Does switching between conventional and synthetic oils cause problems?

For years, drivers were warned that switching a vehicle to synthetic oil after years of conventional oil could lead to problems such as leaking around gaskets or even burning oil. The newest formulations of synthetic oil have done away with those concerns, and synthetic oil has proven superior in about every respect:


Conventional motor oil is prone to thin out at high temperatures and thicken in cold weather. Neither scenario is good, as it’s vital that motor oil make its way to the engine’s upper components (valves, camshaft, lifters, etc) within the first few seconds after startup. Synthetic oil is stable across a wide range of temperatures, and won’t thin out or become viscous.


Synthetic oil is more stable and uniform at the molecular level, with a greater shear strength. “Shear strength” refers to the oil’s ability to stand up under pressure—under extreme pressure, the molecules of conventional oil can literally be torn apart. This stability means that synthetic oil is a good choice for the extremely tight tolerances of modern engines.

Conventional oil, despite a high degree of refining, will still contain impurities like paraffin molecules. Synthetic oil is 100 percent pure, and its enhanced detergent additives can keep the engine cleaner—that’s why synthetic oil can easily go 8-10,000 miles between oil changes.


Your engine needs gasoline, air, and spark to run—but it also needs motor oil to coat and protect its moving parts against excessive wear. You might have heard your dad say years ago to “always remember to have your oil changed regularly,” and to this day it’s still true. Nothing is more crucial to engine longevity than proper lubrication and regular oil changes that will prevent a buildup of sludge and carbon in the engine.

Most street cars come from the factory with either wheel studs or wheel bolts. (There are also center-lock wheels, but those are usually reserved for top-tier race cars and high-end performance street cars.) So what exactly is the difference? Team O’Neil Rally School expert Wyatt Knox put together a quick explainer video showing you the advantages and disadvantages of using bolts or studs, whether you’re racing your car or just daily-driving it.


Wheel bolts are standard on many German-built cars, and use a threaded stem attached to a tapered head that matches to the wheel insert. The bolt goes from the wheel, through the brake rotor hat, straight into the hub, locking everything in place. The difficulty with bolts is, the brake rotors are free to rotate while the wheel is off since there’s no stud holding them in place. That means you have to realign the rotor with the hub inserts (along with the wheel) when you’re putting everything back together.


Wheel studs and lugs are different in that, instead of using a single piece that screws into the hub, the studs are mounted in the hub, and stick out beyond the brake rotor hat. The wheels are mounted using lugs, which are screwed onto the stud. This makes it easier to mount tires without having to worry about lining everything up. Knox does warn, however, that having studs that are too long may leave you with issues should one of them bend or break.
