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!
