Let’s check all the above-mentioned differences between the stp vs ac delco oil filter below.
We found that the STP oil filters have improved cellulose media that delivers the best engine safety and longer life. In addition, the STP Extended Life oil filters contain a synthetic fiber blend media that provides optimal safety for your car’s engine.On the other hand, the AC Delco oil filter comes with thermoplastic end discs that are built of 100 percent recycled material. The AC Delco Gold (Specialty) Ultraguard oil filter is made to endure 5 times bigger force than the maximum engine operating pressures after the oil gets to functioning temperatures for longer life.
You will find a special type of paper filter element in the STP oil filters. This paper filter element holds all the dirt that can destroy your motor. It doesn’t matter in what country the paper filter element was built as the purpose of operation and design of the paper filter element are the same. According to the Grease 1218 study, STP oil filters have larger pore sizes, the same as the media inside of the SuperTech oil filters.
On the other hand, the AC Delco oil filters have much smaller pore sizes. The AC Delco oil filters use a big pleated paper filter element, which is a standard 20 micron and single pass. This paper filter element is firm and endures a lot of pressure with no distortion.
We have found that the STP oil filters generally have 90 percent efficiency for filtering the oil. They deliver the best filth trapping efficiency and filth carrying capacity.
Also, the STP Extended Life Oil Filters like the STP Oil Filter S11473XL come with 99 percent Multi-Pass efficiency, and the removal of particles are only 20 microns.
However, a user from Bob Is The Oil guy doubts that the metal on metal sealing may not be that efficient with STP compared to AC Delco.
In the case of the AC Delco oil filters, they have outstanding filtering abilities with 98 percent multi-pass filtering efficiency at just 25 to 30 microns.
So, the STP Extended Life oil filters are the winner in this category.
Maximum STP oil filters use the clicker style bypass, which does not seem like it could seal very well. They also use combo bypass. On the other hand, AC Delco oil filters use a traditional type of bypass with a rubber-sealed valve. They also use a separate dome bypass.
The STP Extended Life oil filters contain Silicone O-Rings that are not affected by harsh temperatures as low as -40° F and as high as 400° F. In addition, they meet or surpass OEM fit and quality necessities.
The AC Delco oil filters have a cellulose media that entangles particles 1/3 the breadth of human hair to ensure a pure flow of oil to all engine parts.
Oh, the AC Delco Gold (Professional) oil filter has Synthetic end caps. And these are ultrasonically welded to aid in preventing media blocked by adhesives, which you may find in old-style oil filters.
Performance & Longevity
The STP oil filters come with the premium NBR gasket and anti-drain back valve for ensuring the best performance. They are built to deliver up to 5,000 miles of engine safety while used with synthetic oil. Besides, the STP Extended Life oil filters can deliver up to 10,000 miles of engine safety while used with synthetic oil.
As a result, we can say that it is one of the best oil filters for synthetic oil in the market. Also, the STP MaxLife oil filters are rated to last for 15,000 miles. The AC Delco oil filters have a thermosetting adhesive seal that holds the filtering media in its place for compatible, reliable filtration.
In addition, the AC Delco Gold (Professional) oil filter and the AC Delco Gold (Professional) E oil filter have a nylon core for high strength and excellent flow attributes. These oil filters last in the range of 3,000 to 7,000 miles, relying on what oil and oil additives you use. According to some people, they can last for 7500 miles as well.
When we compared the prices between these two leading engine oil filters, we found that the AC Delco oil filter is slightly pricey with some models compared to the STP oil filter. Besides, the general oil filters from both come at around the same price.
