There are quite a few myths pertaining to automotive engine oils, especially the synthetic oils. In order to help set things straight, we’ve addressed and debunked a lot of the common synthetic oil myths in your mind.
A common myth is synthetic motor oil a ‘fake’ oil.
Synthetic motor oils are not fake. They are derived from crude oil, natural gas, or other chemical feed materials. However, as a general rule, they use more extensively processed, higher quality base oils than conventional motor oils. Synthetic oils also use different additives than conventional oils that are designed for extra wear protection and higher stability to temperature and shear.
Another myth is synthetic motor oil bad for engine seals. Synthetic motor oil will not cause any damage to engine seals.
The most popular myth is synthetic oil causes cars to use more oil? It is wrong. synthetic oils do not cause an engine to use more oil.
Does Synthetic oil create more sludge? It’s not true also. Valvoline synthetics include extra detergents to help clean an engine and reduce the risk of sludge.
Are synthetic oils too thin and can create blow-by and oil burn-off in older cars?
Synthetic motor oils don’t affect seals and won’t be the cause of blow-by or oil burn-off in an older engine. Just like conventional motor oil, synthetic oils have a specific viscosity grade. However, quality synthetic motor oil contains extra lubrication additives to make the oil stronger and provide higher heat dissipation.
You’ve already used synthetic motor oil. And, you can’t switch to conventional motor oil. It is not true. You don’t need to be worried. For your information, synthetic and conventional oils both are compatible, so it is not harmful if you decide to switch.
