Automotive Chemicals & Lubricants

Automotive Chemicals & Lubricants keep vehicles running smoother, longer, and safer by reducing friction, managing heat, sealing components, and preventing corrosion. It covers engine oils (synthetic, semi‑synthetic, and mineral), greases, brake fluid, coolant/antifreeze, transmission and gear oils, power steering fluid, fuel treatments, and targeted products like cleaners, degreasers, rust penetrants, gasket makers, threadlockers, sealants, anti‑seize, and dielectric grease. For DIY drivers and professional mechanics alike, the right fluid or additive helps protect expensive parts, restore performance, quiet noises, and simplify tough jobs like freeing seized fasteners or sealing a stubborn leak.

Choosing engine oil starts with the owner’s manual: match API/ACEA specs and viscosity grades such as 0W‑20, 5W‑30, or 5W‑40 to climate and driving style. Modern engines often require OEM‑approved low‑SAPs or dexos‑certified oils. For brakes, use the specified DOT rating (DOT 3, DOT 4, or DOT 5.1) and never mix silicone‑based DOT 5 with glycol fluids. For cooling systems, stick to the recommended coolant chemistry (IAT, OAT, HOAT) and avoid mixing types. Gear and transmission oils should meet GL ratings or manufacturer approvals to protect synchronizers and hypoid gears.

Application matters as much as product choice. Use pumps, funnels, and measured dispensers to prevent contamination and overfilling. Grease guns with the right nozzle reach tight fittings; lithium complex or moly greases suit bearings and chassis points. Penetrating oils break rust bonds before fastener removal; follow with anti‑seize on reassembly. Threadlockers secure bolts against vibration, while gasket makers and RTV sealants require clean surfaces and proper cure times. Fuel system cleaners help restore MPG and reduce hesitation.

Watch fluid color and odor; burnt smells, metal glitter, or milky emulsions signal service. Follow intervals, store containers sealed and cool, recycle used fluids, and wear gloves and eye protection to avoid skin contact and splashes on painted surfaces during maintenance.
