Optima D5 is formulated using a robust additive package and hydro-treated base oil to deliver real performance in
today’s heavy-duty diesel engines, especially those fitted with modern features like Super-charger, Turbo-charger and
multi-valves drive trains.
Optima D5 is a proven choice with the transportation industry in Asian region. It minimizes high temperature carbon deposits,
which is by far the most concerned issue for today’s heavily loaded modern diesel engines. The reduced carbon build-up means
less rings wear and cylinder bore polishing resulting in much reduced diesel consumption, less ring breakage and piston skirt
scuffing. Its high ability to neutralize acidic by-products from the diesel combustion ensures minimum corrosion of the engine
parts throughout the lengthy oil drain interval.
