Full filter mileage 2017 vs 2015


Recommended Posts

Entirely different system and filter.

 

(And FWIW, GM recommended that the LML filter be changed at 2 yr OR 22,500 miles OR filter minder, whichever came first)

Have 8000 miles on the 2017 and 60% remaining on fuel filter. The 2015 went well over 50000 before showing 25% remaining. Has GM done something to reduce filter life?

 

What say U?

 

 

Lots of highway driving on that LML or something? 50K is nuts to push a fuel filter on any diesel IMO.

 

The L5P trucks are mounted under the truck now. Its mounted ahead of the fuel tank area. Cheaper than the spin on for the older trucks as well, only $46.54 TP1015/23304096.

Most highway. Changed filter when fuel minder hit 25%. Expect it would have gone over 60,000. Dealer or

GM thought it was excessive miles on filter. Traded after GM changed out the exhaust system a piece at a time. They tested fuel ,filters etc. but found nothing out of spec except the exhaust components

Changed fuel filter. Piece of cake, unscrew canister, remove filter and gasket, replace filter and gasket, screw on canister.

 

Turn on ignition for two minutes without starting. Self priming filter.

 

If all goes well it starts and keeps running.

 

It worked!!
