more oil = longer time to cool and fewer times cycled through the system between oil changes. Both help greatly.

 

porsches and benz always have pretty large capacities too, my 98 e420 holds 8-9 quarts as does the cayenne turbo.... i was suprised at the audis small capacity....

 

Just the longitude 1.8t's have that problem. The transverse cars all hold 5qrts with the small filter and ~5.5qrts with the large filter. If you want even more oil, the Napa Big Kahuna (#1333) is way larger than the Audi large filter.

 

v8 s4's hold 11 quarts if i remember correctly
