WIDMAN INTERNATIONAL S.R.L. was founded in 1996 in Santa Cruz, Bolivia with the mission of increasing the level of quality of lubricants available to the Bolivian market, increasing the life of the vehicles and the industrial equipment.

Today WIDMAN INTERNATIONAL has distribution centers throughout Bolivia.

With the direct importation of AMERICAN lubricants from the United States, WIDMAN INTERNATIONAL S.R.L. has made available to Bolivia the for the first time lubricants of the highest technology in the world.  These products are far superior to those made locally or currently imported from other countries.

All of our oils are formulated with the highest quality base stocks available and the most advanced additive packages available worldwide.

Contrary to the majority of the brands in the Bolivian market, WIDMAN INTERNATIONAL does not offer inferior or obsolete products. We are guided by the API and other world agencies, presenting to the Bolivian consumer only the best possible products, eliminating the possibility of error when choosing oil for his or her vehicle or equipment.

We do not sell motor oil for gasoline engines that is less than API SL, nor diesel engine oil that is less than CI-4 (monogrades CF-2, CF-4).

Our gear oil protects against the extremes of Bolivian roads with 50% to 87% more resistance to extreme pressure than the other GL-5 gear oils in the market.  We also stock synthetic automatic transmission fluid for Ford, Honda, Mitsubishi, Chrysler and other brands that require special ATF, and special manual transmission fluids for all of the various cars and trucks in the country.

All of our products are manufactured and packeged in the United States in drums and pails, then shipped in sealed containers to Santa Cruz where we distribute them throughout the country.

In October 2004 we launched the complete line of lubricants that use the American Petroleum Base Stock MAX-SYN®.  This advanced base stock puts the performance of American Petroleum products way above the rest of the products, giving performance in many aspects similar to traditional synthetics.

We specialize in personal recomendations and assistance to help each customer obtain the maximum possible yield from his equipment through optimized maintenance.

Our regular customers benefit from our Used Oil Analysis program, where we identify equipment problems as they arise, making recommendations for proactive maintenance that reduces down time and increases productivity.

In January 2003, Widman International opened its own Quick Lube facility at our offices in Santa Cruz.  Here we can guarantee rapid service and the best possible North American lubricants made.  Every vehicle is inspected by a qualified mechanic and recommendations made for the safety and interests of the customer.

In the time that our oil change facility has been open we have found hundreds of oil filters that were either incorrect or incorrectly installed and many air filters that had been rendered useless by cleaning with high pressure air or installing incorrectly.

We have cut open and studied most of the oil filters available in the market and identified serious deficiencies in many, from non-sealing valves to outright forgeries.  Click here for details. (English)

The majority of this site is in Spanish.  Many of the pages in the Oil Analysis section and some of the other pages have English commentary as well as Spanish.  If you are looking for specific information in English, please feel free to contact us.
