Engine oil does a lot more than just “lubricate,” though that’s a big part of it. It cools the engine by carrying heat away from moving parts. It cleans, picking up dirt and combustion byproducts. It seals the pistons and cylinder walls, helping to maintain compression. And it actually helps protect against corrosion, coating metal parts to prevent rust and wear. Basically, it's the lifeblood of your engine. Think of your engine as having all these metal parts constantly rubbing together at high speeds. The oil creates a film between those parts, preventing metal – on – metal contact. Without it, you’d have rapid wear and tear, overheating, and eventually, engine failure. It’s circulated by the oil pump throughout the engine, reaching everything that needs lubrication. You'll notice if the oil is low because the oil pressure light will come on, and that’s a serious warning. Well, regular oil changes are the single best thing you can do to extend the life of your engine. The oil breaks down over time, gets dirty, and loses its ability to protect effectively. It acts like a shield, but even shields wear out. If you skip oil changes, that wear starts happening to the engine itself, and repairs get very expensive, very quickly. Different vehicles need different types of oil – weight, synthetic vs conventional – so it's important to use what the manufacturer recommends. You can find the right oil for your vehicle on sites like Fixparts Online; they usually have a lookup tool to help you. But keeping up with oil changes is genuinely the biggest single thing you can do for long – term engine health. Backed by experts: Engine Oil (MPN A990989140019FBDE) includes a 12-month warranty!
