Drivers urged to check oil after hot summer

Motorists are being urged to check the oil levels in their vehicles after experts warn the summer heat could have caused it to deteriorate.

The car insurance experts at Quotezone.co.uk are encouraging motorists to check vehicles are roadworthy after the high temperatures of the summer.

Heat alone doesn’t cause oil levels to drop, but it can affect the oil in the vehicle. As temperatures rise, oil decreases its viscosity – meaning it thins and can get around warn seals and piston rings more easily – burning off in the combustion chamber, resulting in higher consumption.

Carrying extra loads during the summer, stop-start traffic and using air conditioning in the vehicle also increase heat, and use more oil.

Hot conditions also speed up oxidation, making oil degrade sooner, losing some of its protective properties.

The experts suggest checking oil at least once a month, before any long journeys and recommend topping up between the minimum and maximum marks without overfilling.

Motorists should also ensure the car is serviced regularly and watch for warning signs including an illuminated oil light, oil spots on the drive, a burning smell and blue tinged exhaust smoke.*

If the vehicle runs out of oil, it could lead to lasting engine damage – drivers may even need to replace the engine which can range from £1,500 to £5,000 depending on the vehicle.**

Modern engines in good condition won’t lose a noticeable amount of oil during a hot spell, so it pays to keep the car well maintained and be wary if the vehicle is older.

The experts are also suggesting other checks drivers should make before cooler autumn weather sets in.

Among them are checking tyres for cracks, bulges and uneven wear, having older batteries tested and reviewing wiper blades.

Greg Wilson, car insurance expert and CEO at Quotezone.co.uk said: “After a summer of high temperatures, it’s sensible for motorists to run a few extra checks, and oil is a good place to start. As well as checking levels, be sure to use the right grade for your engine. Oil that’s too thin won’t protect the engine as effectively, particularly after a hot spell has already put it under strain.

“Tyres, batteries and coolant all take a hit in hot weather too, and the effects often don’t show up until conditions change. A ten-minute check now, covering fluid levels, tyre condition and wiper blades, can catch small issues before they become expensive repairs or lead to a breakdown. 

“It’s also a good time to review your cover, as breakdown assistance and comprehensive insurance can make a real difference if something is missed. Taking a little time now really could save you money later in the year.”

Quotezone.co.uk’s top autumn checks:

Tyres

Heat causes tyres to expand and pressures to rise. Check and adjust for cooler weather. Also look out for cracks, bulges or uneven wear as UV exposure can degrade rubber.***

Battery

Heat accelerates fluid evaporation and internal corrosion in batteries. Consider having it tested if it’s more than three to four years old.

Coolant

Coolant can drop after a summer of keeping the engine cool. Check condition and concentration, not just the level.

Wiper blades

Rubber perishes in strong sun and heat, causing them to smear. Check before autumn rain and debris increases.

Air filters

Dry summer conditions can clog air filters faster than usual. This can impact performance and fuel economy.

Bodywork and paint

Strong UV can fade or damage paintwork. Check for chips or issues before autumn rain arrives.
