sae 5w 30 oil

The listings show full synthetic and synthetic‑blend SAE 5W‑30 formulations, with several products specifically labeled for high‑mileage engines.

The typical container shown is a 5‑quart bottle, listed as 160 ounces net.

At least one full‑synthetic listing explicitly states it meets or exceeds ILSAC GF‑6A and API specifications (including API SP and API SN/SN Plus); another listing references GF‑6‑qualified performance.

Several 5W-30 formulas advertise seal conditioners that help restore flexibility to hardened or shrunken seals, treat and prevent oil leaks, and reduce oil consumption in higher-mileage engines.

Several listings mention low‑friction or anti‑friction additives designed to reduce internal friction, help optimize engine power, and improve fuel economy.
