I put a lot of miles/kilometers on my van and only change the oil and filter in spring and fall of the year. I've been doing it that way for years. Now I hear quality synthetic oils are better and black oil isn't always bad oil. Read some the comments below the article if you like. What do you folks do. One of my friends changes his oil every 3000 kl religiously, his Diesel engine holds 16 quarts. I thought that was a bit excessive myself. Mines a gasoline V8 that tops off with 6 Litres with a new filter.
