What type of engine oil is best for the RAV4?
2 Answers
Toyota's engine manufacturer recommends using engine oil with a viscosity of 0w-20 or 5w-30. For new vehicles, it is advisable to use 0w-20 viscosity oil as it can reduce engine resistance and fuel consumption. 1. Lubrication and friction reduction: Forms an oil film on the surfaces of two sliding components to prevent friction during operation, ensuring smooth movement. 2. Cleaning and dispersion: High-quality oil can flush away surface contaminants on components through oil flow, adsorb tiny metal fragments inside the engine, and then rely on the piston oil ring to scrape them into the oil pan. 3. Cooling: The engine generates high temperatures during operation. When the oil reaches the operating parts, it absorbs heat and carries it away, aiding in component cooling. 4. Sealing and leakage prevention: Forms a sealing ring between the piston ring and piston via an oil film to prevent combustion exhaust gases from entering the crankcase. 5. Rust and corrosion prevention: High-quality oil adheres to component surfaces, preventing contact with air, acidic substances, and harmful gases, protecting the engine from corrosion by atmosphere and water.
Just helped my neighbor with RAV4 maintenance a couple of days ago, so I've thoroughly researched engine oil. The owner's manual for the new RAV4 clearly recommends 0W-20, and Toyota Genuine Oil works perfectly. If your car has over 80,000 kilometers or you often floor the accelerator, 5W-30 would be more reliable. Last winter in Harbin, I tried 0W-16 – cold starts were exceptionally smooth, but older cars shouldn't bother with it. Full synthetic oil can last up to 10,000 km between changes, making it way more cost-effective than mineral oil. Always check for the API SP or GF-6A certification mark – those random brands from gas stations are no good. During maintenance, remember to ask the mechanic to check the dipstick level, something many people overlook.
