Description

TRIAX X-Terra 4T 20W-50 is a full synthetic motorcycle oil engineered specifically for high-output V-twin engines operating under sustained heat, heavy load, and high torque. It is designed to protect engines, transmissions, and wet clutches in demanding street, touring, and performance applications.

X-Terra 4T Synthetic oils provide exceptional thermal stability, shear resistance, and wear protection while helping control sludge, varnish, and high-temperature deposits. Its carefully balanced friction characteristics support strong clutch engagement, smooth shifting, and consistent drivetrain performance even under severe operating conditions.

Formulated to meet or exceed JASO MA2 and API SN performance requirements, TRIAX X-Terra 4T 20W-50 is ideal for V-twin motorcycles

Engineered for V-Twin Engines: Built for the extreme heat, high torque, and heavy-load conditions common in large-displacement V-twin motorcycles.
High-Temperature Stability: Resists oxidation, oil thickening, sludge, and varnish during sustained hot-weather riding, touring, traffic, and severe service.
Outstanding Shear Stability: Maintains viscosity under the severe mechanical stress created by high-torque engines and integrated transmissions.
Wet-Clutch Optimized: JASO MA2 friction characteristics support strong clutch engagement, reduced slip, and smooth, consistent shifting.
Advanced Wear Protection: Robust anti-wear chemistry helps protect cam lobes, bearings, gears, chains, and other highly loaded components.
Cleaner Running Engines: Strong detergent and dispersant chemistry helps keep critical internal components cleaner over extended service.
Smooth Transmission Performance: Helps maintain crisp gear changes and stable clutch feel under heat, load, and repeated acceleration.

Built for American and European V-Twins: Harley-Davidson, Indian, BMW, Triumph, and other motorcycles requiring SAE 20W-50 and compatible performance specifications.

Using in my Honda pressure washer all summer long.

Great oil in my pressure washer going strong all summer long

Just switched my Zero Turn mower hydraulic system to Triax 20w50 full synthetic. Only 10 hours of mowing since service. The mower is working well to this point.

Indian...

Been usuing this on my Indian Chief for a couple years now..doing a great job!!!

Outstanding Motor Oil

I started using Triax Lubricants XTerra 4T 10W40 and 20W50 a couple years ago and the operating results have been excellent. The 10W40 was used in my Honda ST1300 V-4 and my Can Am Spyder RT Limited 1330cc triple and the 20W50 in my Kawasaki Vulcan Voyager 1700 V-Twin. I noticed the biggest improvement in the Voyager. She usually runs a bit warm and shifting could be clunky at times. The biggest change in the Voyager was running cooler, I'm sure due to less friction, and much smoother shifting. The Spyder also has improved shifting in its semi-automatic transmission. In all the engines this motor oil smooths things out and allows the engines to run smoothly all day long regardless of outdoor temperature.

I've also used the Triax 0W30 in my Lexus ES350 3.5 liter V-6 with very similar results. It smooths out the engine and my MPG increases. These oils are true Group IV PAO synthetics and put up with a lot of heat without degradation in performance or engine protection.

As far as cost is concerned, it's not a concern. Purchasing a six quart case gets you free shipping and the unit cost for a quart is only $9.08. That less than most any other motorcycle specific oil most of which are Group III hydrocracked oils selling as "synthetic". So what I'm saying is here you get a real "synthetic" PAO oil to protect your engines at the same or lower cost than other popular motorcycle oils at a same or even lower cost.

I believe this oil is the real deal and I have had excellent results using it.

Happy Harley-Davidson Road Glide

I use this product in my 2017 Harley-Davidson Road Glide, and it performs well. It runs cooler and the engine just purrs.

Harley

I have purchased the 20w50 oil for my 2009 Harley Davidson xl 1200 custom Sportster, this oil is incredible my engine runs cooler and shifts better,this is the only motorcycle oil I will buy now

Rotella toTRIAX 5W40

So far so good Truck does sound Quieter mileage is better but haven't done any towing yet But with what l am seeing so far better than expected. Thanks
.

Seemed to smooth up shifts on our Duramax 2.8 6L50 transmission.

I just changed the transmission oil in my Duramax 3.0, and as in the 2.8 LWM, it smoothed out shift changes.

New ulv atf

The reviews of this product caused me to purchase it because they were all good

Stump grinder

Bought for stump grinder to provide exceptional protection and easier starts this winter. Great formula for equipment running at 100% every hour it is running

Ram 1500

Bought for rear differential service. Seems to be exceptional product with lower friction and less wear

Works great in my Kubota l3430 HST. No pump whine.

It works!

All indications are that my tractor likes this synthetic tractor hydraulic fluid. I also like that it is red so I can tell when the tractor is perfectly full.

ULV trans and GL5 diff fluids.

Recently switched both on my 2021 LM2 3 litre. Added PPE trans pan and ULV fluid, ran 5000 mi then drain and fill with 18 quarts switched. Will drain/fill trans pan in 30k. Trans working great at 150-160 deg with bypass valve. Recently purchased 0 - 20 and will switch from M1 mid Oct. So far, im happy about the quality at a reasonable cost. Future updates coming.

Seems to be great oil.

So far so good. Oil sample will give more details.
