Hey folks so some thing just came up on another forum about 10W 30 oil vs 10W 30 diesel oil,my grey Zl2202DT-M calls for 10W 30 on a under the hood sticker,now guessing where I live and my last oil change was just general auto blend (dino/synth) 10W 30,its running a D1402 engine,I am due for a change do I stick with the common oil or change it up to the required 10W 30 diesel oil,thanks.
