Fluid Replacement Guide

Our cars are machines. Those machines are dependent on the fluids we put in it. Oftentimes, we neglect to check or change fluids when needed. On average, our cars have 9 different types of fluid that is required for our cars to continue running at its optimal output. I’ve put together a handy guide as a reminder to check these fluids. These are all averages, not every car is the same, so be sure and check your owner’s manual for specifics regarding your vehicle. If you cannot find your owner’s manual, I have found a resource that will allow you to download it for free! So now you have no reason not to! 2 out of every 3 cars operate in “severe service” conditions that makes the fluids work harder than normal. Examples of severe service conditions include lots of short trips, stop-and-go driving, hauling heavy loads, operating in extreme temperatures (Yes, our Texas summers count as extreme), prolonged idling or driving in dusty conditions. These severe driving conditions make the need for checking our fluids more important than ever for getting the most out of your car.

Common Questions: What Does The “2” & “L” Mean?

Being in the car repair business, we field questions regarding the ins and outs of your vehicle on a daily basis. One that I get on a consistent basis asks what the different settings are for your automatic transmission. Everyone knows the P (park), R (reverse), N (neutral), and D (drive). But what are the other numbers and letters? Here’s a rundown and how/why they should be used.



This number denotes that when you are in this position, your car will not cycle out of 3rd gear. You’re probably asking yourself why you wouldn’t want to get out of 3rd gear, but there are situations that warrant it. You would use “3” if you were stuck in sand or snow (more power to wheels, less speed).



This number tells you that your vehicle will not cycle out of 2nd gear. You would use “2” if you were pulling a trailer up a hill (more pulling power, but less speed than 3).



You would use L or LOW basically when you need power to the wheels, like pulling a heavy trailer, driving on ice, or any situation when traction is of the utmost importance…


But remember, don’t drive in any of these lower gears for an extended period of time or at high speeds, these settings are situational.
