Arch Quantum

0W-8

SQ

Fully Synthetic

Arch Quantum SQ 0W-8 is an SAE 0W-8 fully synthetic petrol engine oil developed for modern gasoline engines with API SQ performance. It is engineered to meet the newest API SQ and ILSAC GF-7 performance standards. It provides outstanding protection against wear, sludge, and LSPI (Low Speed Pre-Ignition), while improving fuel economy and ensuring long-lasting engine cleanliness.

Available Grades

Applications

Recommended for vehicles where the manufacturer specifies SAE 0W-8 with API SQ or equivalent petrol engine oil performance. Suitable for gasoline engines across North American, European, and Japanese manufacturers, including those equipped with turbochargers and direct-injection systems. Suitable for engines requiring API SQ, ILSAC GF-7, or previous categories such as SP and GF-6. Fully compatible with catalytic converters and ethanol-blended fuels up to E85.

Benefits

ARCH QUANTUM SQ 0W-8 delivers measurable performance advantages over previous GF‑6 formulations:

Delivers cleaner pistons with improved oxidation stability and deposit control.
Provides better fuel economy and overall engine efficiency.
Ensures stronger LSPI protection, even under aged-oil conditions.
Minimizes timing-chain wear to help extend engine life.
Enhances low-temperature pumpability for quicker lubrication on startup.
Engineered for full GPF compatibility and readiness.
Offers increased resistance to oil gelation and moisture exposure.
Features improved elastomer compatibility with newly tested materials.

These benefits combine to deliver outstanding wear protection, deposit control, oxidation resistance, and enhanced emission‑system durability for next‑generation engines.
