The shop I use hit me for $78 on a full synthetic change.
I don't blink. I swing by and need something welded for the snow plow on my Jeep, done. No charge. Wife drives me there to get my vehicle and they see she is due for an inspection, done. No charge. Tell them my brakes feel spongey in my car. They jump on it for a quick bleed down and find one of my bleeder valves was broken off some time back. Bam. Pull the caliper, easy out the bleeder, get a new one in bench bleed it, bleed the system back. No charge. Want my own parts I bought with no markup installed? Bring it.
A good service shop is hard to find. I'll pay a bit of a premium for an oil change.
