I've always done my own, and now will continue to do so with my new Jeep. Having to use Pennzoil Platinum Full Synthetic brings up a cost issue I never paid much attention to before.
The HEMI takes 7 quarts. My local Wal-Mart sells 5 quart jugs of the stuff for $27.17. That comes to $5.43 a quart. They also have it in 1 quart bottles, but for $7.47 a quart. So I'm just going to buy a couple of the 5 quart jugs, and one of these:
Lumax Silver 2 Quart Galvanized Measure Can with Flex Spout
Then I'll just keep the remaining 3 quarts left over for the next oil change. I can't see paying another $4 bucks for the convince of quart size bottles..... But then again, I'm cheap. Wal-Mart has Mopar oil filters for around $6 bucks as well. So I'm looking at around $44.00+ tax for an oil change. Not too bad. I'm finding none of the chain auto parts stores can even come close to what Wal-Mart charges for top of the line synthetic oil and filters. They're like 30% to 40% more.
