What is the best oil to use for a Ford Transit Custom engine?

I recently bought a Ford Transit Custom and I'm not sure what type of oil to use for the engine. Can someone recommend the best oil for improved performance and longevity?

For a Ford Transit Custom, it is recommended to use synthetic oil with a viscosity of 5W-30 or 5W-40. These oils provide better protection and performance for the engine. Make sure to also check your owner's manual for the specific oil requirements for your vehicle.

I've been using Castrol EDGE 5W-30 for my Ford Transit Custom and it has been great. It's a bit more expensive, but definitely worth it for the added protection and performance.

I highly recommend using Mobil 1 5W-40 for your Ford Transit Custom. It's a bit pricier than other oils, but it's extremely high quality and will keep your engine running smoothly.
