We don't just supply lubricants — we diagnose failure modes, assess duty cycles, and prescribe the exact formulation. Where uptime, efficiency, and extended machine life are non-negotiable, Banesto engineers are trusted to deliver.
Generic oils fail under demanding conditions. Banesto's Lubricants Division was created to fill exactly that gap — with engineered formulations that stand up to heat, load, dust, and washout. Our approach is systematic and science-backed.
Every Banesto lubricant recommendation begins with kinematic viscosity testing, thickener compatibility checks, and application-specific load–speed analysis — before it ever reaches your machine.
Each thickener family has a distinct performance signature. Selection is never generic — it is dictated by temperature range, speed, load, environment, and re-lubrication interval. These profiles are the starting point for every Banesto grease recommendation.
Base oil selection defines oxidation stability, viscosity-temperature behaviour, and seal compatibility at the molecular level. Banesto engineers apply ASTM D341 viscosity-temperature modelling and OEM compatibility data to select the right base stock for every system.
Every Banesto formulation recommendation is anchored to published international standards. These are not marketing claims — they are the engineering references our team applies when specifying a lubricant for your application.
From individual bearing analysis to full fleet lubrication planning — Banesto's engineering approach scales to match the complexity of your operation without compromise.
Consult Our Engineers →Free online Viscosity Index calculator (ASTM D2270) — enter KV40 & KV100 to instantly get VI, ISO VG grade, and oil quality rating. Also includes a grease thickener compatibility checker. No login required.
Enter your oil's kinematic viscosity at 40°C (KV40) and kinematic viscosity at 100°C (KV100) in cSt. The calculator instantly returns the Viscosity Index per ASTM D2270 Procedure A, the corresponding ISO VG grade, and a quality classification from Low-VI mineral to Full Synthetic.
What is Viscosity Index? VI is a dimensionless measure of how much an oil's viscosity changes between 40°C and 100°C. A higher VI means smaller viscosity change — and more consistent lubrication film thickness across the operating temperature range. Conventional mineral oils typically achieve VI 90–110; PAO synthetics reach 140–160+.
Common VI ranges: Below 80 (Low-VI), 80–110 (Conventional mineral), 110–130 (Group III / semi-synthetic), above 130 (Full synthetic PAO/ester). This free online tool uses the published ASTM D2270 L and H reference tables — the same standard used by lubricant laboratories worldwide.
