With my Dyslexia I attempted to read 16 pages, but
Last year I filled with 5w-30 Edge Oil. I drive a 2004 XC90 with a mere 173k on the clock.
I guess I’m right in thinking 5w-30 is an ok oil for my age of XC90 in the British Climate. Going by the graph I could even go for 5w-40 as long as its complying with the Grade.
