Remember that is just an opinion regarding synthetic oil. It is an old wives tale that synthetic oil causes leaks. It might reveal them. However the best thing you can do for any car is use full synthetic from the start, and if it shows a leak, fix it. I use nothing but synthetic on all of my engines, none of which is less than 120,000 miles, and they run great. They had at least 50,000 when I started putting it in.
