NAPA Ultra LL Sp-Oat 64 (20L) (N91620L)

Description

Genuine NAPA · Part no. N91620L

Safety: Warning. Harmful if swallowed. May cause damage to organs through prolonged or repeated exposure. Read the label before use.

NAPA Ultra LL Sp-Oat 64 (N91620L) is a silicated-phosphated OAT (PSi-OAT) coolant concentrate for engines whose makers specify that chemistry. It comes in a 20 litre drum, is diluted with water before filling, freezes at -37.5°C at 50% dilution and carries a 5-year protection rating.

Good to know

• How is it different from plain P-OAT? It adds silicates to the phosphated OAT chemistry. Car makers specify one or the other, so go by the coolant type the handbook names rather than treating them as the same.
• Can I top up my existing coolant with it? Only if the system already holds the same silicated-phosphated type. When changing a car from one coolant type to another, drain and flush the system first rather than mixing the two.
• How should I mix it? Half concentrate and half deionised or distilled water gives the -37.5°C freeze point quoted at 50% dilution. A coolant tester confirms the result once it is in the car.

Which one?

For makers that specify phosphated OAT without silicates, NAPA Ultra LL P-Oat (N91520L) or Exopro Ultra LL P-OAT (U915D20L); for a top-up only, NAPA Longlife Universal (N91320L).
