Definitely noticed a differnece in how quickly our cars warm up. I think some people think it will get to full operating temperature in 30 seconds, which is ludacris. My truck get to operating tempature a few minutes quicker no doubt.
Bottom Line
Yes, I would recommend this to a friend.

not installed yet weighting for Whipple will report asap
Great stuff helps the engine build heat faster in the cold especially here in Ontario. My 07 6.0L Heats up a lot faster now and the coolant temp stays cooler when pulling heavy loads and at the same time helps the engine maintain its own heat even when idling in -20 degree Celsius. Great stuff recommend it for sure. I put this in my Transit and this has helped that van out lots also.
Bottom Line
Yes, I would recommend this to a friend.

Que ce soit pour que le moteur se réchauffe plus vite ou qu'il se refroidissent mieux en période de remorquage, je peux compter sur ce petit plus qui facilite le contrôle de température du moteur!
Bottom Line
Yes, I would recommend this to a friend.

Really seems to help the cooling systems manage Oklahoma summer heat more efficiently. I add a bottle with every coolant change, and an occasional top off between services.
Bottom Line
Yes, I would recommend this to a friend.

For new four cylinder engines in cold especially this is a welcome addition, heat coming on quickly and modestly improving the system's overall performance. Notably impressed with how it has impacted the system health as well!
This heats my car and dirtbike up to operating temperature nice and quick. I use it with amsoil non toxic.
Bottom Line
Yes, I would recommend this to a friend.
