Do I need different engine oil for diesel and petrol engines ?

Generally the answer is yes for older vehicles, as diesel engine oils have higher detergency levels. It is important to refer to your vehicle manufacturer’s handbook to establish exactly which specification of oil is required. This is vital if your car has extended service intervals and you are still within the warranty period. New vehicles are designed in a way that allows the same oil to be used whether the…

Do I need to use a different type of oil filter with synthetic oil ?

The current generation engines, being compact are running at very high temperatures. Measuring the viscosity at 100°C was not too representative of the temperatures reached today by the latest generation of engines. Therefore a standard test was introduced to measure viscosity at 150 °C, and under a high shear rate, so as to really examine the ability of the oil. Hence what HTHS (High Temperature, High Shear) viscosity stands for,…
