If you are accustomed to a passenger car or even a gas RV, your first diesel service appointment may be a bit of a shock. Compared to a gas RV, your diesel may use double or quadruple the amount of oil (1435 quarts). The filters are larger, and there are more of them, plus diesels generally have four batteries instead of two. While each service appointment is more expensive, diesel engines run long and harder without routine maintenance, appointments are also less frequent.
