WHO POCKETS FROM YOUR STUPIDITY. they would tell you that you need to change it every 2.5 seconds if they could get away with it without someone FINALLY raising a suspicious eyebrow lol. ****, i remember growing up it used to be every 10k miles, sometimes even 15. now its 6-7500. I have actually tested this. I ran royal purple in my subi for 4 years and just swapped out K&N filters "its a bi7ch" and after all that time the oil was still as clean as ever. although I also have a RE magnet drain plug but I would never find anything on it so it ether doesn't work or the oil is doing its job.
switching from conventional to synth doesn't matter. switching from synth to conventional does. and synth eating seals ...... thats long in the past, additives have since gotten so much better. just dont put that high mileage **** in, it has weird detergents and other crap in it to fight "engine buildup"
if you dont believe me, theres plenty of googling to be done. by all means second check.

sooooooooooooooooooooooo you're saying i can leave the same 6 quarts in my Z for the lifetime of the car but just change the filter?
i would first like to say that's retarded. have you ever seen oil at the time of change? mine usually looks like it needs it and also if you run a Z hard without a oil cooler theres a good chance you may have burned off some oil as well no matter if its conventional or full syn.
also i would like to see you drop the filter off of an oil pan that is full and put a new one on as the oil in it dumps out on you
sadly this all made sense when i saw you owned a "subie"
