Frequently Asked Questions
What causes the Hemi tick?
The Hemi tick is often attributed to issues within the valvetrain, specifically worn or failing hydraulic roller lifters, camshaft wear, or issues with the multi displacement system (MDS) components. These issues can lead to excessive clearance or improper lubrication, causing a distinct ticking noise from the engine. While oil can help mitigate symptoms, it typically cannot fix a mechanical failure.
Can a different oil viscosity help with Hemi tick?
While some owners experiment with slightly different viscosities, it is critical to always adhere to your vehicle manufacturer’s recommended oil viscosity, typically 5W-20 or 5W-30 for Hemi engines. Using an incorrect viscosity can potentially lead to other engine problems or void your warranty. The quality of the oil, specifically its synthetic base and additive package, is generally more important than a minor viscosity deviation.
Should I use a full synthetic oil for my Hemi?
Yes, based on our research and expert consensus, using a high quality full synthetic oil is highly recommended for Hemi engines, especially those with the MDS system. Full synthetics offer superior wear protection, better resistance to thermal breakdown, and enhanced cleanliness compared to conventional or synthetic blend oils. These properties are crucial for the longevity and performance of complex valvetrain components.
How often should I change my oil to address Hemi tick?
Even with a premium full synthetic oil, it is advisable to follow your vehicle manufacturer’s recommended oil change intervals, typically outlined in your owner’s manual. Some advanced synthetic oils offer extended drain intervals, but for an engine exhibiting Hemi tick, more frequent oil changes within the manufacturer’s guidelines, coupled with a high quality synthetic, may help maintain optimal lubrication and cleanliness.
Will any oil completely eliminate the Hemi tick?
No, an engine oil, regardless of its quality, cannot completely eliminate a Hemi tick caused by a mechanical defect such as a worn lifter or camshaft. While a high quality full synthetic oil can potentially reduce the audible severity of the tick and provide better protection against further wear, it is not a repair. A persistent Hemi tick typically requires a mechanical inspection and repair by a qualified technician.
