Understanding the specific 2018 Subaru Crosstrek oil type is essential for maintaining the longevity and performance of your vehicle. This model, a blend of a hatchback and a compact SUV, utilizes a unique powertrain that demands the right lubricant to ensure optimal operation. Using the incorrect viscosity or failing to meet the manufacturer's standards can lead to decreased fuel efficiency, increased engine wear, and potentially costly repairs down the line.
Manufacturer Specifications for 2018 Models
For the 2018 model year, Subaru provided clear guidelines regarding the engine oil to be used in the standard models. Owners should look for oil that meets the specifications set by Subaru Global Platform, specifically designed to protect the horizontally-opposed "Boxer" engine. The recommended oil type is typically a synthetic blend or full synthetic that adheres to the API SP standard and meets the ILSAC GF-6 requirements.
Viscosity Grade Recommendations
The viscosity, or thickness, of the oil is a critical factor that changes with temperature. Subaru specifically recommends 0W-20 motor oil for the vast majority of 2018 Crosstrek trims. This low-viscosity oil is engineered to flow quickly at cold startup, reducing friction and wear on critical engine components during the initial moments of operation. It also contributes to better fuel economy and provides adequate protection during normal high-temperature driving conditions.
Consequences of Using the Wrong Oil
While it might be tempting to use a heavier oil, especially in older vehicles or warmer climates, it is strongly advised against for the 2018 Crosstrek. Using an oil with a viscosity higher than 0W-20, such as 5W-30, can lead to sluggish performance and reduced fuel efficiency. Furthermore, non-compliant oils may not provide the necessary protection for the unique stresses placed on the Boxer engine, potentially voiding the vehicle's warranty.
Synthetic vs. Conventional Options
When selecting the 2018 Subaru Crosstrek oil type, you have the choice between conventional, synthetic blend, and full synthetic. While the engine is designed to run on synthetic oil, using a synthetic blend is often a cost-effective middle ground that still meets the manufacturer's standards. Full synthetic oil offers the best performance in extreme temperatures and provides superior protection and longevity, making it the ideal choice for drivers who subject their vehicles to severe driving conditions.
Oil Capacity and Filter Specifications
To properly maintain your vehicle, you need to know not just the type, but also the quantity of oil required. The 2018 Subaru Crosstrek typically has an oil capacity of approximately 4.4 quarts for a standard oil change. It is crucial to replace the oil filter with a high-quality filter that is compatible with the 2.0-liter FB20 engine to ensure proper filtration and prevent contaminants from circulating through the lubrication system.
Intervals and Maintenance Schedules
Even with the correct 2018 Subaru Crosstrek oil type, the benefits will diminish over time. Subaru recommends adhering to the maintenance schedule outlined in the owner’s manual, which generally suggests an oil change every 6,000 miles or 6 months, whichever comes first. Consistently following this schedule ensures that the oil remains effective at dispersing heat and protecting the engine from sludge buildup.
Special Considerations for CVT Fluid
It is important to note that the 2018 Crosstrek is equipped with a Continuously Variable Transmission (CVT), which requires its own specific fluid. The oil type for the engine and the transmission fluid are entirely separate entities. The CVT requires Subaru Type ATF, and using the wrong fluid can cause damage to the transmission, leading to expensive repairs. Always double-check that you are purchasing the correct fluids for the specific systems of your vehicle.
