Which is cheaper and more effective? (Oil Change)

[BLLDOGG]

something to think about if you decide to ever have someone change your oil. my local walmarts lifts allhave broken safty locks.

the 3.8 takes 4.5 quarts.

i've got two sad stories about "quick lube" stores:

1. my own oil pan was cross-threaded using an impact wrench and a little too much **** diesel, but they didn't bother to tell me and i didn't find out until the dreaded "this is way too easy to turn" feeling when i did it myself the next time. i hope my filter caught all the shards floating around in there... :(

2. my old boss/school friend took her 240 to one of those joints to have her oil changed. a day later she comes into work saying "my car's engine is making metal on metal noises, what could it be?" and i thought it was just a heat shield or something down there, but we checked the oil during some down time anyway... i don't know if it was completely empty of oil or not, but nothing registered on the dipstick. changed the filter, though.

hence, i always do maintenance myself.
