Can you combine different types of car oils?
Yes, combining different types of car oil is possible, but it’s usually not recommended unless necessary. Motor oils have different viscosities, additives, and formulations tailored to specific engine needs.
Mixing them can dilute these benefits and may reduce the oil’s overall performance. If you need to top up your oil and don’t have an exact match, using a compatible type of oil in small amounts is okay.
For example, combining synthetic and conventional oils can work in a pinch if you’re low on oil, but it’s best kept as a temporary solution.
Synthetic oils are engineered to offer superior performance, including better high-temperature stability and longer-lasting lubrication. Mixing in conventional oil may reduce these benefits, impacting the oil’s longevity and ability to protect your engine.
For optimal results and to maintain your engine’s performance and longevity, always use the same type and viscosity of oil recommended in your vehicle’s owner’s manual.
Sticking to the specified oil type ensures your engine receives the proper lubrication, temperature control, and wear protection.
Using the correct oil also helps keep your warranty intact and can improve fuel efficiency. Regular oil changes with the proper oil type will help keep your engine running smoothly and avoid potential issues caused by oil breakdown or buildup.
