Oil Maintenance and Service Tips

Regular oil changes maintain optimal engine performance and protect internal components from wear. Check engine oil level every 1,000 miles or before long trips using the dipstick when the engine is cold and parked on level ground. Modern Lexus IS models using 0W-20 synthetic oil can extend service intervals to 10,000 miles or 12 months, while older models with 5W-30 require changes every 5,000 miles.​

Always replace the oil filter during every oil change to prevent contaminants from circulating through the engine. Use a torque wrench to tighten the drain plug to 27 lb-ft to prevent overtightening or stripping threads. Toyota recommends using Toyota Genuine Motor Oil or equivalent oils meeting API SN, ILSAC GF-6, or higher specifications.​

Service Interval Guidelines

Severe driving conditions include frequent short trips under 5 miles, extensive idling, dusty environments, trailer towing, or extreme temperature operation. Vehicles operating under these conditions require more frequent maintenance intervals regardless of oil type.​

Frequently Asked Questions

What kind of oil does a Lexus IS use?

Modern Lexus IS models (2014-2025) require SAE 0W-20 full synthetic oil. Older models (2006-2013) use SAE 5W-30 full synthetic oil, while first-generation models (1999-2005) can use 5W-30 synthetic blend or full synthetic. Always verify specifications in the owner’s manual for your specific model year.​

How much oil does a Lexus IS take?

Oil capacity varies by engine configuration. The 2.0L turbocharged four-cylinder requires 4.9 quarts, the 2.5L and 3.5L V6 engines take 6.4 to 6.8 quarts, and the 5.0L V8 in the IS F and IS 500 requires 9.6 quarts with filter. Hybrid IS 300h models use 4.5 quarts.​

What is the recommended oil type for a Lexus IS?

Lexus recommends full synthetic oil for all IS models. Use Toyota Genuine Motor Oil or equivalent brands meeting API SN/SN-Plus or ILSAC GF-6 specifications. Popular alternatives include Mobil 1, Castrol Edge, and Pennzoil Platinum full synthetic oils that match the required viscosity grade.​

What is the oil change interval for a Lexus IS?

Lexus IS models using 0W-20 synthetic oil have approved intervals of 10,000 miles or 12 months under normal driving conditions. Models requiring 5W-30 oil should be changed every 5,000 to 7,500 miles or 6 months. Severe driving conditions require 5,000-mile intervals regardless of oil type.​

Can I use 5W-30 instead of 0W-20 in my Lexus IS?

Using 5W-30 instead of the specified 0W-20 is not recommended for newer Lexus IS models. The 0W-20 viscosity provides better cold-start protection, improved fuel economy, and proper oil pressure for modern engine designs. Always use the manufacturer-specified viscosity to maintain warranty coverage and optimal engine protection.​

What oil filter should I use for a Lexus IS?

Use Toyota/Lexus OEM oil filters (part numbers 04152-YZZA6 for most models or 04152-31090 for V8 engines) for best fitment and filtration. Quality aftermarket alternatives include Mobil 1 extended performance filters (M1-110A, M1-113A) and K&N high-flow filters (HP-1008, HP-1017). Always verify compatibility with your specific engine before purchasing.​

Conclusion

The Lexus IS requires different oil specifications depending on model year and engine configuration. Modern IS models (2014-2025) use 0W-20 full synthetic oil with capacities ranging from 4.9 to 9.6 quarts, while older generations specify 5W-30 viscosity. Using manufacturer-approved oil meeting API SN or ILSAC GF-6 specifications ensures proper engine protection and maintains warranty coverage.​

Following recommended oil change intervals of 10,000 miles for 0W-20 synthetic or 5,000 miles for older specifications prevents premature engine wear. Always replace the oil filter during service and torque the drain plug to 27 lb-ft for leak-free operation. Proper oil maintenance maximizes engine reliability, performance, and longevity throughout the vehicle’s service life.​
