Sometimes you'll use our Find Your Model tool to choose your vehicle and you get recommended something that looks like this:
The reason an adapter gets recommended is usually because we've been warned that the vehicle in question has a recessed oil drain port, which means the drain port itself is not flush against the wall of the oil pan. It can look a little like this:
When your oil drain port is recessed, installing most Fumoto valves becomes impossible because the head of the valve will hit the part of the pan that sticks out further than the drain port. This is where adapters come into play.
Using an adapter allows you to offset the head of the valve so that you can install the valve and fully rotate it without it hitting the pan wall or lip, which leaves you, and us, kind of frustrated.
When does the SX valve help me avoid this?
SX valves can help you avoid adapters, but only when the valve can be pointed away from the ground. In the photo immediately above, an SX valve would be an easy install that would avoid the need for an adapter because the valve body can be pointed away from the ground and toward the passenger side of the vehicle. The one above is on an Acura RDX.
A good install for an SX in a recess might look like this:
Some other recesses simply require adapters in all situations because the shape of the recess doesn't allow you to point the valve away from the ground:
In an instance like this, if you choose to go with the SX style, you'll also want to couple it with an adapter extension (ADP or ADL adapters) to be able to rotate the valve away from the ground.
You suggest two different adapters. Which one should I choose?
With some Honda's, you'll use our Find Your Model tool to search for your vehicle and you'll get suggested two different adapters. The decision on which one to choose (since we don't get to physically inspect the drain ports of every one of the thousands of cars we fit for) is yours, since you can physically see what's going on under there.
The reason for this is, well, Honda has some stuff going on around their drain ports. Some look like this and require the long (ADL) adapter to install our 1st gen valves, but will install an SX valve without the use of an adapter:
If the recess is not as deep as the photo above, then you might be able to get away with the shorter (ADP) adapter to install one of our valves.
While others have obstructions on the right side of the drain port, like this:
When the drain port looks like this, no adapter we offer will help you install one of our valves. The only solution is to install an SX valve upside down (See picture below).
IMPORTANT NOTE: Please check to see if the valve is positioned too low to the ground. If it is too low, please use an adapter to push the valve away from the recession and position the valve away from the ground. Please use our product safely. Make sure that your valve is installed in a safe place. Do not install the valve if it is exposed and hang down too close to the ground.
