What is the best engine oil to use for a Vauxhall Vivaro?

I've been having some trouble finding the right engine oil for my Vauxhall Vivaro. The manual recommends a specific brand, but I've heard conflicting opinions from other owners. What oil do you recommend using for optimal performance and longevity of the engine?

I highly recommend sticking to the brand recommended in the manual. Manufacturers spend countless hours and resources testing which oil works best in their engines. Deviating from their recommendation could cause problems in the long run.

I've been using a synthetic oil and have had no issues so far. It's a bit more expensive but provides better protection for the engine. If you decide to go this route, just make sure to check the oil levels more frequently as synthetic oil tends to burn faster.

I have a friend who owns a Vauxhall Vivaro and he swears by using a high mileage oil. He claims it keeps his engine running smoother and prevents any leaks or buildup.
