Yes , for this car it is a thing of the past, but I'm willing to bet, with one out of the thousands of types of vehicles made in the world , someone continues to advocate using the passe method for breaking in an engine. And just think, the cars made way back when definitely lasted allot longer than they do now a days.
I still wish I had my 1985 ,(I think ) Buick Century. Bought it for $900 dollars and ran it until the wheels feel off. Never had any major engine problems. Those where the days. .
