A single plant rarely uses one oil — engine, hydraulic, gear, compressor, and grease all differ. Shell covers every family under one brand: Rimula (heavy-duty diesel), Tellus (hydraulic ISO 22-100), Omala (industrial gear ISO 68-1000), Corena (compressor), Gadus (grease NLGI 0-3), Diala (transformer), Turbo (turbine), Mysella (gas engine). Choose by the OEM-specified grade or match like-for-like — SAHA carries Shell as a main brand alongside SK ZIC, quote-based with full tax invoice.
A factory almost never runs on a single oil — vehicle and genset diesel engines need engine oil, presses and cranes need hydraulic fluid, gearboxes need gear oil, compressors need compressor oil, and pivots and bearings need grease. Buying from one brand that covers every family cuts the number of vendors, reduces picking errors, and makes spec comparison easy. This article maps the Shell families SAHA carries as a main brand (alongside SK ZIC), with a job-first selection guide.
Choose by the "job", not the name
Plant buyers usually know the job first (which machine, which problem) rather than the oil grade. Start from the job, then match the family:
| Job / machine | Shell family | Example grades | Reference spec |
|---|---|---|---|
| Heavy-duty diesel/CNG engines (trucks, fleets, gensets) | Rimula | R2NG (CNG), R4X, R4 Plus (synthetic), R5LE (Euro low-emission) | API CI-4/CJ-4, MB 228.31, Volvo VDS-4 |
| Hydraulic systems (presses, cranes, injection) | Tellus | S2 MX (general), S3 M (zinc-free), S4 ME (long-life) | ISO VG 22-100, DIN 51524 HLP |
| Industrial gearboxes | Omala | S2 GX (mineral), S4 GXV (synthetic), S4 WE (worm) | ISO VG 68-1000, AGMA/DIN 51517-3 |
| Air compressors | Corena | S2 P (piston), S3 R (screw), S4 R (synthetic) | ISO VG 32-150 |
| Multipurpose / EP grease | Gadus | S2 V100/V150C/V220, S3 V220C/V460/V460D | NLGI 0-3 (EP / Li-complex) |
| Transformer / switchgear | Diala | S4 ZX-I (inhibited) | IEC 60296 |
| Steam / gas turbine | Turbo | T, S4 GX (GTL) | ISO VG 32-68 |
| Stationary gas engine | Mysella | S3 S/N, S5 N/S (low/medium ash, sour gas) | SAE 40 |
| Vehicle gear / axle / transmission | Spirax | S2 G (GL-4), S2 A (GL-5), S4 CX/TXM | API GL-4/GL-5, UTTO |
| High-speed bearing & circulating | Morlina | S2 BL (ISO 10), S2 B (ISO 32-320) | ISO VG 10-320 |
Where people pick the wrong oil
- Swapping hydraulic and gear oil — hydraulic (Tellus) prioritizes anti-wear + fine filterability; gear (Omala) prioritizes EP + high viscosity. Using the wrong family wears pumps or gears fast. Follow the equipment maker's spec.
- Wrong ISO VG viscosity — a worm drive specified for ISO 460 will overheat and wear if filled with ISO 150. Always match the ISO VG number first.
- Wrong grease NLGI — NLGI 2 is the standard for general bearings, NLGI 0-1 for automatic/cold grease systems, NLGI 3 where you need the grease to resist slumping.
- Wrong ash level on gas-engine oil (Mysella) — low ash for clean gas, medium ash for contaminated gas, sour-gas grade for acidic streams. The wrong choice damages valves and combustion chambers.
Cross-reference against SK ZIC
SAHA carries both Shell and SK ZIC as main brands — if your plant already runs SK ZIC or another brand, send the current part number and we'll cross it to a Shell grade (or vice versa) on the same standard and viscosity. Cross-reference criteria: API/ACEA (engine), ISO VG + DIN 51524 (hydraulic), API GL (vehicle gear), NLGI + thickener (grease). A correct cross-reference must also check OEM approvals, not just viscosity — we verify that before quoting.
Ordering
Pricing is quote-based by grade and quantity — send (1) the Shell grade you need or your current part number, (2) volume + pack size (pail/drum), (3) delivery province. Full tax invoice issued, credit terms for registered companies, nationwide delivery. For food/pharma plants needing NSF H1 at food-contact points, see the Bechem food-grade line alongside.
