Detergent dispersants and anti-wear agents break up sludge. Four-point depressants maintain fluidity in cold climate conditions. Viscosity index improvers stabilize viscosity levels over a range of operating temperatures. Defoamants maintain proper application of oil on cylinder walls. Oxidation inhibitors resist creation of oxidants which increase viscosity levels and decrease fluidity.
All grades meet API standard specifications.
Please consult your Owner's Manual for the proper grades for your Toyota.
