If you have had good results with your current oil, we can understand why you may be reluctant to switch motor oil. However, now there is an oil, Mobil 1 Truck & SUV advanced full synthetic motor oil, that is specially formulated for truck and SUV engines with 10 percent more sludge-fighting, anti-wear additive* to provide outstanding performance and protection in normal and more severe driving conditions, such as towing and hauling. All engines generate heat, but hardworking engines can generate additional heat, which can result in oil breakdown, excessive oil consumption (burn-off) or even engine failure.
*Compared to Mobil 1™ motor oil. Additive percentage may not correspond with percentage of engine protection benefits.
