After running a JLT passenger side oil separator with upgraded filter for nearly 3 years with great results, I decided to purchase the newly released 3.0 version for my GT500 with the intent of conducting a head-to-head comparison of the two filter systems on my car, just to see if JLT had indeed improved their product. Well, after 1000 street miles of testing with each, the results are in!!! I ran Amsoil Signature Series 0W-40 motor oil with the stock 192*F thermostat and a CFM baffled valve cover breather for the duration of comparison testing with no other changes to the car other than swapping out the oil separators.
With the previous version oil separator, I accumulated slightly less than ½ fluid ounce of oil. In the same number of miles and similar driving conditions, I accumulated slightly more than ½ fluid ounce of oil with the 3.0 version, which is that much more oil not being re-circulated through my supercharger and intercooler. Between the new multi-stage filter system and increased holding capacity, the JLT 3.0 oil separator is a win-win… and finish and fitment are perfect on my Whippled 2008!
