On cars.
My mate uses engine flushing oil at every oil change on his Beemer 330.
My boy has a Fiat Punto and I had to top ip his oil snd noticed a lot of Black goo in the filler cap and on components inside, I'm not sure if it was the rocker assembly or a plate just inside but I could scrape a thick tarry mess of it. Now I'm thinking of flushing it a few times but I heard that diesel did the same job. I thought a few flushes with diesel yhen use a flushing oil.
Anyone know if this is a good or a bad thing to do?
