Jim’s Word – October 2014: Friction, Lubrication and inertia

All moving parts of your car are subject to wear and tear. All of them will eventually need replacing. That’s just physics. Moving parts cause friction and friction will gradually wear out every part.

While we can’t change the eventual outcome, we can greatly increase the amount of time the moving parts last, which brings me to my next point – lubrication.

Regular engine oil changes are a must but there’s more to it than that. The quality of oil used is also of great importance. Good quality, correct grade oil will keep its viscosity under high-stress conditions meaning it will not only last longer but also protect your engine more effectively than a cheap, one-spec-fits-all lubricant.

Of course there are parts of your car that actually need to create as much friction as possible – brakes.

In this scenario the best way to ensure the longevity and effectiveness of components is to use quality pads, rotors, brake fluid and brake lines.

Good brake pads provide maximum grip without sacrificing the pedal feel. Quality rotors ensure the heat generated while braking is dissipated quickly – preventing the dreaded brake fade. Likewise, good quality, braided brake lines will not bulge and are less likely to leak under pressure.

This is one of the reasons why I insist we only use top brands who test and guarantee the performance of their products on all the cars we service.

They might cost a little more but the benefits far outweigh the difference in price.

Until next time, happy motoring!
