Which oils in 0w/5w30 carry the "prestige" that M1 0w40 holds? In May, it will be a year since I changed the oil and have only driven about 4k to date. I thought I'd give the 0w40 a try, but Toyota does call for a 5w30. I haven't had any issues with the 0w40, but I just got to wondering what oils could be compared.
Thanks!
Thanks!
