As of now I use this oil in my truck that gets very heavy use off road as well as Highways with 8% grades.
It withstands the AZ heat and high speeds up hills and daily use in cold and hot. The breakdown time is insane compared to my previous Amsoil or Shell oils.
6 months or 5k miles is my preference, and sometimes I question myself mid oil change because it still looks and feels good.
I run my Turbo hot and engine is very high in timing, so that I get higher mpg. After making the conversion to this oil my avg economy went up, from 18.7 to a steady 20.2 as well as the darn thing got quieter at idle and cruising.
All that with going 5k with no oil burn in the 24v is just awesome and it keeps my engine insides clean of sludge that was building up even with other oils.
I understand markets and whatnot fluctuate the oil prices, I do hope that Triax can do everything in their power to keep the lube flowing for us because I will likely use this oil for as long as I operate Trucks and engines!
Triax always delivers with their stuff! The correct weight gear lube from my front and rear diff at a great price!
Good quality product at a good price. I had to deduct a star because of the packaging. Normally, I like the pour spout on smaller bottles, but on this one it made things a lot harder using any of the available pumps to be able to fill my transfer case easily. Would still purchase again.
Can't really comment on this Triax 15W-40 destined for a friend's Ford PowerStroke pick up , his 70th BD gift. My prior oil reviews suggest great stuff. What I do want to mention is the transaction process..online Triax ordering over multiple orders has gone unusually smoothly each time, not always the case with other Online Retailers.
Order placed, shipped superquick via FedEx, tracking number right there on time , and Fedex link if you want to see their progress...5 star communications in all. If you order Triax via a "big box" online store (i.e. to save shipping if Triax site minimum not met) the inclusion of a middleman slows things down, 3-4 days longer to receive, not terrible but I'm spoiled with "ordered Thursday night, arriving Monday mid day" from TX to NC.
CVT fluid works well in 2017 CRV, but I noticed that the 5 quart bottles that had no leaks, and were still sealed from Triax, only had 4.5 qts inside each bottle. FYI. Case of (3) 5 qt bottles Purchased July 2025
Been using this in my Ford 6.7 for three years now. The engine runs quiet and smooth and no typewriter tick after oil changes.
Works as advertised. Easy to apply, do it on a day where you aren’t in full sun and scorching hot for best results. Another good product from Triax!
It sure is black i recommend waring gloves goes on easy it stays black only a few weeks as of now but still looks good
At 20,000 miles the front diff had a low pitched hum at lower rpms. Drained OEM 75W90 gear oil...was 375cc below fill amount. Replaced with Triax product ,corrected level with resolution of whine.
