Recently, my newish Nissan Pathfinder has been getting less than it’s previously stellar 24 mpg. When I was asked to participate in a shopper study with STP, I literally jumped at the chance to find out if this stuff works. I know people who use it reguarly, and swear by it. But I’ve always been hesitant to buy some and stick it in my tank.
First of all, I’m not a car guy. Key, ignition, oil change every 3,000 miles. That sentence sums up the majority of my vehicular knowledge.
I mostly use premium gas, and I’ve never really understood when and where I would know it’s time to use an engine treatment. Is there a sound? Will a light come on and say, “I need a little something extra today?” It never happened. But as I’ve watched my mpg dwindle recently, I’ve been thinking about what my engine might need BESIDES that oil change, that I haven’t been giving it.
But logic prevailed. My logic… which stated that I have no idea what most of these things do . . . and unless directed otherwise, I should probably get something that will treat and help multiple parts of my engine, instead of just the fuel injectors.I went to Walmart seeking out STP Treatment. I figured there was just one. Wow. There were tons! Different little bottles for cleaning all kinds of different things! I was drawn to the fancier bottle designs, and almost ran away with the one below.
The STP Multipurpose Motor Treatment seemed to do everything I could want:
- Cleans Fuel Injectors
- Cleans intake valves
- stabilize fuel and oil (no idea what that means)
- Remove Moisture
- other things that I don’t understand
The product is easy to use, but I wavered awhile on exactly how much to put in the tank. I have a 16 gallon tank, which was half full. Do I put in enough for a full tank, or enough for the current amount of gasoline? I just started pouring, and stopped with about half of the bottle empty. I stared at my car and kept thinking there should be something else for me to do. But nope – that’s all I needed!
I have another older Sunfire, so I put the rest in there. I had to pick up some Transmission Fluid for that car as well, since it’s been leaking some. Hopefully between the two new products, I can get a little more life out of it!
Tomorrow, I head out on a 5 hr road trip. I’m really looking forward to seeing how STP impacts my engine’s performance. I’ll update this post with my thoughts afterward!

Also, if you’re interested, STP is offering a coupon if you like their Facebook Page! You should definitely check it out!
UPDATE: After a total of nearly 12 hours on the road in the last 2 days, my MPG has gone from 18.7 back up to its previous average of 23.4! I’ll definitely be picking up STP again!
