Questions, answered.
The essentials on grades, standards and orders. For anything specific to your vehicle, check the handbook or ask us.
How do I know which viscosity my car needs?
Check the owner's manual or the oil filler cap. It states the required viscosity grade (for example 5W-30) and the manufacturer approval. Match both and you are within specification.
What do the two numbers in 5W-30 mean?
The first number with the W is the cold-flow rating: lower stays thinner at low temperature, so oil reaches the bearings faster on a cold start. The second is the viscosity at operating temperature. Both are defined by the SAE J300 standard.
What are ACEA and API classes?
Performance standards, not viscosity ratings. ACEA is European (for example C3 for engines with a particulate filter), API is American (for example SP for modern petrol engines). Your handbook lists the required class.
Can I mix different oils or brands?
It is best to stay with one viscosity grade and approval. Topping up with an oil of the same specification is fine; avoid mixing different types where you can. When in doubt, do a full change with a single product that meets your handbook's requirement.
How often should I change the oil?
Follow the service interval and oil specification in your vehicle handbook. It varies by engine, oil type and how the car is used, so the handbook is the reference that applies to your car.
What are the delivery and return terms?
Our shipping and refund policies are linked in the footer and at checkout. Those pages are the binding terms for every order.
