What product categories does Dataoil cover?

Nine categories: automotive engine oils, gasoline fuel additives, diesel additives, engine oil additives, motorcycle oil, AdBlue (diesel exhaust fluid), coolant (engine coolant) and glass washer fluid, plus transmission & gear oil. Engine oils and additives all use premium major-manufacturer synthetic base oils with core Afton additive products, produced at the company's controlled production base (ISO 9001 certified).

What viscosities and API grades does Dataoil engine oil cover?

Viscosity grades span 0W-20 to 5W-40, covering mainstream gasoline-oil API specs (see each product's spec card in the Product Center). The 9000 series is the flagship GTL-ester line; other series use premium major-manufacturer synthetic base oils. Start from your vehicle handbook's viscosity grade and API spec, then use the oil-finder tool or ask customer service.
