What does C2 mean on oil?
Mid SAPS
C2: Mid SAPS-Level engine oils, C2 oils are intended for use as catalyst compatible Oil at extended Drain Intervals that are designed to be capable of using low viscosity Oils with a minimum HTHS Viscosity of 2.9 mPa*s.
Is C2 oil better than C3?
Example – an ACEA C2 engine oil will provide better fuel economy that an ACEA C3 engine oil, but may not provide the same protection levels due to the lower film strength. ACEA C grade oils are for the most, not interchangeable with one another depending on the particular applications.
What is C2 and C3 oil?
In Europe, according to the ACEA, low ash oil is labelled as C1 (0.5% ash), C2 (0.8% ash – better suited to higher performance engines) and C3. So an engine oil labelled 5W30 C1, C2 or C3 is a 5w30 grade oil suitable for cars fitted with DPF’s.
Should you use thicker oil in an older engine?
You should switch to thicker oil if your older car is consuming oil. The general rule is to always use the viscosity your car manufacturer recommended. As your engine gets older, the clearances within the engine change due to wear and tear, and your car could start to consume oil.
Should I use 10w30 or 5w30?
5w30 provides better lubrication compared to 10w30. It is best suited for private vehicles and light-duty diesel and petrol engines, while 10w30 is more suitable for commercial vehicles and other cars with heavy load engines.
Will it hurt to put 10W30 in a 5W-30 engine?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
Is 5W-30 or 10W30 better for winter?
10w30, the thinner 5w30 will circulate quicker, and flow through bearing tolerances better during an engine startup in the winter or colder climates. The “w” behind the five and the 10 indicates that those are the viscosities in colder or winter temperatures.
