well on an LA1 engine that doesnt require a large amount of oil capacity (4.5qt is not alot). increasing to 5 quarts will have an influence.....minimal but definitely an influence.

theres quite a few engines that are far smaller than 3.4Liters and require alot more oil. so if you think about an engine such as a 4.2 fsi v8, requiring 11 qts of oil and you over filling it with .5qts, there wont be nearly as much of an noticeable affect compared to some engine that might require 3.5 quarts and over filling .5qts.

basically the larger the oil capacity the less noticeable a small over fill will be, but the smaller a oil capacity the more noticeable a small over fill would be.


now when i was running that 3800 oil filter i was advised to increase capacity by .5 qts, if it was only supposed to be increased by .25qts then that could of been my fault and that would portray a more apparent drag on the engine.
