Racing Grade is a racing engine oil made from synthetic base oil with a special formulation, intended for race cars and severe driving. It is offered in 10W60 and 5W60.
Grades & published data
Typical values from the product data sheet, each with its test method.
Overview
Racing Grade is a racing engine oil made from synthetic base oil with a special formulation, intended for race cars and severe driving. It is offered in 10W60 and 5W60.
The 60 hot grade is the heaviest class in SAE J300, chosen for engines that run at sustained high temperature and load. Published values include viscosity indices of 185 and 183; the kinematic viscosity entries for these grades are still under technical review and are not yet shown.
Application
Competition engines whose builder specifies a 60 hot grade.
Application
High-load, high-temperature road use where the manufacturer allows a 60 grade.
Feature
Made from synthetic base oil with a dedicated racing formulation, as stated in the source documentation.
Feature
5W60: VI 183, TBN 10.5, pour point -45 °C; 10W60: VI 185, TBN 10.5, pour point -42 °C.
Only if the vehicle handbook allows it. Most modern road engines specify lower-viscosity grades, and a heavier oil than specified can slow oil flow at start-up.
Next step
The range above is what we publish. Formulation to a customer brief is a route of its own, and a sample is the first stage of it.
