The best engine oils are premium full synthetics that offer exceptional thermal stability, wear protection, and sludge prevention. Top picks include Mobil 1 Advanced Full Synthetic, Pennzoil Ultra Platinum, Amsoil Signature Series, Castrol Edge Advanced, and Valvoline Advanced. Always check your car manual for the required viscosity (e.g., 0W-20 or 5W-30) before purchasing.
Park your car on level ground to ensure you get an accurate reading. Turn off the engine and wait 10 to 15 minutes for it to cool down. Note: Manufacturers used to recommend that you check your oil when the engine was cold, to give the oil a chance to settle in the oil pan.

Yes, ExxonMobil manufactures [Toyota Genuine Motor Oil] (TGMO). While Mobil produces the oil, it is generally formulated to Toyota’s specific, proprietary recipes—particularly for high-performance, low-viscosity oils (e.g., 0W-16, 0W-20)—rather than simply being rebranded off-the-shelf Mobil 1.
Most Lexus dealerships use full synthetic Toyota Genuine Motor Oil (TGMO) SAE 0W-20 for modern vehicles. Dealerships use this OEM fluid because it is formulated with special additives to optimize fuel economy and engine performance.
The number one oil brand depends on your specific need. Mobil 1 is the world's leading synthetic motor oil, Moroccanoil is the #1 salon haircare oil in the US, and brands like California Olive Ranch or Graza are top-ranked for cooking.
Both Valvoline and Castrol are top-tier motor oils, and neither is inherently "better" than the other for all scenarios, though they have different strengths. Valvoline is frequently praised for its high-mileage formulations and engine cleaning ability, while Castrol is often considered excellent for high-performance and long-drain intervals.
Pennzoil is owned by the exact same parent company, Shell plc, as it was acquired by the conglomerate in 2002. While they share the same corporate owner, they operate as distinct brands with different base oil chemistries, additive packages, and product lineups.
Most modern vehicles require an oil change every 5,000 to 7,500 miles (or every 6 months) for conventional oil, and 7,500 to 10,000 miles (or once a year) for full synthetic oil. However, the exact interval depends heavily on your vehicle, driving habits, and the type of oil used.

You should generally avoid the 2018 to 2021 model years of the Hyundai Kona. These early models are known for significant mechanical issues, including 2.0L engine piston ring failures and dual-clutch transmission problems.
Based on widespread recalls and reliability reports, the primary Hyundai engines to avoid are the 2.0L and 2.4L Theta II Gasoline Direct Injection (GDI) engines found in 2009–2019 models, as well as the 3.3L V6 Lambda II and some 1.6L turbo engines. These engines are known for high oil consumption, connecting rod bearing failures, and severe knocking, which can lead to engine stalling or engine fires.
Choosing between Toyota and Hyundai depends on what you value most. Toyota is the winner if you prioritize long-term reliability and resale value, while Hyundai is better if you want a lower upfront price, a longer warranty, and more modern technology.
