CONCERNING BATTERIES,
I've never had any luck with a Delco (GM), Exide I understand may be going Chapter 11 soon and DieHards really only good for 2-3 years. Once knew a guy that worked at Sears and he had them in his car but would intenionally short them out just before their one year mark to get a new one free as he also didn't trust them!

Interstate is the way to go now as they just took over the Optima brand of the six round jell-cell that doesn't need vents and won't rust your car.

Bosch and Varta both make MB batteries but I won't change one out because a 'dealer' says it's the wrong one and works OK. Get a second opinion, better yet get a load check done before dumping a good battery.
