What kind of oil does a 99 Acura TL take?
The quick answer: it uses 5W-30 engine oil, with an oil capacity of about 4 quarts (roughly 3.8 liters) including the filter. Conventional, synthetic, and synthetic-blend 5W-30 oils are all acceptable, depending on climate and maintenance preferences.
Below is a fuller explanation of what this means for a 1999 Acura TL, including how to choose the right oil, how much you’ll need, and how often you should change it.
Viscosity and oil type for the 1999 TL
The 1999 TL is powered by a 3.2-liter V6 that calls for 5W-30 motor oil under typical driving conditions. This viscosity provides solid cold-start protection and reliable lubrication across the engine’s operating range. You may use conventional, synthetic, or synthetic-blend 5W-30 oil, as long as it meets current API service standards.
Oil options
To help you decide, here are the common oil choices that fit the 5W-30 requirement for this model year:
- Conventional 5W-30 motor oil
- Synthetic 5W-30 motor oil
- Synthetic-blend 5W-30 motor oil
Whichever option you choose, ensure the oil grade is 5W-30 and that it carries a current API certification appropriate for gasoline engines.
Oil capacity and change intervals
The engine’s capacity is about 4 quarts (roughly 3.8 liters) with the oil filter. After a change, check the level with the dipstick and top up if necessary to reach the proper mark. Typical change intervals are around every 3,000 miles for conventional oil and roughly 5,000–7,500 miles for synthetic oils, depending on driving conditions and manufacturer guidance. Always follow the maintenance schedule in the owner’s manual or your trusted mechanic’s recommendations.
Practical tips for maintaining the right oil
Record the oil type, grade, and change date in a maintenance log, and replace the oil filter with every oil change to ensure proper filtration and protection for the V6 engine.
Summary
For a 1999 Acura TL, use 5W-30 engine oil in any of conventional, synthetic, or synthetic-blend forms, with an approximate capacity of 4 quarts including the filter. Follow the vehicle’s manual for exact intervals and specs to keep the V6 running smoothly.
