Performance Profile
- Far exceeds: the requirements of:
- API: SL, CF
- ACEA: A3 / B4
Description
Competition fully synthetic engine oil. Formulated with 100% synthetic base fluids, including a synergistic blend of three esters combined with the latest additive technology for maximum performance.
Application
Use for competition or modified engines where maximum power release is the preferred criteria. Formulated for high revving engines used in circuit racing or for larger engines for short duration i.e. hill climbs and sprints.
User Benefits
- Fully synthetic oils provide many outstanding performance benefits over conventional mineral oil
- By utilising both polyalphaolefins (PAO) and ester synthetics specially selected to minimise the amount of polymer used, the lubricant film provided is more resistant to 'shear' and viscosity loss in high stress areas
- Load carrying capacity many times that of mineral oil. High film strength for ultimate protection. Outstanding cold flow properties for reduced wear at start up. Excellent thermal stability and oxidation resistance. Suitable for operating at 125°C with peak temperatures up to 150oC.
- Provides the optimum balance between hydrodynamic and boundary lubrication and the power absorbed through pumping losses to ensure maximum power release

Perfect grouping of toys for puppies
I have four eight week old Frenchie puppies and they definitely need some toys to play with and chew on. These are absolutely perfect. They're the right size for their little mouths and they have squeaks and little crinkles and all kinds of noises to keep them interested in the toys for quite a nice period of time. The price is excellent. And the size is perfect for them. It's a great value and if you're looking for something to occupy a puppy you can't go wrong with this

Skye's Absolute Favorite Ball! 🐾
Size: 1 Pack, Style: Ball
Hello, I am Skye! I am an Australian Mountain Doodle puppy, and my humans finally found a ball that can keep up with me! The Benebone Natural Rubber Dog Ball is officially my prized possession.
Why I give it five paws:
The Perfect Chew: It is made of natural rubber, which means it has this amazing, springy texture that feels so good on my teeth. It's super tough, but it still has a satisfying squish when I chomp down on it.
Funky Bounces: Because of the rubber and the design, it doesn't just roll in a boring straight line. When it hits the floor, it bounces all over the place in crazy directions, which makes chasing it so exciting.
Easy to Carry: The texture makes it really easy for me to grab with my paws and hold onto in my mouth, even when it gets a little slobbery during a long game of fetch.

So far this is the perfect alternative to other wobble toy feeders. Please make a bigger size!
Size: 1 Pack, Style: Pawbler
Why did you pick this product vs others?:
I bought the Pawbler because the two most popular wobble treat feeders on the market are plastic, and one of my dogs just absolutely destroys those in no time because he bites them and throws them rather then nudging them and then he has plastic cutting him so I am forced to throw away a costly treat toy/dispenser. I thought maybe a rubber one would work out better. So far my dogs love it, it works well spitting out their kibble, seems to be holding up and is easy to clean and feels like a good weight, not a super flimsy toy.
I would love to see it made in a slightly larger size, I think this current size is good for medium dogs. It holds just under a cup of small round kibble but I would like to see one that can hold more and is slightly larger in size.
I have 4 german shorthaired pointers, my test subject for this toy is mostly my 70 pounder who bites the toys instead of nudging them and throws them across the room, so it is taking a beating. I think for him a larger size would be helpful in deterring that behavior but I also think this may be too small for larger breeds.
Durability:
So far this toy looks just like when I bought it. It has no punctures or scratches and unscrews without problem. We have only had it a week or so but we use puzzle/toy feeders to feed our dogs lunch every day so it is pretty easy to tell which toys won't last long. Obviously, I can't speak to long-term durability at the moment, but I can say that most toys similar to this end up already scratched or punctured in a few days, so this is already sturdier when compared to what I have tried before.

Well made and durable, not a toy the pups seek out
Size: 1 Pack, Style: Tug
Well made. Thought our staffies would love since they live tugging with each other. Sadly not something they seek out. We love ALL the benebone chews though!

Durable fun enrichment toy
Size: 1 Pack, Style: Pawbler
I had been wanting to buy one of these kinds of toys for some time but thought that the other brands I had seen were too pricey so this was a great compromise for the price. My 5 yr old Portuguese water dog loves it. He spent 25 min playing with it the first day. The trick is to find a treat that is just big enough where it doesn’t fall out right away so it makes it challenging and fun for them. He has been chewing on it a lot for a week and it has not broken or shown signs of damage. One thing to note is that there is a small hole on the bottom of the toy so you cannot freeze liquids in it without covering the hole in some way so that would be my only complaint. Besides that it’s a great toy that keeps him busy and happy.
