Checking engine oil is a crucial part of car maintenance. It’s essential to understand what engine oil does, the type your vehicle needs, and how to top it up properly.
Different types of engine oil can make it confusing to know which one is right for your car. Using the incorrect oil can damage your engine, so always check your vehicle’s requirements.
Here at Auto Fit Bedford, we have mechanics who can replace your oil and filters, brake pads, and discs, or provide a full vehicle health check. Call us on 01234 215 500.
Engine oil lubricates the moving parts of your vehicle’s engine, reducing friction and heat. Proper lubrication prevents severe engine damage. The oil also cleans the engine by collecting dirt and dust, enhancing engine efficiency and safety. Additionally, motor oil improves fuel economy, cools the engine, and reduces emissions.
Additives in the oil, such as detergents, dispersants, and anti-wear agents, enhance its performance, keeping the engine clean and running smoothly.
Synthetic motor oil, made from synthetic materials like polyalphaolefins (PAOs) and esters, offers superior performance and is suitable for high-performance cars or vehicles needing extended oil change intervals.
Semi-synthetic oil blends synthetic and mineral oils, offering better performance than mineral oil at a more affordable price than full synthetic oil. It’s ideal for vehicles that aren’t driven frequently or are used for short trips regularly.
Mineral oil, derived from crude oil, is the most common and affordable motor oil. It is non-toxic, biodegradable, and prolongs engine life.
Low-SAPS (Sulphated Ash, Phosphorus, and Sulphur) oils have fewer harmful additives, reducing potential damage to the engine. Brands like Shell Rotella T6, Mobil 1 ESP Formula 5W-30, and Pennzoil Ultra Platinum 5W-30 are top choices.
High-mileage oils are designed for vehicles with over 100,000 miles, offering extra protection for older engines. They help reduce oil consumption, leaks, and deposits, extending engine life. Ensure the oil matches your vehicle’s specifications and follow the manufacturer’s recommended oil change intervals.
Oil grades like 10W-30, 5W-30, and 0W-20 indicate viscosity. Multigrade oils, with numbers on either side of ‘W’, adapt to seasonal temperatures and are common in the UK. Oils without a ‘W’ are for summer use.
Viscosity measures oil flow resistance. Higher viscosity means thicker oil; lower viscosity means thinner oil. Choose the correct viscosity as specified in your vehicle’s manual.
Mixing different types of oil can harm your engine. Different oils have varying viscosities and additives that might interact unpredictably. Stick to the same type of oil for top-offs and change old oil completely before adding new oil.
Using the wrong oil can cause overheating, sludge buildup, inefficiency, and leaks. Always use the oil recommended in your owner’s manual.
Most engines require 4-6 liters of oil. Check your owner’s manual for the exact amount. Regularly check your oil level and top up as needed to prevent engine damage.
Typically, change your oil every 6,000 miles. However, this varies based on vehicle type, oil type, and driving conditions. Newer cars with synthetic oil may go up to 7,500 miles, while older cars with conventional oil might need changes every 3,000 miles. Consult your owner’s manual or mechanic for the best schedule.
