What is the best oil for 2015 Acura TLX?
The best oil for a 2015 Acura TLX is a full synthetic 0W-20 engine oil that meets API SN (or newer) and ILSAC GF-5 specifications. Both TLX engines—the 2.4-liter inline-four and the 3.5-liter V6—are designed to run on 0W-20, with Acura/Honda Genuine 0W-20 or equivalent premium synthetic oils providing optimal protection and efficiency.
Engine options and oil needs
In 2015, the TLX offered two powertrains. Despite the difference in displacement, both engines share the same recommended oil viscosity: SAE 0W-20 synthetic. Using a high-quality full synthetic lubricant helps ensure efficient cold starts, robust protection, and longer oil-change intervals under normal driving conditions.
Manual guidance and what to buy
Acura’s 2015 TLX owner’s manual specifies the use of 0W-20 synthetic engine oil that meets API SN (or newer) and ILSAC GF-5 standards. It calls for a full synthetic product and outlines maintenance- minder-driven change intervals, typically around 7,500 miles under normal driving. In severe conditions—short trips, extreme temperatures, or heavy loads—the interval may be shorter. Always confirm with the latest manual or your dealer, especially in extreme climates.
Common 0W-20 full-synthetic oils that meet spec
The following 0W-20 full-synthetic oils are widely used by TLX owners and meet API SN/GF-5 specifications. Look for bottles that clearly state 0W-20 and API SN or newer with ILSAC GF-5 compatibility.
- Honda/Acura Genuine 0W-20 Synthetic Oil
- Mobil 1 0W-20 Advanced Full Synthetic
- Pennzoil Platinum Full Synthetic 0W-20
- Castrol EDGE 0W-20 Full Synthetic
- Valvoline Advanced Full Synthetic 0W-20
- Royal Purple 0W-20 Full Synthetic
Any of these oils will meet the required specification as long as they are labeled 0W-20 and carry API SN or newer plus GF-5 compatibility. If in doubt, choose Honda/Acura Genuine oil or consult your dealer for a recommended SKU.
Oil-change intervals and maintenance tips
With 0W-20 synthetic oil, the TLX typically uses a maintenance minder-driven interval, commonly around 7,500 miles under normal driving. In severe driving scenarios, such as frequent short trips or extreme temperatures, the interval may be shorter (often around 5,000 miles). Always follow the Oil Life System on the dashboard and the interval suggested in the owner’s manual.
Choosing the right option for your climate and lifestyle
In practice, sticking with the factory-recommended 0W-20 synthetic oil yields the best balance of protection, efficiency, and warranty compliance. Cold climates benefit from the improved cold-start protection of 0W-20, while hot climates benefit from stable viscosity. Premium synthetic oils can offer marginal gains in cleanliness and performance, but the most important factor is selecting a proper 0W-20 grade that meets API SN/GF-5 and following the maintenance schedule.
Summary
The best oil for a 2015 Acura TLX is a full synthetic 0W-20 that meets API SN and ILSAC GF-5. Choose trusted brands such as Honda/Acura Genuine 0W-20, Mobil 1, Pennzoil Platinum, Castrol Edge, Valvoline, or Royal Purple, and adhere to the maintenance minder-driven oil-change intervals outlined in the manual. Always verify the latest guidance with your owner’s manual or a certified Acura technician.
