Manufactured to IATF 16949 quality standards.
Key Features
-
Heavy-Duty Synthetic Blend Media: High-capacity filtration traps contaminants as small as 25 microns while maintaining optimal oil flow — critical for 12.8L-15.6L engine protection.
-
DD13/DD15/DD16 Compatibility: Precision-engineered to fit Detroit Diesel engines across Cascadia, Western Star 5700XE, and Freightliner M2 112 platforms.
-
Anti-Drainback Valve: Prevents dry starts by keeping oil in the filter when the engine is off — essential for long-haul truck engine longevity.
-
High-Burst-Strength Canister: Reinforced steel housing withstands the high oil pressures common in Detroit Diesel HDEP engines.
-
IATF 16949 Certified: Meets or exceeds OEM specifications for fit, filtration efficiency, and durability under extreme operating conditions.

Maintenance Interval
Detroit Diesel recommends oil and filter changes based on duty cycle. Under normal highway operation: every 25,000-50,000 miles. Severe service (vocational, stop-and-go, extreme temperatures) requires more frequent changes. Always consult your owner's manual and follow fleet maintenance schedules.
Frequently Asked Questions
Q: Will this fit my 2018 Cascadia with DD15?
A: Yes. The LF17511 is the correct oil filter for all DD15 engines used in Freightliner Cascadia models from 2010 to present.
Q: Is this an OEM Detroit Diesel filter?
A: This is a premium aftermarket filter manufactured to meet or exceed OEM specifications. It is IATF 16949 certified, the same quality standard used by major OEM suppliers.
Q: How often should I change this filter?
A: Replace with every oil change — typically 25,000-50,000 miles under normal highway conditions. Severe-duty applications should follow shorter intervals.
Q: Does this filter have an anti-drainback valve?
A: Yes. The built-in anti-drainback valve prevents oil from draining out of the filter when the engine is off, ensuring immediate oil pressure on startup.
Q: Does it fit DD13 and DD16 engines too?
A: Yes. The LF17511 fits DD13 (12.8L), DD15 (14.8L), and DD16 (15.6L) Detroit Diesel engines.
