Multi vis will protect the engine over a wider range of temperature extremes. They also tend to have a more comprehensive additive package. Because they are designed to flow well in a wide temperature range, however, if not properly formulated, a multi vis may break down and not protect the engine well under extreme high temperatures.
A single vis will not have this problem but it can only be used in a narrow temperature range. They may not have a comprehensive additive package and thus may not conform to the most recent API or European standard for a given make and year.
Because neither is ‘perfect,’ many opt for synthetic, which will remain stable and can be used year round.
Since temperatures below freezing are rare on the Arabian Peninsula, my recommendation for your car is 20w 50 (multi vis) or synthetic.
