I use to go to Terribles for my Nissan Titan when I needed an oil change, tune up, etc. I one day tried Jiffy Lube instead and haven't gone back to Terribles since.
They give you a listing for different oil changes that can be done to your vehicle. I'm done with the $25 value change that was always offered around town and now feel completely satisfied with the high quality oil changes that Jiffy Lube has to offer.
I had them clean my fuel system and do a Pennzoil Premium change on my truck and the Titan ran better than it had in years. I was able to drive 2400 miles in a week and even after that it still ran smooth.
They do a very good job with computer diagnosis as well. They warned me my battery was getting old and should be replaced soon. Then, my battery died and that's why I'm sitting in their nice waiting room writing a review.
The attendants here don't feed you BS---they tell you exactly what's wrong, what could be future problems, and give very good recommendations.
