Figures are from Toyota's 2025 owner's manuals. Before an oil change or tire swap, owners ask the same questions: which oil, how much, what pressure, what torque. Toyota's own tables answer them, but the two oil grades and the two tire sizes make it easy to buy the wrong thing. This guide collects the numbers from the 2025 Grand Highlander and Grand Highlander Hybrid owner's manuals in one place. **Where these numbers come from.** Section 8-1, "Specifications," in the 2025 Grand Highlander (OM0E111U) and Grand Highlander Hybrid (OM0E112U) owner's manuals. Capacities are reference quantities: after a change, set the level with the dipstick. We did not read the 2024 or 2026 manuals. ## Engine Oil | VERSION | ENGINE | OIL | CAPACITY WITH FILTER | WITHOUT FILTER | | --- | --- | --- | --- | --- | | Gas | 2.4L turbo (T24A-FTS) | SAE 0W-20, ILSAC GF-6A | 5.6 qt (5.3 L) | 5.3 qt (5.0 L) | | Hybrid MAX | 2.4L turbo (T24A-FTS) | SAE 0W-20, ILSAC GF-6A | 5.6 qt (5.3 L) | 5.3 qt (5.0 L) | | Hybrid | 2.5L (A25A-FXS) | SAE 0W-8, JASO GLV-1 | 4.5 qt (4.3 L) | 4.2 qt (4.0 L) | If 0W-20 is not available, the manual allows SAE 5W-20 on the turbo engines, but says to switch back to 0W-20 at the next oil change. For the 2.5L Hybrid, SAE 0W-16 is allowed when 0W-8 is not available, with the same instruction to return to 0W-8. Check the level after the engine has been off about 5 minutes. ## Fuel, Coolant and Spark Plugs | ITEM | GAS 2.4L TURBO | 2.5L HYBRID | | --- | --- | --- | | Fuel tank | 17.8 gal (67.5 L) | 17.2 gal (65 L), per the hybrid manual | | Fuel | Unleaded, 87 AKI or higher | Unleaded, 87 AKI or higher | | Engine coolant | 12.2 qt (11.5 L) | 10.8 qt (10.2 L) | | Intercooler / power control unit coolant | Intercooler 3.3 qt (3.1 L) | Power control unit 2.1 qt (2.0 L) | | Coolant type | Toyota Super Long Life Coolant or equivalent | Same type | | Spark plug | NGK DILZKAR8E7H iridium, gap 0.03 in. (0.7 mm) | See your manual | Toyota says to use only iridium-tipped spark plugs and not to adjust the gap on the gas engine. The manual lists the same fuel tank figure for both hybrid engines. ## Tires and Wheels | ITEM | 18-INCH (TYPE A) | 20-INCH (TYPE B) | | --- | --- | --- | | Tire size | 255/65R18 111H | 255/55R20 107V | | Wheel size | 18 x 7.5J | 20 x 8J | | Cold pressure, front and rear | 35 psi (240 kPa) | 35 psi (240 kPa) | | Spare | T165/90D18 107M at 60 psi | T165/90D18 107M at 60 psi | | Wheel nut torque | 103 ft-lbf (140 N-m) | 103 ft-lbf (140 N-m) | The manual says to add 1 psi front and rear above 100 mph where such speeds are legal, and never to exceed the maximum cold pressure on the tire sidewall. It also says to check the nut torque again soon after a wheel is installed, and to use only nuts designed for that wheel. ## Dimensions and Capacity | ITEM | VALUE | | --- | --- | | Length | 201.4 in. | | Width | 78.3 in. | | Height (unladen) | 70.1 in. | | Wheelbase | 116.1 in. | | Occupants plus luggage | 1,245 lb (7-passenger), 1,410 lb (8-passenger) | | Seating | 7 (2 front, 5 rear) or 8 (2 front, 6 rear) | ## Gear *Links below are affiliate links: toyotadata earns a commission from VEVOR and, as an Amazon Associate, from qualifying Amazon purchases, at no extra cost to you.* | ITEM | USED FOR | BUY | | --- | --- | --- | | Toyota Genuine 0W-20 motor oil, 5 qt jug | Gas and Hybrid MAX engines (T24A-FTS), which take 0W-20 per the manual | [Shop on Amazon](https://www.amazon.com/s?k=Toyota+genuine+0W-20+motor+oil+5+quart&tag=1434042-20) | | Toyota Genuine 0W-8 motor oil | 2.5L Hybrid engine (A25A-FXS), which takes 0W-8 per the manual | [Shop on Amazon](https://www.amazon.com/s?k=Toyota+genuine+0W-8+motor+oil&tag=1434042-20) | | NGK DILZKAR8E7H iridium spark plugs | The gas 2.4L turbo plug listed in the manual.
