Shell Oil Company is offering a free eight-page booklet on questions and answers about MVI (medium viscosity index) oils used in medium-speed diesels.
The booklet compares performance of MVI oils with high viscosity index (HVI) oils in the large medium-speed diesels typically used in shallow draft marine vessels and offshore drilling rigs.
It defines MVI, HVI and LVI oils, tells how the viscosity index is determined, and describes the effect of VI on engine performance. Other areas covered are the effects of modern technology on lube oils, engine oil monitoring, engine manufacturers' lube oil recommendations, and supply and demand.
