Diesel oil quickly turning black is the norm, but it doesn't need to be so. It's because there's a lot of contaminates left in the engine. I used Cost Effective's Flush Oil Concentrate on a 30 yr old diesel engine (Hilux 2L). When we ran it after getting all the crud out, I thought we'd forgotten to put oil in, as it was that clean. Engine ran better after this with more power. I don't work for the company, just reckon it's good product.
