If you drive your car in extreme hot climates than you should read this article. When your car is exposed to hot climate weather on a regular basis it will cause your oil to break down which then results in engine and sludge deposits. Hot temperatures will also cause your oil to thin out which results in metal to metal grinding in your engine. This problem can escalate even further if you are constantly towing heavy loads in hot weather. To avoid this problem it is always best to run a higher viscosity oil. There are several oils on the market that will meet this demand.
Another driving condition that can be harmful to your motor oil is only driving short distances each day. Your car never reaches its normal operating temperature which creates water condensation in the motor diluting the oil and breaking it down. This will shorten the engines lifespan leaving you with a costly repair bill.
We have talked about extreme heat conditions to your oil so what about extreme cold conditions. If you live where the outside temperature is cold the oil in your car will run thicker which makes the oil harder to circulate in the motor when you go to start it. This makes it harder for the engine to start up and will lead to faster engine wear. So in cold weather it is always best to run a thinner oil viscosity to avoid these problems. As outside temperatures change during the season it will be important to change your oil to the correct viscosity.
