What is the oil capacity for the 6.6 Duramax Diesel engine? All of the engines have the same capacity since the introduction of the engine back in 2001. The manufacturers rating for the 6.6 Duramax oil capacity is 10 quarts, but you will probably only need around 9 quarts. That is because the way the oil pan on the bottom is formed. You can’t get it all out. There will always be a little left in the engine. Make sure that your engine is at operating temperature before doing the oil change and you will get the most oil out of the engine. Be sure that you do not have the truck on an angle as this will hinder you from getting all of the oil out.

Read about the best oil filter for Duramax Diesel engines and gain a better understanding of the best oil filter for synthetic oil that can lead to an improved engine performance and higher mileage. In general, the best oil filters will reduce contaminants from entering your engine and improve their removal from your engine’s oil.
People are often confused about what defines an absolute or nominal micron rating in oil filters, but it’s really very simple. A nominal micron rating means that 99% of particles in this size range will be captured by the filter while an absolute micron rating means that 100% of particles in this range will be captured by the filter. If your vehicle requires an absolute micron oil filter , make sure you buy one with this rating.
Oil filters should be replaced with each oil change, and the best oil filters will protect your engine from environmental contaminants such as dirt, sand and water. If the best oil filter for your vehicle doesn’t have a great micron rating or other superior characteristics, then it won’t do much good at all. As always, read the reviews before buying an oil filter so you can ensure it is best for your truck.
The best way to find out which filter works best for your truck is to check its owner’s manual or ask a certified mechanic . You might also want to consider purchasing an OEM (original equipment manufacturer) part as they are designed specifically for each individual vehicle by the same company that manufactured it.
The Duramax Diesel 6.6L engine oil filter should be changed every 10,000 miles or when the “Change Engine Oil” message is displayed by the oil life monitoring system. Below are some of the best oil filters for synthetic oil in the 6.6 Duramax diesel engine.
Best Oil Filter for Duramax Diesel Engines – Top Rated Filters Listed
AC Delco PF2232 Oil Filter
Equipped with 98 percent multi pass filtering efficiency at 25 to 30 microns for excellent filtering capabilities. Finding a filter that is strong becomes imperative to prevent potential problems. That is why AC Delco oil filters utilize glass-filled nylon for higher strength and greater flow. Nylon is far less likely to tear, rip or shred.

Fleetguard LF16102 Oil Filter
Rated at 99% efficiency for 30 microns.
In the 1980s, Cummins Filtration took another step forward with the introduction of combination full flow/by-pass filtration in the patented LF3000™. The LF3000™ led the way for today’s advanced lube filtration systems, which provide increased engine life over all service intervals, as well as:
Extended service intervals
Increased vehicle uptime
Decreased vehicle maintenance costs
Reduced disposal costs
StrataPore® Media
By implementing the revolutionary StrataPore multi-layered media in the 1990s, the combo filter was improved even more. StrataPore as introduced in the full flow section to work in combination with the stacked discs to remove the smallest dirt particles, which cause the most engine damage. This configuration reduces engine wear by as much as 60% in some applications.
Venturi™ Combo System
The technology was taken even further with the introduction of the Venturi™ Combo. The OEM-approved Venturi allows the lube system to perform up to four times as long and remove up to three times the contaminants as a full synthetic filter. The patented Venturi nozzle provides a low-pressure zone for the oil to flow through the pleated media for increased efficiency. This innovative technology results in longer life and better performance for your vehicle. And, unlike its competitors, the Venturi was tested in a real world environment, not bench tested.
NanoNet® Media Technology
With advanced research and media manufacturing capabilities, Cummins Filtration has developed nanofiber media for Fleetguard lube filters. The pairing of NanoNet® media with StrataPore® media has created a new breed of lube filter that offers higher efficiency, higher capacity and the best cold flow vs restriction available. This makes the LF14000NN the best choice for providing maximum protection for your Cummins ISX engine.
Baldwin 1441 Oil Filter
- Micron rating of 9.8 Nominal (95% efficient) and 27 Absolute (largest particle that will pass through filter)
- Baldwin spin on oil filters protect your engine from wear particles that can otherwise lead to premature parts failure. Longer drain intervals requires filters that have both high capacity and the ability to withstand the rigors of time and temperature without failing or going into bypass. Baldwin’s lube filters are up to the challenge.
- Keep contaminants causing damage, away from the sensitive parts of the engine
- Gaskets provide exterior seal between the filter and engine
- Highly durable and reliable
- Improves engine life
