5-30W Synthetic Motor Oil

Great product and price. I go thru 5 gallons pretty fast as we do a lot of miles between 2 cars. Only complaint is the nozzle pulls straight out and makes it difficult to pour. a 90 degree spout would be nice.

It worX

I have an old XJ with 80k miles on it. The XJ has a Toyota transmission and they are know to slip a little when not serviced. I could tell mine had a slight down hill slip when towing. I picked up 15 qts of this and ran it through for a good flush.
The next week I took my trailer on a 300 mile trip and this didn’t miss a beat and the vehicle stayed cooler. I would recommend this to anyone needing fluid. It works and the bottle is nice with the pour top.

Came fast but one bottle leaked

Good service, oil arrived quickly but one of the gallons had leaked :(

oils

Excelent shipping packaging and quick delivery considering the miles travelled, My first time using Triax products and so far happy with the decision

Great Oil Shipped to Your Door.

I use this oil in my Powerstroke trucks and my tractors. It is so convenient to have the same oil for all those applications. The oil has preformed flawlessly and is reasonably priced and shipped fast.

Grease works well on my loaders and tractors.

I have several tractors and so far the grease seems to work well. Seems pretty tacky. And on sale is very comparable to cheap grease, so why take a chance?

I'm not so good on this one.
It's like black shoe polish.I think it's great for tire detail. The trim is little messy even with sponge applicator.Plus the trim need to be cool to apply.I differently would applie in garage or shaded area. Look geat on tires. Need to apply trim again when sun goes down to element streaking. Also wear rubber gloves so your hands are not covered in black. But for the product it self it does what it says.Keep the trim Rich Black!

It meet the Case specs

Been using it in my Case 95. Time will tell on wear. So far it works great.

Great quality product for the money.Clean finish after rain storm+work great on plastic panels and bumpers.Best shine hands down.Great on chrome Rims and no water spots on the vehicle the more use the better the protection, also can clean glass windows. 7 stars product ⭐⭐⭐⭐⭐⭐⭐

Great product
