TL;DR: Know the grade, don’t mix randomly, top up slowly, and advise service intervals — when unsure, check the owner’s manual.
Viscosity: What 5W-30 Means
5W is cold-flow rating; 30 is hot viscosity. Use the grade recommended by the manufacturer to protect the engine in local temperatures.
Service Intervals
Typical range is 5,000–10,000 km depending on oil type and vehicle usage. For severe conditions (dust, short trips), intervals are shorter.
Safe Top-Ups at the Forecourt
- Confirm engine warm or cool and vehicle parked level
- Check dipstick; top up slowly and re-check level
- Wipe spills immediately; avoid overfilling
Customer FAQs
- “Can I mix 5W-30 and 10W-40?” Small top-up in emergency is usually fine, but not ideal long-term.
- “What oil is best?” Use the manufacturer’s spec first. Synthetic often lasts longer.
- “Oil light came on.” Stop engine ASAP; check level or call for service.
