TUN­ING YOU STRAIGHT: Use or abuse

THE FINE PRINT IN ALL WAR­RANTIES WARNS THAT DRIVER ABUSE OF PARTS WILL VOID THE COVER. BUT WHAT IS DRIVER ABUSE?

JENS Denk of Denk’s Mo­tors in May Street in Pi­eter­mar­itzburg an­swers:

Abuse is us­ing some­thing in a way that it was not de­signed for. “Rid­ing the clutch” to hold a ve­hi­cle in place against an in­cline at an in­ter­sec­tion — in­stead of us­ing the hand­brake — is a clas­sic ex­am­ple.

Us­ing a lower grade fuel or oil is another. Oil is to a car what blood is to a hu­man body. It as­sists with heat­ing and cool­ing, it car­ries con­tam­i­nants away to the fil­ter, it lu­bri­cates and pre­vents cor­ro­sion and it helps with ab­sorb­ing noise. If your oil breaks down un­der load, it will not be able to con­tinue pro­tect­ing your en­gine from wear.

Oil is blended to give the de­sired base oil to add the vis­cos­ity mod­i­fiers, emul­si­fiers, anti-foam­ing and all the other ad­di­tives that make the oil do what the specs say it can do. As with with most things th­ese ad­di­tives have a life ex­pectancy, so its ex­tremely im­por­tant to change the oil and fil­ter in your ve­hi­cle at the right in­ter­vals, bear­ing in mind that how the ve­hi­cle is used will ei­ther shorten or lengthen that in­ter­val.

Another ques­tion we of­ten get that amounts to abuse is: “Can I leave the torn CV boots un­til the next ser­vice?”

Yes, you can drive the ve­hi­cle for another year while wa­ter and dust get into your CVs and grind them beyond re­pair so you’ll have to re­place them.

In my opin­ion you should bud­get the same for ser­vic­ing and re­pairs as you do for fuel and tyres, es­pe­cially if your car has done over 150 000 km.
