HKS 52001-AK145 Super Oil Premium 5W-30 4L API SP ILSAC GF-6A Synthetic LSPI

Vehicle Fitment

• Universal - suitable for all gasoline engines specifying SAE 5W-30 engine oil

Fitment Notes

• Compatible with any vehicle whose manufacturer specifies a W-30 grade engine oil - consult your owner's manual or service specification before switching oil grade; do not use in applications requiring a different viscosity grade
• Meets API SP and ILSAC GF-6A standards - backwards compatible with all previous API and ILSAC categories (SN Plus, SN, SM, etc.) and suitable for use in any gasoline engine that calls for those or lower ratings
• Suitable for turbocharged, naturally aspirated, direct injection, and port injection gasoline engines - the API SP standard includes testing for turbocharged engine protection and LSPI resistance applicable to modern downsized, turbocharged direct injection powerplants
• Not intended for diesel engines - the API SP / ILSAC GF-6A certifications are gasoline engine standards
• Volume is 4 liters - sufficient for most 4-cylinder engine oil changes with filter replacement; verify your vehicle's oil capacity before ordering to confirm one bottle is enough

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; the base oil quality directly determines how well the oil maintains its viscosity and protective film under sustained high-temperature, high-RPM operation
• API SP certification (2020 standard) - the most current gasoline engine oil category at time of formulation, API SP adds requirements over the previous SN Plus standard including improved deposit protection, better oxidation resistance, and enhanced compatibility with emissions system components such as catalytic converters and particulate filters
• ILSAC GF-6A certification - the parallel International Lubricant Standardization and Approval Committee standard for gasoline fuel economy oils, confirming the oil meets fuel economy improvement criteria, timing chain wear protection requirements, and low-speed pre-ignition resistance in turbocharged GDI engines
• LSPI (Low Speed Pre-Ignition) protection - specifically formulated to resist the abnormal combustion phenomenon that occurs in modern turbocharged direct injection engines at low speed/high load conditions; LSPI events can cause significant engine damage including broken piston rings and damaged bearings, and the API SP/GF-6A formulation requirement reduces the likelihood of these events compared to older-standard oils
• Allowable maximum temperature of 130°C - the 5W-30 Premium is rated for higher thermal tolerance than the 0W-20 Premium, making it appropriate for applications with higher sustained operating temperatures including high-performance and track-adjacent street use
• High film retention at elevated RPM and temperature - HKS characterizes the Super Oil series as a "tuning part" rather than purely a maintenance item, reflecting the formulation's ability to maintain a consistent protective film under the high-speed, high-load conditions that standard engine oils degrade more quickly under
• Broad versatility across operating conditions - the 5W cold-start viscosity provides rapid oil circulation at startup in cold ambient temperatures, while the 30-weight hot viscosity maintains film thickness under operating temperature; the full synthetic base maintains this multi-grade characteristic more consistently over the oil's service life than mineral or semi-synthetic alternatives

Product Description

The HKS 52001-AK145 is the Super Oil Premium 5W-30 in the 4-liter size - HKS's best-selling engine oil formulation, described by HKS as not merely a maintenance oil but a tuning component designed to sustain stable performance under the high-RPM and high-temperature conditions that performance driving demands. It is a 100% synthetic formulation meeting both the API SP (2020) and ILSAC GF-6A standards, the current top tier of gasoline engine oil certification that includes requirements for LSPI protection in turbocharged direct injection engines, improved deposit control, enhanced oxidation resistance, and timing chain wear protection.

The 5W-30 grade is the more thermally robust of HKS's two Premium grades, rated to a maximum allowable temperature of 130°C versus 120°C for the 0W-20, making it appropriate for vehicles operating in higher ambient temperatures or under more demanding duty cycles. It is a drop-in replacement for any application specifying a W-30 engine oil and is backwards compatible with all prior API and ILSAC gasoline engine oil categories. The 4-liter bottle covers most 4-cylinder engine changes; verify your vehicle's capacity and include filter volume before determining whether one bottle is sufficient.
