Summer Weather – The Enemy of Your Tires?

August 18th, 2015
Tires in Baton Rouge, LALet’s talk for a moment about tire pressure. 
 
Every tire flexes a little at the bottom, as the weight of the vehicle bears down on it. The section that is subject to that weight and flexing changes constantly as the tire rotates, and the average tire rotates 750 times over the course of a mile. At 60 mph, that means the tire rotates 750 times per minute. All that flexing and deformation means heat buildup, and increases tire pressure by roughly four pounds per square inch (PSI). After an hour or so on the road, a tire is about 50 degrees hotter than ambient air…but that temperature differential is even greater in hot weather, especially since pavement is hotter than ambient air. Heavier loads and higher speeds will add to that heat buildup.

Why Is Quality Motor Oil So Important?

August 8th, 2015

Oil Changes in Lafayette, LAConsider for a moment what’s required of your motor oil. It has to provide a film of lubrication between metal parts, so that they can freely move against each other without friction, overheating or damage. It has to trap the carbon byproducts of combustion and suspend them so they can be trapped by the paper element in your oil filter. It has to neutralize the acids that are produced during the combustion process. It also has to reduce heat in parts of the engine that aren’t surrounded by a water jacket for cooling. It can’t get too thick in the winter, which would make it hard to circulate on a cold day, but it can’t thin out too much in the summer either. That’s a lot to ask of one substance!

Older motor oils didn’t include additives like detergents and other modifiers that ...[more]
