Function of this part
The engine control module (ECM) is the electronic brain of the engine. It reads information from sensors and commands fuel delivery, timing, and other actuators to keep the engine running properly.

Quality. Price
Size: 20.3 Fl Oz (Pack of 3)
I have bought this lotion alot I the past. But this is the best price I have got. It is the main reason for my purchase other than I liked the lotion. If you have never tried this lotion then dont hesitate, its pretty good stuff. I recently I have became more conscious of the ingrediants on lotions so I switched. But I wouldn't hesitate to use this. Save some money and time and buy it here if you are already a regular user. And if you looking to try it out I wouldn't hesitate unless you are ingrediants conscious. It definitely moisturizes the skin untill your next shower. Feels good. Not greasy. Apply for any sort of dry skin. And it smells good if that's one of your requirements.

Love This Product on My Skin. Buy the 3-Pack for Epic Savings
Size: 20.3 Fl Oz (Pack of 3)
I always recommend checking Amazon for three-packs, family packs, or value bundles of products you use all the time, because that’s usually where you start seeing real savings. Everyday household products can get expensive when you’re constantly buying single bottles at grocery stores, so finding a good bulk deal really does make a difference over time.
That’s especially true with a quality product like Vaseline Cocoa Radiant Body Lotion. It’s a great moisturizer, works well for sensitive skin like mine, and leaves your skin feeling soft without feeling overly greasy. The scent is phenomenal too, which makes it something you actually enjoy using regularly instead of just treating like another basic lotion.
What I also like about this three-pack is that the bottles are lightweight and easy to handle. They’re convenient enough to take on an overnight trip or keep stored neatly in the bathroom without taking up too much room. And because you’re getting multiple bottles at once, you don’t feel like you’re constantly running back to the store every couple of weeks.
If you actually compare prices and pay attention to sales, you’ll notice these bundles on Amazon can end up being significantly cheaper than buying individual bottles locally at a grocery or department store. The value is definitely there with the three-count package, especially for a name-brand product that consistently works well.
Highly recommended if this is already a product you use regularly.

Highly hydrating and non-greasy
Size: 20.3 Fl Oz (Pack of 3)
I’ve been using Vaseline Intensive Care Cocoa Radiant Body Lotion for quite some time, and it’s easily one of the best lotions for daily use. It absorbs quickly into the skin without leaving that heavy, greasy residue behind, which is a huge plus when I’m getting ready in the morning.
The cocoa butter scent is subtle and pleasant—not overpowering—and it does a fantastic job of keeping skin hydrated throughout the day, even in drier climates. Having the 3-count pack is super convenient, as it ensures I’m stocked up for a while. It’s a reliable, high-quality moisturizer that consistently delivers on its promise of a healthy, radiant glow.

Good lotion
Size: 20.3 Fl Oz (Pack of 3)
Vaseline intensive care just makes really good lotion. I’ve never been steered wrong by them. And getting these on clearance was so good. I’m still on my first bottle, but I don’t put it on every day. Maybe twice a week. So the bottle has lasted seven months so far and there’s still a quarter of the bottle left. That means I have at least two years worth of lotion for $10. Can’t beat that. And it’s a good lotion to boot. The fragrance isn’t too strong. It absorbs really quickly and keeps your skin soft. The pump works great. I haven’t gotten any clogs or anything yet. Though, I usually don’t have those if I’m using it as often as I have been. Highly recommend would buy again… in a couple years.

Decent lotion, good for not so dry climate.
Size: 20.3 Fl Oz (Pack of 3), Size: 20.3 Fl Oz (Pack of 3)
This lotion smells amazing. I usually don’t go for scented lotion but I’m a sucker for sweet chocolate-y scents. This lotion smells like brownies. It’s not particularly mild so make sure you’re okay with it.
It’s not a thick lotion in my book, has a yogurt consistency. You can feel the moisturizing effect as soon as you put this lotion on. It is a comforting lotion without being sticky or heavy, easy to absorb into skin.
Although very nice and comfortable feeling when putting on, it doesn’t last through the next day in Colorado winter. I have to use it one more time on my legs during the day otherwise I get itchy. I apply this lotion at night after shower and I don’t shower put lotion on the next morning. If you do shower and lotion up in the morning then this might be good enough for a whole day. I’m used to applying lotions on damp skin but this lotion is very easy to spread, feels nice going on my dry legs as well.
I love using it after washing my hands. I apply lotion every time I wash my hands and this lotion works great in that regard. It doesn’t feel greasy or particularly slippery when I wash my hands again either.
I might try another lotion for winter once I finish these bottles but this is definitely a solid product, and I can see myself repurchasing in the future.
