Elantra Oil Grade Specifications

by Jamie Rankin

The Hyundai Elantra is a subcompact sedan that has received high marks over the years for its well-designed interior, its numerous performance and safety features and its economical engine. In order to continue running at the highest level of performance and remain fuel-efficient, the Elantra needs the proper maintenance, including the correct oil.

All Weather

The 2010 Hyundai Elantra owner's manual recommends the use of 5W-20 motor oil for optimum fuel economy in a broad range of temperature conditions, from about -15 degrees Fahrenheit all the way to 120 degrees Fahrenheit. However, this grade of oil is not available in some countries, and 5W-30 is recommended in its place.

Extreme Temperatures

Cars being driven in extremely cold temperatures may require oils with low "winter weight" viscosities. Conversely, cars that are being driven during extremely hot summers or in climates that are warm year-round, such as parts of the southern and southwestern U.S., may require motor oils with higher viscosities. In the case of the Hyundai Elantra, 10W-30 oil is recommended for the best performance in warm weather conditions.

Conventional vs. Synthetic

Conventional motor oil is made from the refining of crude oil. Synthetic oil, while made from natural ingredients, is scientifically engineered so that the molecules are larger and are combined in different ways. While some car owners prefer synthetic oil for its slightly better ability to withstand extreme temperatures, Hyundai recommends using conventional oil in the Elantra.
