The Oil Recipe for Less Deposits in Your Engine's Diet

The more you drive, the more your engine performance is challenged. So over time, the motor oil you choose ends up playing an increasingly vital role. Before you can understand the benefits of Castrol GTX, deposit-fighting motor oil, we thought you'd find it intriguing to know how it's made.

Castrol GTX motor oil consists of two main ingredients. There's base oil (85-90%) and performance additives (10-15%). Pay attention now because you never know when a buddy with a dirty, clogged-up engine might ask. The base oil is derived from crude oil.
Cool Oil Fact #1: Crude oil developed naturally from the remains of plants and animals millions of years ago.
Underground is where you'll find crude oil. But don't dig up your backyard yet. It's deep down and pipelines and tankers must transfer it to refineries where they boil it to separate it into components. Then, it's further refined, purified and processed into base oil.
Cool Oil Fact #2: Superior additive technology helps GTX grades provide better protection against oil burn-off than leading oils.
Because of constant bombardment from contaminants like reactive gases, moisture, acids, residual fuel, soot, and even airborne dirt, keeping today's engines clean is a challenge. To help ensure maximum deposit protection and lubrication, our base oils need help. That's why proprietary additives are added to battle engine wear and provide a line of defense against the formation of damaging deposits. When these additives are mixed with our base oil, you get Castrol GTX, a premium, quality motor oil strong enough to keep deposits out of town (and out of your engine!).
How does Castrol GTX motor oil outperform other oils of equivalent grades? You're about to find out...

GTX's Anti-Deposits Technology: Can Your Engine Tell the Difference?

Driving by nature is stressful on an engine. You hit the brakes, speed up and idle for long periods of time. Not only is it stressing your engine, it's also generating huge amounts of heat that can shear and volatize your motor oil. That puts your engine at risk for viscosity and thermal breakdown resulting in decreasing oil flow, increasing oil consumption and more vulnerability to deposits attack. So now what?

GTX to the Rescue!

When it comes to motor oil the key is consistent performance. Otherwise deposits win. The answer is using premium quality oil like GTX, which contains:
  • Maximum deposit protection to help prevent loss of engine power
  • Shear stable viscosity improvers for viscosity breakdown protection
  • Anti-oxidants and detergents for thermal breakdown protection
Engines have feelings, too. Is yours feeling sluggish? Does it have deposits syndrome? Could it be suffering from a breakdown – possibly viscosity or thermal related? Then give it the highest standard of protection in a leading oil to handle the power, speeds, temperatures and demands of today's driving. Give it GTX.

GTX premium motor oil gets high grades compared to other oils.
