Lexus 350 Oil & Filter Change Guide

Changing the oil and oil filter on your Lexus ES or RX is a fundamental maintenance task that every DIY enthusiast can master. It's not just a cost-saving measure compared to dealership servicing; it's a crucial step in preserving engine health and ensuring the longevity of your luxury vehicle. This guide will walk you through the process, from gathering the necessary tools to the final checks, making it a straightforward and rewarding experience.

This comprehensive guide is applicable to Lexus ES and RX models manufactured between 2005 and 2014. Performing this service yourself not only saves you money but also provides the satisfaction of hands-on automotive care. Let's get started!

Essential Tools and Materials

Before you begin, ensure you have all the required items. Having everything at hand will streamline the process and prevent unnecessary interruptions.

Here's a checklist:

• Floor Jack
• Jack stands or car ramps
• Oil catcher or drain pan
• 14mm wrench
• Eye protection (safety glasses)
• Gloves (optional, but recommended for cleanliness)
• Paper towels or clean rags
• Wheel chocks or sturdy blocks of wood
• Oil filter wrench (specific size for Lexus may be needed, e.g., 65mm)
• 7 quarts of 0W-20 synthetic oil (check your owner's manual for exact specification)
• New oil filter (part #04152-YZZA1 is common for these models, but always verify)
• 3/8" socket drive wrench
• Funnel

Step 1: Safely Elevate Your Lexus

Safety is paramount when working under a vehicle. You have two primary options for safely lifting your Lexus:

• Using Jack Stands: Position your floor jack under the designated jacking point (refer to your owner's manual). Lift the vehicle as high as safely possible. Carefully place jack stands under the vehicle's frame, ensuring they are positioned securely. Lower the vehicle slowly onto the jack stands. Never work under a car supported only by a jack.
• Using Ramps: Drive your Lexus slowly onto the car ramps until the front wheels are securely on the flat portion. Engage the emergency brake firmly. For added security, place wheel chocks or blocks of wood behind the rear tires to prevent any accidental rolling.

Regardless of the method, ensure the car is stable and level before proceeding. Figure 1 illustrates the importance of using jack stands or ramps for safe working conditions.

Step 2: Address the Oil Filter Housing

The oil filter on these Lexus models is integrated into a housing unit, which requires a slightly different approach than a traditional spin-on filter.

1. Locate the Drain Plug: Underneath the car, find the oil filter housing. You'll notice a small drain plug at the bottom of this housing.
2. Attach Drain Tube: Using your 3/8" socket drive wrench, carefully remove this drain plug. Immediately insert the provided oil filter drain tube (often included with new filters or sold separately) into the opening. This tube will direct the oil into your drain pan.
3. Drain the Filter Housing: Allow the oil from the filter housing to drain completely. This is a crucial step to minimize mess when you remove the housing itself.
4. Remove the Housing: Once the housing is drained, use the appropriate oil filter wrench (a 65mm wrench is commonly required for Lexus housings) to unscrew the entire filter housing. Be prepared for a small amount of residual oil to drip out.
5. Inspect and Replace O-rings: Carefully remove the old oil filter element from the housing. Inspect the housing for any debris or damage. Crucially, locate and remove the old rubber O-rings from the housing and the drain plug. Clean the housing thoroughly. Lubricate the new O-rings with a little bit of fresh oil and install them in their respective grooves. This is vital to prevent leaks.
6. Install New Filter and Plug: Insert the new oil filter element into the housing. Screw the housing back onto the engine block by hand until snug, then tighten it slightly with the filter wrench (refer to your manual for torque specifications if available, but hand-tight plus a quarter turn is often sufficient). Reinstall the drain plug and tighten it securely with the 3/8" socket drive wrench.

Step 3: Drain the Engine Oil

Now it's time to drain the main oil supply from the engine's oil pan.

