Direct injection and turbochargers are a powerful combination, but using available high torque at low speed can lead to abnormal combustion that not only degrades performance, but also causes damage. This low-speed pre-ignition (LSPI) occurs when the mixture of air and fuel—injected directly into the combustion chamber instead of the intake port—ignites before the spark and as the piston is still moving upward, resulting in excessive cylinder pressure (or “knock” in mild cases).
Driven Racing Oil has conducted research confirming that an oil’s detergent chemistry can impact LSPI. To meet this problem head-on, Driven has developed the first line of motor oil formulated, tested, and proven to protect direct-injection engines better than API oils: the DI series of synthetic performance motor oils.
Available in 0W-20 (DI20 #18206), 5W-30 (DI30 #18306), 0W-40 (DI40 #18406), and 10W-60 (DI60 #18606), DI synthetic performance motor oils are ahead of curve when it comes to the new 2018 API SN+ engine oil spec, providing an immediate solution for direct-injection engines. They combat LSPI and contain additives to prevent soot-related wear and reduce intake valve deposits typically caused by volatile off-the-shelf engine oils.
