Mag1

Mag1 (also styled MAG 1) is a motor oil, lubricants, and automotive chemicals brand owned by Highline Warren (formerly Warren Distribution), headquartered in Omaha, Nebraska. The brand is sold primarily through Walmart, auto parts chains, and other value-channel retailers across North America. Mag1's product range spans conventional and synthetic motor oils, transmission fluids, gear oils, and an aerosol chemicals line that includes brake cleaner, engine degreaser, and the Air Intake & Throttle Body Cleaner.

The brand's positioning is practical and price-competitive — it targets the owner who wants a name-brand product at a budget-friendly price point. Mag1's motor oils are API-certified and routinely appear in cost-effectiveness comparisons on enthusiast forums. The aerosol chemicals line follows industry-standard formulations: the throttle body cleaner uses a light-hydrocarbon solvent blend (heptane and acetone-based) consistent with the category's de-tuned solvent envelope, distinct from the more aggressive aromatic solvents used in carb cleaner products.
