Latest study on conventional vs synthetic oils

I found this of interest:

In the study, AAA found that "synthetic engine oils performed an average of 47 percent better than conventional oils in a variety of industry-standard tests,” the organization's managing director of Automotive Engineering and Repair, John Nielsen, said in a statement.

“With its superior resistance to deterioration, AAA’s findings indicate that synthetic oil is particularly beneficial to newer vehicles with turbo-charged engines and for vehicles that frequently drive in stop-and-go traffic, tow heavy loads or operate in extreme hot or cold conditions.”

But you aren't going to put yourself in the poorhouse if you flip for the synthetic, either: these oils add an average of only $64 per year to vehicle operation costs, a bit less than twice as much as conventional oil.

 

1974 called... they want their oil study back.
