How much oil does a 1989 5.9 Cummins take?
A 1989 5.9 Cummins diesel engine typically requires 12 to 15 quarts of oil for a full oil change. The exact oil capacity can vary slightly depending on the specific engine model and configuration, but this is the general range for this engine.
Detailed Answer
The 5.9-liter Cummins B-series engine was a popular diesel powerplant used in various Dodge Ram trucks and other vehicles in the late 1980s and early 1990s. This robust engine had an oil capacity that could vary depending on factors like the engine model, transmission type, and whether the vehicle had a full-size or extended cab.
According to the information gathered from various automotive resources, the typical oil capacity for a 1989 5.9 Cummins engine is as follows:
- Standard cab, manual transmission: 12 to 13 quarts
- Extended cab, manual transmission: 13 to 14 quarts
- Standard cab, automatic transmission: 14 to 15 quarts
- Extended cab, automatic transmission: 14 to 15 quarts
It's important to always refer to the owner's manual or service information for the specific vehicle to ensure the correct oil capacity is used during an oil change. Using the wrong amount of oil can lead to engine damage or performance issues.
When changing the oil on a 1989 5.9 Cummins engine, it's recommended to use a high-quality, diesel-specific motor oil with the appropriate viscosity grade, such as 15W-40. Proper oil maintenance is crucial for the longevity and performance of these robust Cummins diesel engines.
What oil is best for older diesel engines?
15W-40 (API CJ-4): This oil is suitable for older diesel engines that require API CJ-4 or lower specifications. It provides good protection against wear, deposits, and sludge. 0W-40 (ACEA C3): This oil suits high-performance diesel engines requiring ACEA C3 specifications.

Why did Cummins switch to 10W30?
The most common reason for the change is the increase in fuel economy by switching to lower viscosity oil. Fuel economy improvements are correlated with viscosity.
What happens if I use 5w30 instead of 15w40?
Since 5W-30 and 15W-40 are two different grades, with differing thickness, they cannot be used interchangeably. Most of the time, 15W-40 is suitable for diesel engines, and it has a lot of anti-wear additives. On the other hand, 5W-30 is often recommended for petrol engines and has a different additive profile.
What years to avoid Cummins?
That's three decades of hard work - there are bound to be Dodge Cummins years to avoid after all that time. We recommend staying away from the 1991, 1992, 1993, 1999, 2001, 2003, 2006, 2007, 2008, and 2011 models. Many issues stem from these years.
What happens if I put 10W30 instead of 15w40?
In heavy-duty applications or engines subjected to prolonged high-temperature operation, 10W30 oil may not offer the same level of protection as its counterpart. Potential for increased oil consumption: Due to its lighter viscosity, 10W30 oil may be more prone to vaporization and oil consumption compared to 15W-40 oil.
