How does the 15607-2210 oil filter improve fuel efficiency?
The 15607-2210 oil filter does not create power or fuel efficiency — it stops diesel fuel (and engine power) from being wasted. It eliminates friction, parasitic losses, turbo wear and combustion inefficiencies that drain fuel economy, preserving the D-4D diesel engine’s factory-designed ability to convert diesel fuel into usable power with zero unnecessary waste.
