engine synthetic oil

These oils are formulated for high‑mileage engines, European gasoline and diesel vehicles, and hybrid vehicles.

Product descriptions reference industry approvals such as ILSAC GF‑6A, API SP and API SN (including SN Plus), and various European ACEA specifications.

Many formulas include premium seal conditioners designed to restore flexibility to hardened or shrunken seals, which can help reduce oil leaks and minimize oil consumption over time.

Available SAE grades shown include 0W‑20, 5W‑20, 5W‑30, 10W‑30, 5W‑40, and 0W‑40.

High‑mileage formulas advertise stronger wear protection (examples cite roughly 50–70% better), improved sludge defense (around 20% better), markedly better heat protection (often described as multiple times better, e.g., roughly 2.5×–20×), and inclusion of seal conditioners to help treat and prevent oil leaks.

Most listings show 5‑quart containers; product details list a net weight of 160 ounces.
