Turbo failure due to contaminated lube oil is caused by:

-poor oil filter maintenance
-oil filter bypass ( cold starting/clogged filters)
-dirt entering the crankcase by inlet air (bad air filter)


Before you spend money on a lifetime filter, think about Turbo Awareness Behaviors.
-Let the engine idle at startup, a turbo is a supplemental device and usually the last device which receives oil.
-let the engine reach operating temperatures, before you hit the pedal. Your turbo will love you for that behavior.
- before shutdown let your engine idle, to cool down! typical mistake to avoid: stop for refueling on the interstate.If you know you have to refuel, go easy before you leave the interstate.

The most important thing: Change the oil, when you are supposed to do! You have to keep the concentration of the particles smaller than 30 µm as low as possible.

 

hmmm

 

IMO there is NO SUCH THING as a lifetime filter. Filters and oil are cheap when compared to engines and transmissions.

 

Very True !!! But , you do not have to change every 3 k either .... On a diesel in city (7 K ) and 75% or more highway ( 10 K ) on my N14 cummins I go (15 K ) @ 75% highway !!!
