Hello,
I have a 1988 Mercedes 420sel and it seems that I can use 10W-40, 15W-40, or 20W-50. Considering going with 15W-40 but only diesel options and the two I’m considering are in the title. I know little of oils compared to most on this site and am curious what the experts think. Could not find HTHS of t6 but amsoil’s seems to be around 4.5? Thanks in advance.
