Pontiac Grand Prix Oil Type & Capacity

Frequently Asked Questions

What type of oil does a Pontiac Grand Prix use?

Most newer Pontiac Grand Prix models (2010+) use 0W-20 full synthetic oil. Older models typically use 5W-30. The exact specification depends on your engine — check the oil cap or owner's manual for the definitive answer.

How many quarts of oil does a Pontiac Grand Prix take?

Oil capacity for the Pontiac Grand Prix ranges from 4.0 to 6.5 quarts depending on engine size and whether you're replacing the filter. Four-cylinder engines are typically on the lower end, V6 and V8 on the higher end.

Can I use conventional oil in my Pontiac Grand Prix?

For 2010+ Pontiac Grand Prix models, full synthetic is strongly recommended (and often required). Older models can typically use conventional, but synthetic provides better protection, longer drain intervals, and improved fuel economy.

How often should I change the oil in my Pontiac Grand Prix?

Modern Pontiac Grand Prix models typically call for oil changes every 5,000 - 10,000 miles depending on driving conditions. Older models should stick to 3,000 - 5,000 miles. Severe driving (towing, extreme heat, short trips) may require more frequent changes.

What happens if I use the wrong oil in my Pontiac Grand Prix?

Using oil that's too thick can reduce fuel economy and increase engine wear during cold starts. Oil that's too thin may not protect adequately under load. For best results, always use the manufacturer-specified weight.
