MotorBabuWinter care for your car and bike
Cold mornings are hard on batteries, tyres and starters — and fog makes every trip riskier. A 15-minute check now saves you a dead battery on the coldest day.

The 15-minute winter checklist
| Check | What to look for |
|---|---|
| Battery | Slow cranking, dim lights at start-up, white or green crust on the terminals. Over 3 years old? Get it tested. |
| Engine oil | Level between the marks; oil change not overdue. Old oil is harder on a cold engine. |
| Tyre pressure | Check cold, in the morning — it drops as temperatures fall. |
| Coolant (cars) | Level between MIN and MAX in the reservoir, mixed as the manual says — important for hill trips. |
| Lights | Headlamps, fog lamps, tail lamps and indicators all working and clean. |
| Wipers and washer | Blades that clear without streaks; washer fluid topped up. |
| Demister and blower (cars) | Windscreen clears quickly with the AC/blower on. |
Battery: the number-one winter failure
Cold makes a battery deliver less power at the same time a cold engine needs more to turn over. Signs it's on its way out: the starter cranks slowly, the lights dim while starting, or the vehicle needs several tries on cold mornings. Most car and bike batteries last about 3–4 years.
- Clean any crust off the terminals and make sure they're tight.
- If the vehicle stands for days, start it at least once a week, or take it for a short drive.
- Over three years old? Many battery shops test it free — better than a dead battery on a foggy morning.
Engine oil and cold starts
Stick to the grade in your owner's manual — multigrade oils are designed for cold starts, and there's no need to switch for an Indian winter. What matters more is that the oil isn't overdue: old oil protects a cold engine less. After starting, give the engine 30–60 seconds before riding or driving off gently; long idling isn't needed.
Tyres
Air contracts in the cold, so pressures drop — roughly 1 psi for every 5–6 °C. Check them in the morning, before you've driven, and set them to the figure on the door pillar label (cars) or in the manual (bikes). Worn tyres are riskier on damp, foggy roads, too.
Driving and riding in fog
- Low beam, not high beam — high beam bounces off the fog. Use fog lamps if you have them.
- Slow down and leave a long gap. Follow the road's edge markings, not the tail lights ahead.
- Keep the windscreen clear — AC on with the blower aimed at the screen clears mist fastest. Riders: an anti-fog visor or pinlock helps.
- Hazard lights only when stopped — and stop well off the road, never in a lane.
- Be seen on a bike: headlamp on, reflective strips on your jacket or helmet.
Let reminders do the remembering

Questions people ask
Why does my battery die in winter?
Cold slows the chemical reaction inside a battery, so it delivers less power — just when a cold engine needs more to start. A battery that was weak in summer often gives up on the first cold morning. Most last about 3–4 years.
Should I change to a thinner engine oil in winter?
No — use the grade in your owner's manual. Modern multigrade oils (like 10W-30 or 0W-16) are made to flow on cold starts, and Indian winters are well within their range.
Does tyre pressure drop in winter?
Yes. Air contracts in the cold — roughly 1 psi for every 5–6 °C drop. Check pressures in the morning, when the tyres are cold, and top up to the figure on the door pillar or in the manual.
Should I use high beam in fog?
No. High beam reflects off the fog and blinds you. Use low beam and fog lamps if you have them, slow down, and keep a long gap to the vehicle ahead.
Can I use hazard lights while driving in fog?
Keep hazard lights for when you've stopped. While moving they hide your indicators, so others can't tell when you turn or change lanes.
