  • High zinc, good for older motors
Size: 1 Gallon
Used in my 78' Chevy 350. Good stuff plenty of moly, zinc, and boron. Good for an older flat tappet, pushrod engine. Full synthetic also a plus. The price is ok. It was at $22 for a gallon a few months ago.

  • Works Great in My Kubota
My Kubota MX5000 tractor likes this oil very much. It runs smoothly and starts very quickly. Next up, I will be using it in an Isuzu diesel-powered generator. Great stuff.

  • Economic and high value
Size: 1 Gallon
This oil works fantastic well in my Cummins 5.9. engine runs smoother less noise, I'm over 250k, so engine is making more noise than when new. Triax oil seems to be a very good oil for the money, especially with prices going through the roof. I hope this remains available for purchase long into the future. ... show more
