// Opera­tio­nal Fluids Testing

So Ever­ything Runs Smoothly!

Opera­ting fluids play a decisi­ve role in the deve­lo­p­ment of auto­mo­ti­ve technology.
// Fuel testing
Maxi­mum effi­ci­en­cy, mini­mum emis­si­ons and highest perfor­mance: these are the deman­ds placed on modern systems. They can only be met by using high-quali­ty engi­ne lubri­cants and fuels. Accep­t­ance by manu­fac­tu­rers is growing, and fuels and oils are being inte­gra­ted into the deve­lo­p­ment process. Their diver­si­ty is consi­derable — depen­ding on the requi­re­ments and inten­ded use, a wide varie­ty of products are offe­red and used. For all products, we provi­de the corre­spon­ding perfor­mance certificate.

The area “Fuels and Lubri­cant Testing” was APL’s first busi­ness area. It was the focus as the compa­ny foun­ded in 1989. From the very begin­ning, deve­lo­p­ment and imple­men­ta­ti­on of reli­able analy­ti­cal and engi­ne testing methods was actively suppor­ted. This contri­bu­t­ed decisi­ve­ly to the estab­lish­ment of a stable quali­fi­ca­ti­on system for opera­ting materials.

Engi­ne Oils

A wide range of engi­ne oils are tested and certi­fied here.


Fuel testing is part of opera­ting mate­ri­als testing and is one of the core compe­ten­ci­es of APL.


Here you will find the wide range of capa­bi­li­ties in the field of rating of opera­ting mate­ri­als and components.

Labo­ra­to­ry Analytics

APL’s labo­ra­to­ry analy­sis covers ever­ything from lubri­cant to fuel analy­sis and more.
