FAQ

How do I choose the right engine oil or additive for my car?

Start with your owner’s manual specs and approvals (API, ACEA, and OEM approvals like BMW LL‑01, MB 229.5, VW 502 00).

  • Hybrids and daily commuting: 0W‑20 or 5W‑30 (API SP / ILSAC GF‑6A)
  • European or high‑temp/high‑load use: 5W‑40 (ACEA A3/B4 with relevant OEM approvals)
  • Gasoline injector cleaning: choose “Injector Cleaner” (gasoline only)
  • Diesel care: “Super Diesel Additive” (safe for vehicles with or without DPF)
  • If unsure, contact us with your car model, year, and engine code for a quick recommendation.
How often should I use fuel additives? Will they harm the engine or catalytic converter?

When used as directed, they’re safe and compatible with catalytic converters and O2 sensors.

  • Gasoline injector/fuel system cleaner: every 2,000–3,000 km or every 2–3 tanks
  • Diesel additive (cetane boost and injector cleaning): every 2,000–3,000 km or before long trips
  • Always follow the label dosage (e.g., 300 ml treats ~70 L; 250 ml treats ~75 L). Do not overdose.
