TRIAX Synergy SRT 5W-30 - Full Synthetic, Friction Modified Engine Oil - 20K Miles, API SP Licensed, 3x Wear Protection - Nano Boron and Moly Friction Modified (1 Quart)

Wow! I'm impressed! Quieted down the engine noise and smoothed out the engine!I like how the spout is built into the jug too! Very convenient. A bit expensive but well worth the price.

I have one of those Kia Theta II loud rattling engines. This oil makes it run smooth & QUIET. Now, it’s all I’ll use.

Great oil for a great price. Put it in a 5.7 hemi and the hemi tick is gone. Definitely recommend this oil

Like another seems every engine it's in runs quieter than with other brands I've used. Just went through week of below zero morning temps no issues with starting and thus far seems to be running cleaner than other brands. If see any change in summer use will update.

Purchased this oil multiple times to run in all my gas engine vehicles. Convenient ordering. It did quiet the engine on start up on my Chevy Silverado.

Good oil

It’s a bit cheaper than the best synthetic but it’s good!!! Definitely worth a shot!

I was skeptical of this stuff, I mean who's heard of them before? A friend of mine that does oil testing for a living runs it, so I said if it's good enough for him, why not try it. Within 1200 miles I was getting better MPG (not stunning but a solid 2% improvement), the engine was running quieter and smoother than it had ever run, even new.It did turn dark quick which I was concerned about but it was explained by my friend that the oil was cleaning all the varnish and crap out of the engine. I ran it to 10k miles with a filter change at 5k miles.Turbocharged Volvo 5 cylinder didn't burn any off, 6 quarts went in, 6 came out. I can't argue with it. So another 6 quarts went in. The Blackstone report was amazing as well. No issues and plenty of TBN left (2.7 which tells me I could have gone to 12k or maybe 15k-which is crazy to me).I'm absolutely impressed, and will continue to run it.
