The abrasive soot particles found in black diesel smoke are also in the engine oil, where it acts as a grinding paste, wearing away metal from every lubricated part of the engine. Find out more www.costeffective.com.au
Actually the black smoke is from a carbon based fuel aka diesel in and environment that has a lot of heart and is in a low oxygen environment aka the engine that causes the carbon to show its darkness and the oil you can put brand new oil in the vehicle and new oil is normally a golden type color and you can pull the dip stick out and the new oil is black the reason is diesel engines are naturally dirty due to the fuel.
Hi Brid, I haven't talked to you in person yet, only by email. Have spoken to Jimmy a little. Having a petrol, I am having great experiences with the FTC on my stock 2002 Gen 3 5.7 Litre V8 in my holden commodore. Looking forward to seeing what my spark plugs look like when I remove & change over with more powerful plugs :) I'll put information up on your fb wall.
