Shell Rotella Extended Life ELC Anti-Freeze + Coolant, Concentrate (1 Gallon, Case of 6)

I love this stuff! I use it in my classic pickup truck and mix with distilled water for my 70/30 mix. I hate the way the newer stuff for trucks has all the junk chemicals in it. This stuff is still pure. I run my truck with a stock 180-degree thermostat and recommended 70/30 mix. I have an electric 1850 cfm fan. With this mix my engine stays between 186 and190-degree Faren height. When it looses the brightness of the colour I flush it and replace every 18 months.

I highly recommend this item

Great product for great price!

This is a quality product and works well.

Great diesel coolant. I have older trucks but decided to run a more modern coolant. The price for the case was good and I have two so I needed a lot.

I would order again

Perfecto

I got the antifreeze and it is what I wanted, but 18 days for delivery is much slower than Walmart.com and even Aliexpress delivering from China. I don't know what is up with Amazon's pathetic delivery lately. It took another week after they told me it was expedited and would arrive in 48 hours, called back, told expedited and only another 48 hours (actually took 72 more). It is impossible to install the thermostat delivered almost immediately without the coolant.
