Most engine wear happens in the first few minutes after startup, up to 71% in some tests. At -20°C, 5W-40 circulates faster than 15W-40. This is the reason why owners of trucks and […]

Both are high-quality full synthetic oils that meet or beat the standards of modern engines. The biggest difference between them shows up at low temperatures. Amsoil claims better numbers on cold-flow tests. Some

Cold temperatures make gear oil thicker. In freezing weather, standard 75W-90 oil can get so thick it barely flows. Gear oil that can flow in cold weather is important because your gears and

Robert H. Wehman founded Spectro in 1966 after solving fuel-to-oil mixture problems for SAAB, a Swedish car company. He applied this engineering expertise to 2-stroke motorcycle oils, creating formulations that addressed smoking and
Standard DOT 4 brake fluid gets thick in freezing temperatures, and that causes a real problem in modern cars. Most vehicles now rely on computer-controlled safety systems like anti-lock brakes (ABS) and electronic

You do not need a hybrid-specific formula. Any standard synthetic 0W-16 oil is safe to use as long as it meets the API SP and ILSAC GF-6B (or newer) specifications listed in your

Low-speed pre-ignition (LSPI) happens when the fuel-air mixture in an engine cylinder ignites on its own, before the spark plug fires. This is abnormal combustion, and it shows up mostly in modern, downsized

Riders pick heavy-duty diesel engine oil (HDDEO) over motorcycle-specific “4T” oil for two main reasons: price and availability. Dedicated motorcycle oils cost more and can be hard to find, but diesel oils like
VG (Viscosity Grade) measures oil thickness. Higher numbers mean thicker fluid. ISO VG 22 is a thinner grade suited for cold conditions, since thick oil in low temperatures causes pump starvation and wear.
