Carbon Deposit Q&A
Follow along to learn more about carbon deposits.
Carbon Deposits and Direct Injection Engines
The primary cause of these problems is that fuel and added detergents are not hitting the back of the intake valves.
Oil and Carbon Deposits
Here’s how oil can influence carbon deposits.

Oil And Carbon Deposits
Gains in power and fuel economy have been realized with direct injection and turbocharging.
The Carbon Deposit Conundrum
Engine carbon deposits have been around for more than 100 years. They start out as fresh oil and gasoline. The engine uses heat, compression and combustion to turn most of the fuel into power. But, during some combustion events, a droplet of fuel or oil is transformed into a substance that can become a carbon deposit. This typically happens when there are conditions that are outside of the normal operating conditions.
The Oil And Carbon Deposit Connection
Oil is made of carbon atoms. The oil in the crankcase is a highly refined carbon-based substance that is found in long chains with strong bonds that are typically uniform in size and shape. They work well together to lubricate the engine and protect the bearings, as they are engineered to withstand extreme temperatures.
Curing Carbon Deposits On Direct Injection Engines
Direct injection improves fuel economy by injecting the correct amount of fuel for the conditions in the combustion chamber. But, it is not a perfect science: Carbon deposits can form on the intake valves, piston and other surfaces in the combustion chamber.

Conventional oil that has high volatility will cause more vapors and make carbon deposits worse. Synthetic oil with low volatility can reduce vapors and prevent carbon from forming on the valves. Sponsored by Auto Value and Bumper to Bumper.
