wow I just finished reading through this thread and I cannot believe how inexpensive oil changes are on the west coast and the US. I don't go to my Ford dealership except for warranty work. I have a 2008 Mustang Bullitt takes 5.7 Litres 5w20 like the 2014 edge we have. At the dealership they charge $109.99. I can get Penzoil or mobil one at Canadian Tire or parts source when on sale for $39-45 depending on the sale. I will change it my self but if the oil is due in winter I go to the 10minute penzoil change and they charge $34.99 to change the oil wit hmy oil and filter which works out to $75 or more. I wish we had a place around here that would do an oil change for the price you guys are paying. With my Bullitt I change it every 6 months or 8,000 km. With the edge I am going to rely on the on board computer, right now we have 3100km and change and the computer says 83% left so with the average at 4,000km per 20% oil wear it should last 20,000km? sounds a bit long of an interval but I will keep an eye on the level and would not go more than 10,000km or 6 months. A buddy of mine has a 2013 BMW 328 and his first oil change was at 16,000km dealer said thats normal? Wow I am old school and would always go 3 months or 5,000km. Time have changed but so have the prices and quality of the oil and engine.
