I have just purchased a 2010 Thor Serrano 31z with the Maxxforce 7 diesel engine. I would like to change the oil however I can not locate anything that looks like and oil filter. I was told by a local dealer it was the large cartridge on the top was the oil but the brochure says it's a fuel filter. Any of you who do your own service work know where the oil filter is??
