Questions
What is the difference between Group I and Group II base oil?
Under API 1509, Group II has at least 90 % saturates and no more than 0.03 % sulphur. Group I is below 90 % saturates or above 0.03 % sulphur. Both have a viscosity index between 80 and 120.
Do you supply finished lubricants as well as base oil?
Yes. Tell us the product type and performance level (for example the API service category) and we quote.
