Synthetic is the wrong break in oil |

I just picked up my engine from the machine shop and quote the pamphlet of the Engine Rebuilders Association... http://www.aera.org/consumer/engbrkin.pdf
"The introduction of synthetic motor oils dates back to World War II and they are often described as the "oil of the future." Synthetic oils are man made, manufactured in a laboratory rather than pumped out of the ground and refined. They offer a variety of advantages over natural oils from better fuel economy, stability over a wide range of temperatures and operating conditions and longevity. However, the use of synthetic engine oils is not recommended for the "break-in" period. Its outstanding ability to reduce wear by virtually eliminating friction between moving components is not desirable for a "break-in" oil. Certain predictable amounts of friction are required for proper "break-in" of piston and piston rings. AERA does not recommend the use of synthetic engine oils for the first 5,000 miles of service. Thereafter it is up to the vehicle owner to weight the cost of more expensive synthetic motor oils, manufacturer's oil classification recommendations and drain intervals." |
