Bests & Worsts Reviews from Amazon

I was lucky enough to happen upon a cream-puff BMW 3 series, garaged, one owner, rarely driven in last 7 years. I wondered if I was buying a ticking time bomb, since it sat for so long. Had the dealership check it, change the oil and brake fluids, air filters, etc. But my local BWM-trained mechanic told me to put Chevron Techron in the gas tank before driving it around to clear the fuel line of sediment and gunk. I did so, drove off the stale gas, refueled and a month later, added another quart. It's running like a top. So glad I got this advice.
