Intense heat wrecks engines—unless you’re using AMSOIL’s Dominator Coolant Boost! Certified Lube in Houston, TX, reveals how to keep your ride cool, fast, and summer-proof.
Houston summers don’t play around. When June rolls in, it brings heat that can seriously strain people and engines. Your car’s cooling system is your first line of defense against the scorching Texas sun, and it's more important than ever to ensure your engine is protected and performing at its best. That’s where AMSOIL offers premium synthetic motor oils and performance products designed for precisely these conditions.
Let’s talk about how AMSOIL’s Signature Series motor oil and Dominator Coolant Boost can make a real difference during a Houston summer.
In June, Houston temperatures regularly exceed 90°F, and things get even hotter under the hood. In this heat, engine oil can break down faster, reducing its ability to lubricate and protect. Over time, this leads to increased wear, poor fuel efficiency, and, in worst cases, engine failure.
But it's not just the oil—your entire cooling system is working harder. Radiators, coolant, and thermostats are under more pressure to keep engine temperatures within a safe range. And the risk of overheating skyrockets when you're idling in traffic or hauling gear across town.
This is precisely why upgrading from conventional fluids to something engineered for performance is worth it. AMSOIL products are made to thrive in extremes, especially summer in the South.
Let’s start with AMSOIL’s flagship motor oil: the Signature Series Synthetic Motor Oil. Designed for durability and high performance, this oil offers up to 75% more engine protection against horsepower loss and wear than conventional oils.
For Houston drivers, that translates to:
Signature Series is ideal for drivers who want to “set it and forget it.” With Houston's traffic and high temperatures, many oils degrade fast. AMSOIL’s formulation resists oxidation and deposits, keeping your engine clean and cool no matter how brutal the weather.
Even the best motor oil can’t do the job alone if your cooling system isn’t up to par. That’s where Dominator Coolant Boost becomes a true difference-maker.
This high-performance additive improves the heat-transfer efficiency of your vehicle’s coolant, helping your engine stay cooler, even when temps soar. It’s formulated to reduce engine temperatures up to 25°F in high-performance cars, which can make a real difference when you’re stuck in traffic on a humid Houston afternoon.
Here’s why Dominator Coolant Boost deserves a spot in your garage:
Dominator Coolant Boost isn’t just for racers. If your vehicle is exposed to high-heat conditions—all summer in Houston—this product can protect your engine and improve overall cooling efficiency. And that means less strain on your vehicle and more peace of mind.
If you’re the type who typically waits until your next sticker says it’s time for an oil change, June is the perfect time to get ahead of the game—especially in Houston. Regular oil changes are good but not always enough when dealing with extreme temperatures and humid Gulf Coast conditions.
Using AMSOIL synthetic motor oil instead of conventional oil is one of the easiest upgrades for summer reliability.
