If you're car is 2005 this oil would seem to me to be overkill as it's for cars with automatic stop/start facility. **Q: Is this suitable for bmw 116i?** A: I have used this brand of oil for several years in my Jaguar car and found it very good. However Jaguar cars must use type A5 BMW cars must use the type C3 as these two types of oil cannot be mixed. As I do not have any experience with BMW cars I cannot make any other comments **Q: Can this be used for Audi A3 diesel 2005 and bmw 3 series diesel 2005?** A: My one is BMW 3 Series petrol. Works well with it.Thanks **Q: Does it suitable vw Passat tdi** A: Yes it is suitable ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great price and quality *by P***Y on 19 June 2026* Good product top quality ### ⭐⭐⭐⭐⭐ Great lubricant *by A***Y on 8 June 2026* If you car has the auto on/off the this is the oil to use.
