Title: Great, but MAKE SURE it will work with your car / truck!
Review: These used to work great when I was a child. I think the size of the dipstick sheath / receptacle has changed over the years. I had to essentially force the dipstick heater down into the oil chamber. This caused it to curve / bend and I'm still not sure it was down far enough into the oil.Consequently, I think I burned it out. But I can tell it would have worked just fine, if there'd been a better fit. So again, MAKE SURE it will work with your vehicle and if you have to force it or you don't think it's going down into the oil far enough, clean it off and return it before you damage it!
