Can I use Prestone Dex-Cool Extended Life antifreeze?

You probably could, but most of us stick with Toyota Red or Pink coolant.

Antifreeze has different chemical compositions depending on the type of antifreeze used. Inorganic Acid Technology (IAT) antifreeze can be either ethylene glycol (EG) or propylene glycol (PG). Organic Acid Technology (OAT) antifreeze is primarily ethylene glycol (EG) based. Hybrid Organic Acid Technology (HOAT) antifreeze is a combination of Inorganic Acid Technology (IAT) and Organic Acid Technology (OAT).

Antifreeze colors include red, orange, yellow, pink, blue and green. Different colored antifreeze is used to identify the type of antifreeze being used.
Inorganic Acid Technology (IAT) antifreezes are green in color.
Organic Acid Technology (OAT) antifreezes are orange, red, green, pink or blue.
Hybrid Organic Acid Technology (HOAT) antifreezes are orange or yellow in color.

Here is a link about using and mixing the different kinds of antifreezes:
