Engine Oil
All modern engine oils are formulated and marked to comply with various world standards, whether API, ILSAC, ACEA or JASO. All of these various standards were developed to meet car manufacturer requirements as well as national government standards for emissions. Depending on your car’s specific requirements, you may need a full synthetic oil, a synthetic blend or if your car is older a conventional oil. The Castrol line of engine oils are available in a number of oil viscosity ranges, types and standards which are clearly noted and marked on the containers. The days of going to the local store for the cheapest 10W-30 oil are long gone, using the wrong oil in your engine can cause severe and expensive damage. You can depend on Castrol to have the exact oil you need. Check your owner’s manual to verify the exact viscosity range and compliance standard required for your oil change.
Differential Oil
The differential in your car is what drives the wheels, converting the driveshaft rotation through a series of gears and in turn rotating the axles. The differential housing contains a much higher viscosity oil than say an engine oil, usually between 65 and 100 weight depending on the manufacturer’s requirements. But as with engine oil there are world standards and markings to show compliance with the various differential oil standards. The Castrol line of differential oils are all manufactured to the specific requirements of these standards and marked on the package so you can be assured of compliance with your car manufacturer’s factory requirements. As with engine oil, check your owner’s manual for the exact viscosity and standard needed for your car’s differential oil.
Hydraulic System Fluid
Cars can have varying uses for hydraulic system fluid depending on year, make, model and options installed. Many European cars come from the factory with Castrol hydraulic system fluid used in the power steering system and models that have a hydropneumatic suspension may also have it. Hydraulic fluids have specific requirements for viscosity, boiling point, temperature range, etc depending on the usage. The Castrol hydraulic system fluid that may be specified for your car meets or exceeds the factory requirements so you can be sure it will perform up to the same level as the original. Check out the AutohausAZ catalog listing for your car and look for the Castrol brand the next time your need fluids for your car.
