Choosing the right oil filter for your LS engine (5.3, 6.0, 6.2) matters for long-term engine health. Here’s the breakdown.
LS Engine Oil Filter Thread Size:
All LS engines use the same oil filter thread: 22mm x 1.5 pitch. Common filter part numbers include:
- AC Delco PF48 / PF63
- Motorcraft FL-2016 (cross-reference)
- Wix 57060 / 51516
OEM vs. Aftermarket:
ACDelco UltraGuard Gold (Best OEM Value)
The ACDelco UltraGuard Gold is the OEM-equivalent filter from the company that supplies GM dealers. Excellent filtration, correct dimensions, and proven performance. Usually under $10.
Wix 57060 (Best Aftermarket)
Wix makes filters with robust construction, quality filtering media, and anti-drain back valves that maintain oil pressure on startup.
Mobil 1 Extended Performance Filter
The Mobil 1 M1-108 filter pairs naturally with Mobil 1 oil. Built for extended drain intervals with a high-capacity filter media.
Amsoil Ea Oil Filter
Amsoil’s Ea series has the best filtering efficiency available for extended drain intervals.
What to Avoid:
Cheap generic filters (Fram orange box, Puro-labs) have lower-quality media and less robust bypass valve ratings. For a high-mileage LS or one prone to AFM lifter issues, quality filtration matters more.
Change Interval:
Match the filter to your oil change interval. A standard filter is fine for 5,000-7,500 miles. For extended intervals with quality synthetic (Mobil 1 5W-30), use an extended-performance filter.
