I've always serviced my own cars because of poor quality work by most dealerships. Two years ago, I got tired of crawling under cars and decided to let the dealer do the servicing. The 5K and 10K mile service went well, but not so for the 15K. I found out the dealer used 5W-20 instead of 5w30 that was used on the two previous services. I have a couple of tappets that are quite noisy when the engine is cold and the heavier oil helps with the noise level. Also, I wasn't too happy about a puddle of oil on the garage floor after the servicing.
I had been thinking about switching to synthetic oil and extending the OCIs to 7.5K miles, so I bought a 5-quart jug of Pennzoil Ultra Platinum 5w30 and did the oil change. It was then that I found that the dealer had over-torqued the drain plug so much that the washer (aluminum) was deformed and had to be chiseled off the drain plug. The dealer must have used an air wrench to tighten the drain plug!
The oil change turned out to be more work than intended but I'm happy to report that the engine is noticeably quieter with the PUP 5w30 synthetic oil. Looks like I'm back in the oil change business. (LOL)
