legend dan! let me know how you go
sorry, haven't kept an eye on this thread over the last couple of days.
i checked quantities for qualifying for a group disount with performancelub - 48 quarts...
not sure if we can get that amount of interest.
last time i bought oil i spent abut $160 i think getting 5 quarts of royal purple and 5 of redline. shipping for the extra 5 quarts (10 total) only added about $3 to the original $20 i would've paid for shipping 5 quarts.
i think if you change your oil every ~5000kms, and don't hammer your car every weekend or whatever, you can definitely stick with mid-range oil without really missing out on anything.
i'm using redline for now cos i'm not sure what used to be used in my engine, and i figure a few cycles of redline will help clean the system, and then i'll probably drop back to a cheaper option.
