HKS 52001-AK148 Super Oil Premium 0W-20 4L API SP ILSAC GF-6A Synthetic LSPI

Vehicle Fitment

• Universal - suitable for all gasoline engines specifying SAE 0W-20 engine oil

Fitment Notes

• Compatible with any vehicle whose manufacturer specifies a W-20 grade engine oil - consult your owner's manual or service specification before switching oil grade; do not substitute 0W-20 in applications requiring a different viscosity grade such as 5W-30 or 5W-40
• Meets API SP and ILSAC GF-6A standards - backwards compatible with all previous API and ILSAC gasoline engine oil categories (SN Plus, SN, SM, etc.)
• Particularly well-suited to modern fuel-economy-optimized engines, hybrid vehicle gasoline engines, and Japanese domestic market vehicles that specify 0W-20 from the factory - including many Toyota, Honda, Subaru, and Nissan applications from 2010s production onward
• Suitable for turbocharged, naturally aspirated, direct injection, and port injection gasoline engines meeting API SP requirements
• Not intended for diesel engines
• Volume is 4 liters - sufficient for most 4-cylinder engine oil changes with filter replacement; verify your vehicle's oil capacity before ordering

Features

• 100% synthetic base oil formulation - full synthetic construction delivers superior film strength, lower volatility, and greater thermal stability than mineral or semi-synthetic alternatives; particularly important in 0W-20 applications where the inherently lower viscosity demands a high-quality base oil to maintain film integrity at operating temperature
• 0W cold-start viscosity provides exceptionally rapid oil circulation at engine startup, including in very cold ambient conditions - the 0W cold rating ensures the oil flows immediately at cold start, minimizing the critical no-lubrication window between startup and full oil pressure that causes the majority of engine wear over time
• 20-weight hot viscosity is the lowest grade commonly specified by Japanese manufacturers for fuel economy optimization - the reduced hot viscosity lowers internal engine friction and pumping losses, contributing to fuel economy improvements versus heavier grades; the full synthetic base maintains this viscosity more consistently through the oil's service life than conventional or semi-synthetic 0W-20 formulations
• API SP certification (2020 standard) - meets the most current gasoline engine oil specification at formulation time, including requirements for improved deposit protection, better oxidation resistance, compatibility with emissions system components, and LSPI resistance in turbocharged GDI engines
• ILSAC GF-6A certification - the parallel fuel economy oil standard confirming the oil meets fuel economy improvement criteria, timing chain wear protection, and Low Speed Pre-Ignition resistance
• LSPI (Low Speed Pre-Ignition) protection - specifically formulated to resist the abnormal combustion phenomenon in modern turbocharged direct injection engines that can cause catastrophic component failure; API SP and GF-6A require LSPI resistance testing that older-standard oils did not undergo
• Allowable maximum temperature of 120°C - appropriate for the operating conditions of modern naturally aspirated and lightly turbocharged engines specifying 0W-20; vehicles running higher sustained temperatures or more aggressive track use should evaluate the 5W-30 Premium (52001-AK145, rated to 130°C) or the Super Turbo Racing oil series instead
• High film retention at elevated RPM and temperature - HKS positions the Super Oil series as a tuning component in addition to a maintenance fluid, reflecting the formulation's capacity to sustain consistent protection under conditions beyond typical daily driving

Product Description

The HKS 52001-AK148 is the Super Oil Premium 0W-20 in the 4-liter size - the lower-viscosity sibling to the 5W-30 Premium (52001-AK145) within HKS's flagship engine oil range. It targets the growing number of modern gasoline engines - particularly from Japanese manufacturers - that specify 0W-20 from the factory as the primary viscosity grade, including a wide range of Toyota, Honda, Subaru, and Nissan applications. The 0W cold-start rating provides rapid oil circulation from the first moment of cranking, minimizing the critical unlubricated window at startup that accounts for a disproportionate share of engine wear over a vehicle's service life.

As a 100% synthetic formulation meeting both API SP and ILSAC GF-6A, it covers all current gasoline engine oil requirements including LSPI resistance for turbocharged direct injection engines, timing chain wear protection, and improved deposit and oxidation resistance over the previous SN Plus standard. The 20-weight hot viscosity reduces internal friction losses to support the fuel economy targets built into modern engine designs, and the full synthetic base maintains that viscosity characteristic through the oil's full service life more consistently than conventional formulations. The maximum allowable temperature is rated at 120°C - appropriate for the operating profile of naturally aspirated and light-load turbocharged engines that specify 0W-20; for higher-temperature applications, the 5W-30 Premium rated to 130°C is the appropriate grade.
