Causes of poor starting in winter

1. Thick or old engine oil

   At low temperatures, oil becomes more viscous. If the oil isn't suitable for winter conditions or is too old, the starter motor struggles to turn the engine over.

2. Weak battery

   Cold temperatures significantly reduce battery capacity. A battery that was just barely sufficient in summer can cause problems in winter.

3. Clogged filters

   An old or dirty oil filter or fuel filter can cause the engine to run less efficiently, making starting more difficult.

4. General engine maintenance

   Worn spark plugs, faulty glow plugs (for diesel engines), or wear in the fuel system also contribute to starting problems.

How engine oil affects starting

The viscosity of engine oil determines how easily the engine can be turned over during a cold start. 15W40 oil is formulated to stay fluid enough at low temperatures (thanks to the "15W") while providing sufficient protection at operating temperature (the "40").

If you use the wrong oil (too thick or not winter-suitable), you'll notice this especially in winter through difficult starting and increased wear during cold starts.

Solutions for starting problems

1. Use the right oil

   Switch to quality oil that remains smooth even at low temperatures.

2. Replace the oil filter in time

   A clean filter ensures proper oil flow and prevents extra resistance when starting.

3. Check the battery

   Have your battery tested and replace it if necessary. A new battery is often THE solution for winter starting problems.

4. General maintenance

   Check glow plugs, air and fuel filters, and make sure the engine is used regularly to prevent problems.
