I used this product to change the differential oil in my Tacoma overall, good price compared to some of the competition. I would buy again.

High Quality Oils
I've only recently discovered Triax oils. I first started using them in my lawn mowers. These machines are constantly running throughout the spring, summer, and fall months. I need an oil that keeps up with the demand of these units to run smoothly, with limited downtime. Triax Synergy has kept them operating at a high level. I've since switched to using this brand in my other vehicles. The gear and motor oil are exceptional products.

Good quality 75-90 synthetic gear oil, LS formula, works well.
Triax makes good lubricants based on what Ive heard and experienced. It meets all the specs for my Dana 60 front axle in my 2000 F-350. It says it's limited slip ready, but I still added some friction modifier. I used it in my last diff oil change and after 6 months of driving around, the axle is still running nice smoothly.

OIL GOOD, JUG MEH
Ample positive reviews, made in USA, seems like good oil. My only gripe is that the gallon jug comes with a cap that cannot be entirely removed. Instead there is an inner cap that pops up to expose a small pour spout. It’s no longer than an inch or so. This may help prevent oil from dripping down the side of the jug after pouring the product. Fair enough. Problem is, being that this is gear oil, most people will need to attach a pump in order to refill differentials and transfer cases. You can’t just pour gear oil into those. I had just bought a fluid pump and this oil to replace the rear differential oil in my tundra. The pump I bought was designed to screw onto a gallon jug. No can do. I was able to slide the pump into the pop-up spout about a quarter inch but the longest tube that came with the pump was not nearly long enough to reach the bottom of the jug. Luckily I had some tubing that fit over the pump tube that reached to the bottom of the gear oil jug. Sure would be nice if the entire cap was removable. It would make the process easier. The pop up spout can be left on there if you think the market needs it but please make the entire cap removable. Lastly, this oil is crystal clear. I’m neither here nor there about this as I am not a chemical engineer. It’s just extremely unusual to see gear oil being clear.
