what cars use 0w8 oil

[DelAndrew]

0W-8 motor oil is a specific, low-viscosity grade primarily used in newer Toyota and Lexus hybrid models to maximize fuel economy. This ultra-thin oil is designed to reduce internal engine friction, which is critical for the stop-start nature of hybrid powertrains. Using the correct oil, as specified in your owner's manual, is essential for maintaining engine health, warranty coverage, and achieving the advertised fuel efficiency.

The move to 0W-8 is part of a broader industry trend toward lower viscosity oils. The "0W" refers to the oil's flow (viscosity) at winter (W) temperatures, meaning it pumps quickly to protect engine parts during cold starts. The "8" indicates its viscosity at the engine's normal operating temperature (212°F or 100°C), which is thinner than the more common 0W-20 or 5W-30 oils.

The following table lists some of the primary vehicle models that require or recommend 0W-8 oil. Always confirm with your specific vehicle's manual, as requirements can change between model years.

Vehicle Model	Model Year (Approx.)	Engine Type	Key Reason for 0W-8
Toyota Camry Hybrid	2021+	2.5L 4-cylinder Hybrid	Maximizes fuel economy in a high-volume sedan.
Toyota RAV4 Hybrid	2021+	2.5L 4-cylinder Hybrid	Optimizes efficiency for a best-selling SUV.
Toyota Highlander Hybrid	2021+	2.5L 4-cylinder Hybrid	Reduces friction in a larger, family-focused SUV.
Toyota Sienna	2021+	2.5L 4-cylinder Hybrid	Essential for the hybrid-only minivan's high MPG.
Lexus ES 300h	2021+	2.5L 4-cylinder Hybrid	Combines luxury performance with hybrid efficiency.
Lexus UX 250h	2021+	2.0L 4-cylinder Hybrid	Used in compact luxury crossovers for low emissions.
Toyota Venza	2021+	2.5L 4-cylinder Hybrid	Ensures optimal performance in this hybrid-centric SUV.
Toyota Avalon Hybrid	2021+	2.5L 4-cylinder Hybrid	Maintains efficiency in Toyota's former flagship sedan.

It's crucial to understand that 0W-8 is not a universal upgrade. Using it in an engine designed for a thicker oil can lead to inadequate lubrication and potential damage. If you own one of these newer hybrids, stick with 0W-8 for oil changes, preferably at a dealership or a shop familiar with these specific requirements.

I drive a 2022 Toyota RAV4 Hybrid, and the manual is very clear: it needs 0W-8 oil. The dealer told me it’s all about squeezing every last mile out of a gallon of gas. It’s a bit harder to find at your local auto parts store compared to regular oil, so I usually just have the dealership handle the oil change. It’s a small price for keeping the warranty valid and knowing the job is done right for this specific engine.

As a mechanic, I'm seeing 0W-8 pop up more often. It's almost exclusively for the latest generation of Toyota and Lexus hybrids. The engineering is precise—these engines are built with incredibly tight tolerances, and that thin oil is necessary to properly lubricate without creating excess drag. The biggest mistake I see is people assuming 0W-20 is "close enough." It's not. Using the wrong oil can hurt fuel economy and, over time, cause wear.
