As temperatures drop, your vehicle's fluids face increased challenges. Cold starts put enormous stress on engines — studies show that up to 75% of engine wear occurs during cold starts. Choosing the right oil and coolant for winter can dramatically extend engine life.
Winter Oil Selection: Lower W-ratings flow better in cold weather. A 5W-30 oil will flow much more easily at -30 degrees Celsius than a 15W-40. For extreme cold climates, 0W-20 or 0W-30 grades provide the best cold-start protection.
Why cold starts matter: When your engine sits overnight in freezing conditions, oil drains from critical components. At startup, the engine runs momentarily without full lubrication. Thinner oils reach these components faster, reducing wear.
Coolant and Antifreeze: Your coolant system is equally critical in winter. A proper 50/50 mix of antifreeze and water protects to approximately -37 degrees Celsius. Our i-GlooKool range offers both pre-mixed (30/70, 40/60, 50/50) and concentrated antifreeze products.
Key winter fluid checks: - Engine oil viscosity appropriate for local temperatures - Coolant concentration tested with a refractometer - Windshield washer fluid rated for freezing temperatures - Battery condition (cold reduces battery capacity by up to 50%)
At i-GlooOil, our DIAMOND 5W-30 and 5W-40 fully synthetic oils, combined with our i-GlooKool antifreeze products, provide comprehensive winter protection.
