Tod mundo aqui fala que usaram o 5W-40 nas suas trocas.
Grato

Isso não é verdade. Olhem no manual, os números indicam a capacidade do óleo em manter suas características nos limites de temperatura. O 10W40 deve servir, veja os limites no manual...AdemirPinto escreveu:Vi falar que o 10W-40 é mais viscoso que o 5W-40, isto é verdade? Isso não pode dar algum problema no meu carro?

1. Standards in force
The classification of the engine oils is established by the following recognised bodies :
S.A.E. : Society of Automotive Engineers
API : American Petroleum Institute
ACEA : Association des Constructeurs Europeens d'Automobiles
2. S.A.E. standards
2.1. The choice of engine oil grade depends on the climate of the country .
2.2. Recommended viscosity grades
The choice of the various viscosity grades is again linked with a use which conforms to the types of climate. For example, the use of grade 10W 40 is limited to temperate countries (from -17 °C to +37 °C) or countries which have a hot climate .
3. ACEA standards
3.1. Petrol and diesel mixed oils recommended by PSA
The meaning of the first letter does not change, it always refers to the engine type:
A = Petrol and petrol/LPG dual fuel engines
B = Diesel engines
Types of oil :
3 = High performance oils
4 = Oils specific to certain direct injection diesel engines
5 = Oils with very high performance, favouring lower fuel consumption
Examples :
ACEA A3/B3 : High performance and petrol/LPG dual fuel mixed oils
ACEA A5/B5 : Blended oils with very high performance, for all engines, favouring fuel economy
CAUTION : Since 2004, the ACEA has imposed mixed oils : A1/B1 , A3/B3, A3/B4, A5/B5 . Therefore, all
lubricants recommended by PSA are mixed ; There are no longer any specific petrol or diesel oils .
3.2. Introduction of oils which have a low ash content ( LOW SAPS )
Oils which have a low ash content permit limiting of the ash at the exhaust and therefore contribute to increasing the service life of the particle filter. The ash content changes from 1,3 % in current oils to 0,8 % in these new oils (maximum authorised values) .
New ACEA specifications
C3 : Moderate ash content
C2 : Moderate ash content and fuel economy
C1 : Very low ash content and fuel economy
The C2 oil, specific to PSA, corresponds to a request to reduce ash within a reasonable cost limit while retaining the required fuel economy. The C2 oil is a petrol and diesel mixed oil with fuel economy most particularly suited to engines fitted with a particle filter .
4. API oil standards
The meaning of the first letter does not change, it always refers to the engine type :
S = Petrol and petrol/LPG dual fuel engines
C = Diesel engines
The second letter corresponds to the evolution level of the oil (in rising order).
Example : The standard SL is stricter than the standard SJ and corresponds to an improved level of performance.
5. Quality of the engine oils
The engine lubrication oils are classified in line with 3 quality levels :
Mineral oil or level 1 PSA
Semi-synthetic oil or level 2 PSA
Synthetic oil or level 3 PSA
