This weekend I changed my oil from standard 15-40 to shell Rotella 5w-40 full synthetic.
Right from the start I notices my engine was much quieter. After driving about 100 miles, I noticed my milage had gone up by almost 2.5 MPG. That was with the dooohiiiky in the roof, however if this looks good after a few tanks..... I'm sold! I'll never go back to regular oil again. I did have it done at Wal-Mart for about $75.00.
I did however have to make them do it over again because they put regular Rotella in the first time. Make sure they use the blue bottles not white ones. They weren't to happy about having to drain 15qts of new oil. Oh-Well the techs should read the work order first.

Just thought you all would like to know.

I just changed my brand with the last two oil changes. I didn't go syn, I've been using 15/40 Rotella dino exclusively since new. 120,000 miles at last change, I have noticed that I was losing some oil between changes and I had a few drops in the driveway. I was probably adding two quarts in the 5,000 miles between oil changes. I switched to Valvoline diesel oil 15/40 and didn't have to add any over the 5,000 miles between changes. Don't know why but I am waiting to see if this oil change works out the same. I have thought about switching to syn but couldn't justify the cost, I don't want to go extended mileage between changes.