1. Prepare the Fill Cap: Open the bonnet (hood) of your Lexus. Locate and unscrew the oil fill cap on top of the engine. Loosening this cap helps the oil drain more freely by allowing air to enter the crankcase.
2. Position the Drain Pan: Get back under the vehicle and locate the oil pan. You'll see a large drain plug at the lowest point of the oil pan. Position your used oil drain pan directly beneath this plug.
3. Remove the Drain Plug: Using the 14mm wrench, slowly and carefully loosen the oil drain plug. Once it's loose enough, you can try to unscrew it the rest of the way by hand. Be ready for the hot oil to gush out. As mentioned earlier, wearing eye protection and gloves is highly recommended during this step.
4. Allow Complete Drainage: Let the old engine oil drain completely into the pan. This process can take several minutes. Ensure the drain pan is large enough to hold all the old oil.

Step 4: Refill with Fresh Oil

With the old oil drained, it's time to add the new, clean oil.

1. Replace the Drain Plug: Once the oil has finished dripping, clean the drain plug and the area around the drain hole with a rag. Screw the drain plug back into the oil pan by hand to avoid cross-threading, then tighten it securely with the 14mm wrench. Do not overtighten.
2. Install the New Oil Filter: Ensure the new oil filter is properly seated in its housing, and the housing is tightened.
3. Add New Oil: Place the funnel into the oil fill valve on top of the engine. Carefully pour in the specified amount of 0W-20 synthetic oil. For Lexus ES and RX 350 models, this is typically 7 quarts, but always confirm with your owner's manual.
4. Replace Fill Cap: Once the oil is added, replace and tighten the oil fill cap securely.

Step 5: Final Checks and Cleanup

The final steps are crucial for ensuring a successful oil change and maintaining your vehicle.

1. Initial Leak Check: Before starting the engine, take a moment to visually inspect under the car. Check around the oil filter housing and the oil drain plug for any obvious signs of leaks.
2. Start the Engine: Start the engine and let it run for a few minutes. Allow it to reach its normal operating temperature. The oil pressure warning light on your dashboard should go out shortly after starting.
3. Post-Run Leak Check: With the engine running, carefully check underneath the vehicle again for any leaks around the drain plug and the oil filter housing. If you notice any drips, immediately shut off the engine and tighten the offending component slightly.
4. Lower the Vehicle: Once you're confident there are no leaks, turn off the engine. If you used jack stands, carefully jack the car up slightly, remove the jack stands, and then lower the vehicle. If you used ramps, simply drive the car off the ramps.
5. Clean Up: Use paper towels or rags to clean up any spilled oil on the engine or under the car.
6. Proper Disposal: This is extremely important. Used motor oil and oily rags are hazardous waste. Take your used oil and old filter to an authorized recycling center or an auto parts store that accepts them. Never pour used oil down drains or into the environment.

Oil Change Costs and Maintenance Schedule

While performing the oil change yourself is cost-effective, understanding the general costs associated with Lexus maintenance can be helpful for budgeting.

Average Lexus Maintenance Costs

Lexus vehicles, known for their reliability and luxury, generally have lower average annual maintenance costs compared to many other luxury brands. According to industry data, the average annual maintenance cost for a Lexus is around $551, which is significantly lower than the industry average. This affordability is partly due to Lexus's strong ties with Toyota, sharing many reliable components and engineering principles.

Model-Specific Costs

Maintenance costs can vary slightly between Lexus models:

As you can see, the ES 350 and RX 350 fall within the more affordable range for Lexus maintenance.

Factory-Recommended Maintenance Schedule

Following the manufacturer's recommended service schedule is key to maintaining your Lexus's performance and reliability. Lexus typically offers complimentary scheduled maintenance for the first two visits (usually at 6 months/5,000 miles and 12 months/10,000 miles). After that, regular servicing is generally recommended every 6 months or 5,000 miles.

Always consult your owner's manual for the most accurate and specific maintenance schedule for your particular Lexus model and year.
