While supplies last. Receive a FREE Mobil1 jacket with a 0W-40 oil change. Most wear takes place at engine start-up, especially when it's cold. Mobil 1 flows at very low temperatures, allowing for fast flow through the engine. High Temperature Stability.
High heat oxidizes oil and thickens it.
Mobil 1 resists thickening better than conventional oils, and has special additives that make it even better. Cold Temperature Performance. Mobil 1 flows to at least -55 degrees because it doesn't contain waxes. Sludge formation from oil breakdown can block oil passages and cause piston rings to stick. Mobil 1 provides outstanding deposit and sludge protection.
