W, 20W, 25W, 20, 30, 40, 50, and 60. These numbers are often referred to as the 'weight' of a motor oil.

For single winter grade oils, the dynamic viscosity is measured at different cold temperatures, specified in J300 depending on the viscosity grade, in units of mPa·s or the equivalent older non-SI units, centipoise (abbreviated cP), using two different test methods. They are the Cold Cranking Simulator (ASTM D5293) and the Mini-Rotary Viscometer (ASTM D4684). Based on the coldest temperature the oil passes at, that oil is graded as SAE viscosity grade 0W, 5W, 10W, 15W, 20W, or 25W. The lower the viscosity grade, the lower the temperature the oil can pass. For example, if an oil passes at the specifications for 10W and 5W, but fails for 0W, then that oil must be labeled as an SAE 5W. That oil cannot be labeled as either 0W or 10W.

For single non-winter grade oils, the kinematic viscosity is measured at a temperature of 100 °C (212 °F) in units of mm²/s or the equivalent older non-SI units, centistokes (abbreviated cSt). Based on the range of viscosity the oil falls in at that temperature, the oil is graded as SAE viscosity grade 20, 30, 40, 50, or 60. In addition, for SAE grades 20, 30, and 40, a minimum viscosity measured at 150 °C (302 °F) and at a high-shear rate is also required. The higher the viscosity, the higher the SAE viscosity grade is.

For some applications, such as when the temperature ranges in use are not very wide, single-grade motor oil is satisfactory; for example, lawn mower engines, industrial applications, and vintage or classic cars.

[edit] Multi-grade
The temperature range the oil is exposed to in most vehicles can be wide, ranging from cold temperatures in the winter before the vehicle is started up to hot operating temperatures when the vehicle is fully warmed up in hot summer weather. A specific oil will have high viscosity when cold and a lower viscosity at the engine's operating temperature. The difference in viscosities for most single-grade oil is too large between the extremes of temperature. To bring the difference in viscosities closer together, special polymer additives called viscosity index improvers, or VIIs are added to the oil. These additives are used to make the oil a multi-grade motor oil, however it is possible to have a multi-grade oil without the use of VIIs. The idea is to cause the multi-grade oil to have the viscosity of the base grade when cold and the viscosity of the second grade when hot. This enables one type of oil to be generally used all year. In fact, when multi-grades were initially developed, they were frequently described as all-season oil. The viscosity of a multi-grade oil still varies logarithmically with temperature, but the slope representing the change is lessened. This slope representing the change with temperature depends on the nature and amount of the additives to the base oil.

The SAE designation for multi-grade oils includes two viscosity grades; for example, 10W-30 designates a common multi-grade oil. The two numbers used are individually defined by SAE J300 for single-grade oils. Therefore, an oil labeled as 10W-30 must pass the SAE J300 viscosity grade requirement for both 10W and 30, and all limitations placed on the viscosity grades (for example, a 10W-30 oil must fail the J300 requirements at 5W). Also, if an oil does not contain any VIIs, and can pass as a multi-grade, that oil can be labeled with either of the two SAE viscosity grades. For example, a very simple multi-grade oil that can be easily made with modern baseoils without any VII is a 20W-20. This oil can be labeled as 20W-20, 20W, or 20. Note, if any VIIs are used however, then that oil cannot be labeled as a single grade.

The real-world ability of an oil to crank or pump when cold is potentially diminished soon after it is put into service. The motor oil grade and viscosity to be used in a given vehicle is specified by the manufacturer of the vehicle (although some modern European cars now have no viscosity requirement), but can vary from country to country when climatic or fuel efficiency constraints come into play.

OEM standards divergence
By the early 1990s, many of the European original equipment manufacturer (OEM) car manufacturers felt that the direction of the American API oil standards was not compatible with the needs of a motor oil to be used in their motors. As a result many leading European motor manufacturers created and developed their own "OEM" oil standards.

Probably the most well known of these are the VW50*.0* series from Volkswagen Group, and the MB22*.** from Mercedes-Benz. Other European OEM standards are from General Motors, for the Vauxhall, Opel and Saab brands, the Ford "WSS" standards, BMW Special Oils and BMW Longlife standards, Porsche, and the PSA Group of Peugeot and Citroën. General Motors also has the 4718M standard that is used for the Chevrolet Corvette, a standard that is used in North America for selected North American performance engines, with a "Use Mobil 1 only" sticker usually placed on those cars.[citation needed]

