Let’s discuss Fluids Maintenance:

There are three important fluids to maintain and they should not be neglected.
Engine Oil: It is crucial to pay attention to engine oil. Very old oil or lack of oil can completely ruin your engine. Engine problems are some of the most expensive to repair, but regular oil changes can make the difference. The rule of thumb is to have your oil changed every three months or three thousand miles—whichever comes first. Remember that oil can oxidize over time and should be changed regardless of the mileage. Check the oil levels in your vehicle frequently. If it drops by a quart or two in a relatively short period of time, you may have a leak. Always check your vehicle’s owner’s manual that will give you specific details about the frequency and type of oil specifically required for your make and model vehicle. Keep in mind that the types of driving you do the majority of the time will determine the frequency of oil changes.

Transmission Fluids: Your vehicle’s owner’s manual will give you details on the specific transmission services required for your car. What the manuals don’t always recommend is a complete fluid flush that replaces all the fluid in the transmission. This is a service that I strongly advise having performed (every 30,000 miles of city driving or 60,000 miles of highway driving) regardless of what the fluid looks like on the transmission dip stick. Many times while performing a flush, I have seen that the fluid on the dip stick is red (normal color) but it actually comes out black from the machine when drained. Don’t judge a stick by its color!

Differential Fluid: Check your owner’s manual to find out if your vehicle has a differential. Four wheel drive trucks commonly have two including a transfer case. The fluids inside a differential can break down depending on city, highway and towing conditions. Your owner’s manual will provide guidelines as to regular maintenance of these fluids.

Fluid maintenance is detrimental to the upkeep of your vehicle’s engine and its overall operation. Know your vehicle. Read the owner’s manual and don’t procrastinate taking your vehicle in for regular fluid services.
