Most options are sold in 5-quart (160 fl oz) containers; at least one option is available in a 1-quart bottle.
They commonly advertise stronger wear protection, deposit defense, heat protection, and broader protection against wear, friction, heat and deposits; some also highlight contamination protection and engine‑cleaning additives.
High-mileage 0W-20 formulas typically include premium seal conditioners to help prevent or treat leaks, additives to reduce oil consumption, and anti-wear plus heat‑stability boosters to protect aging engine components.
Hybrid-focused formulas describe ingredients that help manage water contamination (e.g., suspending water molecules), provide anti‑corrosion protection, and include additives to defend against sludge, deposits, friction, heat and wear.
Full synthetic 0W-20 oils are described as flowing more easily at low temperatures to reduce cold‑start wear and as offering enhanced wear protection across a wide temperature range.
