It is true that an older engine that ran non synthetic oil may spring some leaks at the seals or gasket areas when you switch over to full synthetic. The reason for this is simple. Synthetic oil is clean.
Why does synthetic oil leak through the gasket?
Back then, the lubrication percentage was high, which caused the oil to leak through the engine gasket and other areas. Such incidents gave rise to the aforementioned myth. Ever since then, technology has advanced and many companies have worked hard to maintain the synthetic oil lubrication at optimal levels.
Is it easy to leak synthetic oil on a tractor?
Yes you knew it was in there! Synthetics are pure, clean and formulated (speaking for Amsoil only here) there for yes they can be easier to leak since they do not sludge up. Once a seal leaks sludge forms at the leak from the difference in temp, pressure, and a mix of other reasons. That sludge will help a bad seal or destroy it.
What are the risks of switching to synthetic oil in older cars?

Can a synthetic oil leak in an engine?
Myth #3: Synthetic engine oils can wear down seals in an engine and cause leaks. This is an often-cited myth.

But it might find an existing leak.
Is it safe to put synthetic oil in my older GM Truck?
If you drive your truck daily, the resiliency of synthetic oil makes it safe to push a few thousand miles past your suggested oil change mileage. Even if you drive only occasionally, it’s still a good idea to use synthetic oil because conventional oil will start to break down much earlier, even when not in use.
Older cars usually have to use conventional motor oil instead of synthetic motor oil. Switching to synthetic can cause engine leaks or engine damage.
What causes an oil leak in an engine?
An engine gasket is a seal that ensures that lubricants do not leak. When there is a break in the gasket, you will begin to lose vehicle fluids. In most cases, you will leak motor oil. The other less common causes of oil leaks are an oil pan leak, oil seals, or bad connections.
