I had one on my car before and made the oil changes really easy. I wound up removing it now since with the supercharger installed I can't reach the valve unless under the car anyways. A rock just missed it once and took some of the fins off the oil pan so I figured since I gotta go under there now anyways I would remove it.
But without the supercharger there it was awesome to be able to flick it open to drain oil!

 

If you're running a CAI or PRM intake you can change your oil without jacking up the car. I use a shop mirror to visually check the drain plug for leaks as a final step.

 

I usually do oil changes on a warm>hot motor for better oil evacuation but you can reach the drain plug from above if you want to, it only takes a couple minutes to jack up the car so why not.

 

i have it. great seller.

 

i always put my car on the lift to change oil so i can check on everything else. the valve would maybe save me 30 seconds. not worth it to me. if you don't ever look at your car to ensure everything is like it should be, then it would probably be a good time saver for you.

 

nice product but my oil changes are real easy, I don't think it would save me much time or effort. I raise the car with a jack, reach under and pull the drain bolt, lower the car over the oil drain pan, remove the oil filter from above, after it all drains out I raise it up again install the drain bolt and drop it for good, I do the filter install from above and I'm done. I don't use a jackstand as I never get my body under the car, I just reach under with my arm, no danger to cause harm. I let my car drain for quite a while so it's not about speedy changes for me.

 

After almost being crushed to death by my car falling off jack stands, I do whatever I can to reduce risk. The oil drain valve helps do that.

 

yeah I honestly hate going under the vehicle, when I do I go nuts with jackstands using up to 6 of them and even placing tires under the rockers. How did your car come off the stands ?

 

No danger? If the jack fails your definitely getting messed up bad. Unless you got some insanely long arms more than your arm is under the car lol.
Better safe than sorry.

 

My car fell off when the rear was up high on jack stands, and the front was not. I had been under the car installing an exhaust, then came out from under the car to work on the suspension. I tugged on a bolt, and the whole car slipped forward off the jack stands ... BOOOM!!!

The back wheels were off the car, so the chassis was just resting on the concrete where I was just laying minutes earlier. Wheel chocks don't work on the shiney slick concrete that is used in garages like mine, so I now make sure all 4 corners are lifted equally on jack stands, and also put ramps under a couple wheels as a backup.
