not true, at least not in my case.

Using 15w-50 Mobil 1 for 9 years, nearly 40,000 miles. No measurable wear on rod or main bearing checked recently. Piston/cylinder clearance unchanged. Car started and ran 4 to 7 times a week, minimum 30 miles, usually more. Longest trip 1700 miles over a 3 day period.

I do agree that it doesn't seem right that someone would set up a high perfmance engine, a street engine that is, with loose bearings.

Z.

p.s. no leaks either
