I recently purchased a Vauxhall Vivaro and I am not sure what oil viscosity to use for optimal engine performance and longevity. Should I go with a 5w-40 or a 10w-40? Will using a higher viscosity oil have an impact on fuel efficiency? Any advice would be greatly appreciated!
ReplyIt is recommended to use a 5w-40 oil for a Vauxhall Vivaro as it is a popular and trusted viscosity for this type of engine. It offers good stability and lubrication for both cold and hot weather conditions. Using a higher viscosity oil, such as 10w-40, may increase fuel consumption and could potentially cause engine damage. Stick with the recommended viscosity for the best results.
I've been using 10w-40 oil in my Vauxhall Vivaro for years and haven't had any issues. It offers good protection and I haven't noticed a significant difference in fuel efficiency. It is a more affordable option compared to 5w-40, but ultimately it's up to personal preference.
As a mechanic who specializes in Vauxhall vehicles, I highly recommend sticking with the manufacturer's recommended viscosity of 5w-40. It is specifically designed for optimal performance in your vehicle's engine. Any deviations could lead to potential problems down the road. Trust in the experts and stick with the recommended oil.
