GM Dexron III H
Oils approved by Opel, General Motors GM Dexron III H
The Dexron III License H approval was introduced in 2003 to replace the Dexron III G approval fluids. These oils use an oxidation-stable base oil (group 2 or 3).
Oils within this tolerance retain their friction-reducing and vibration-preventing qualities longer, better control foaming and have an increased service life
