Lube to avoid these three prob­lems

The Witness - Wheels - - MOTORING -

AT the Bauma Con­struc­tion Expo held in Gaut­eng last week, Ger­man lu­bri­ca­tor Liqui Moly demon­strated how to sim­plify ve­hi­cle and ma­chine main­te­nance and ex­tend main­te­nance in­ter­vals by sim­ply us­ing the right lube.

“Less down­time means more pro­duc­tiv­ity and fewer costs,” ex­plained Roland Sch­midt, who is in charge of the Con­struc­tion and In­dus­try di­vi­sion at Liqui Moly Ger­many.

He listed five prob­lems that also af­fects cars and demon­strated how pre­ven­tive main­te­nance quickly saves op­er­a­tors and driv­ers money.

Dust in the mo­tor oil

There’s no way to keep dust from get­ting into the mo­tor oil when run­ning en­gines in a dusty en­vi­ron­ment.

This sig­nif­i­cantly in­creases wear in the en­gine. The more dust ac­cu­mu­lates in the mo­tor oil over time, the worse the wear be­comes.

Add a clean­ing ad­di­tive to the en­gine be­fore an oil change so that the ac­tive in­gre­di­ents can float the dust par­ti­cles in the oil, al­low­ing it to be drained off be­fore fresh oil is added.

High sul­fur diesel fuel

This cre­ates sul­fu­ric acid dur­ing the com­bus­tion process in the en­gine.

That’s why en­gine oils in­clude ad­di­tives which neu­tralise sul­fu­ric acid prod­ucts, so that they can­not do any harm. But the neu­tral­is­ing ca­pa­bil­ity is lim­ited. Once the ad­di­tives are de­pleted, en­gine cor­ro­sion will oc­cur.

Those who want to be on the safe side change the oil at shorter in­ter­vals — or use ded­i­cated mo­tor oils that of­fer a higher acid pro­tec­tion and can sig­nif­i­cantly ex­tend oil change in­ter­vals.

Con­tam­i­nated in­jec­tors

Minute par­ti­cles get stuck in the in­jec­tors’ noz­zles over time.

These pre­vent the in­jec­tors from atom­is­ing the diesel fuel into a fine spray. An ir­reg­u­lar spray­ing pat­tern has an im­me­di­ate ef­fect on the en­gine per­for­mance.

Power and torque are re­duced and fuel con­sump­tion in­creases. Poor diesel fuel qual­ity makes all of this even worse.

Sev­eral con­cen­trated ad­di­tives are sold that can be added to the ve­hi­cle fuel tank to re­move harm­ful de­posits, pro­tect the fuel sys­tem from cor­ro­sion and in­crease the life cy­cle of the in­jec­tors.

As Wheels has warned, not all work equally well, but Liqui Moly backs its ad­di­tives with more than 50 years’ ex­pe­ri­ence and sales in 110 coun­tries.
