It is not advised to combine various types of antifreeze, extended-life coolant, and universal coolant, as these mixtures could be damaging to the diverse metals found in car engines.

Invest in the same brand, concentration, and kind of coolant/antifreeze to safeguard your car’s life each time replenishment becomes necessary.

Generally speaking, you can drive with mixed coolant for several thousand miles without any serious effects.

However, it’s generally advisable to have the mixture completely replaced or completely drained no later than 5,000 miles after mixing.

Which Type Of Coolants Should Be Avoid Mixing Together?

In general, mixing different types of coolants should be avoided.

By combining multiple components to make coolants, a discrepancy within the cooling system can be created, which could lead to severe harm and expensive fixes.

The best approach is to stick with one specific type and brand of coolant and avoid mixing them together.

Can You Mix Coolant Brands?

Of course, if you have to top off a car due to low levels, it’s okay to use a different type or brand as long as it meets the same specifications set forth by the vehicle’s manufacturer.

Making the right product choice or combining a variety of brands can be formidable. 

To guarantee success, it’s best to always seek out advice from an automotive specialist or a reliable mechanic about particular products.

Dos Of Mixing Different Coolant Brands