In recent times, very highly specialised "extended drain" "longlife" oils have arisen, whereby, taking Volkswagen Group vehicles, a petrol engine can now go up to 2 years or 30,000 km (~18,600 mi), and a diesel engine can go up to 2 years or 50,000 km (~31,000 mi) - before requiring an oil change. Volkswagen (504.00), BMW, GM, Mercedes and PSA all have their own similar longlife oil standards.[citation needed] Another trend of today represent midSAP (sulfated ash <0,8 wt.-%) and lowSAP (sulfated ash <0,5 wt.-%) engine oil (see specifications: Renault RN 0720, FORD WSS-M2C934-A). The ACEA specifications C1 to C4 reflect the midSAP and lowSAP needs of automotive OEMs. Furthermore, virtually all European OEM standards require a long drains of 30.000 km and up by using HTHS (High Temperature, High Shear) viscosity, many around the 3.5 cP (3.5 mPa·s). In Japan, the HTHS figures are low as >2.6 mPas.

Because of the real or perceived need for motor oils with unique qualities, many modern European cars will demand a specific OEM-only oil standard. As a result, they may make no reference at all to API standards, nor SAE viscosity grades. They may also make no primary reference to the ACEA standards, with the exception of being able to use a "lesser" ACEA grade oil for "emergency top-up", though this usually has strict limits, often up to a maximum of ½ a litre of non-OEM oil.

eu am bagat o data cand eram italia ulei bardahl 10w40....am facut cu el aproape 20000 d km.(cel care mi la schimbat mi-a zis ca duce 20000fara probleme)si asa a fost.Eu il recomand.pacat k nu prea se gaseste in romania...........si am fost nevoit sa trec iar la elf.....

Re: Castrol vs. Mobil 1
 

Eu pana acum am avut numai Castrol Edge 10W60 si imi mananca ulei cam 1L la 1000KM dar o si forjez si cred ca orice ulei as baga oricum o sa-l pape.
La urmatorul schimb o sa-i bag Motul sa vad cum se comporta si daca e vreo diferenta.

Re: Castrol vs. Mobil 1
 

Atentie ca nu e tot una Mobil cu Mobil1. E adevarat e aceeasi firma, dar mobil simplu e facut in turcia si e un ulei low-cost; Mobil1 e varful de gama.

La fel si la castrol, magnatec e ala mai simplu iar edge e varful de gama.
Eu am mobil1 0w40 unul din cele mai bune uleiuri de pe piata ca si cifre si indice de vascozitate(atat la cald cat mai ales la rece), dar nu e recomandat la motoare cu km multi (peste 120-150,000km)pt ca o sa il manance ca pe benzina :D.

Re: Castrol vs. Mobil 1
 

tine-ti voi mult si bine dupa vrajala asta de la mecanici ca mai tine inca 20 mii uleiul ... Fabricantul nu a fost prost cand a precizat pt fiecare model de motor timpii de schimb ulei si filtre cat si gradatiile in functie de temperatura ambianta ... O fi mai cu mot fabricantii de ulei ..dar vad ca nici unul nu garanteaza cu banii jos ca uleiul tine atat... multa vrajeala si credulul ajunge precum multi altii sa ramana cu motorul in brate de la depuneri.
Oameni buni cititi in cartea masinii intervalele de schimb alte consumabilelor , constructorul nu a fost prost si a scris in carte intervalele ....
Iar nea caisa mecanic sef care zice ca te mai tine inca 20 mii km uleiul sa se duca la sapa de lemn din partea mea..
In timp uleiul isi pierde din propietati si ajunge sa aiba vascozitatea si ungerea apei ghuivetate...Ce spun ei ca te tine uleiul 200 miii km sunt gogosi de vandut la fraeri. Mai cititi si pune-ti mana pe cartea masinii de invatati

Re: Castrol vs. Mobil 1
 

Nu e joaca cu lubrefiantul.

Re: Castrol vs. Mobil 1
 

Ce ulei diesel, de la mobil 1 e mai potrivit pt o masina cu 120mii km? 5w40 sau 10w40?

Re: Castrol vs. Mobil 1
 

Intre Castrol Edge 5W-30 si Mobil 1 ESP Formula 5W-30 care este mai bun ? Este cert ca ambele sunt uleiuri de top dar unul trebuie sa fie ceva mai bun.

@ lord_wader - Mobil 1 Turbo Diesel 0W-40, 10W40 nu cred ca este Mobil 1 ci Mobil (gama mai ieftina).

Re: Castrol vs. Mobil 1
 

exista si Mobil 1 10w40 http://www.mobiloil.com/USA-English/...ge_10W-40.aspx

Daca e mai ieftin nu inseamna mai prost si sunt motoare in care daca bagi 0W-40 le prajesti.
