I do my oil changes for $17-$20. LOL! I get the 5Qt jugs of Pennzoil Platinum on the rebate special for about $11 each, then a SuperTech spin-on filter for $3. Or, when no rebates, it's SuperTech 5W-30 Full Synthetic for $14. Then I just pour in a 1 Qt Conventional 5W30 ($3) to make it 6 Qts. So it's a 5/6 full-synthetic, 1/6 dino "blended" oil. Good enough!$90!! That would be another reason I do my own oil changes. I use AC delco full synthetic and AC delco filter so I'm about $40 (CAD) in for a change and 30 minutes of my time.
