Key Differences

Seafoam, in addition to your gas tank, can be placed in with your oil and still work just as effectively as if it were poured into your vehicle’s gas tank.

However, for the best results, it is recommended that you pour Seafoam directly into your vehicle’s vacuum line so that the treatment can reach the vehicle’s cylinders directly.

To get the best results from Lucas fuel injector cleaner, it is recommended that you pour the cleaner into your gas tank when your tank is near empty so that the injector cleaner can stay potent and undiluted.

For readers with vehicles that use diesel gas, an additional attribute of the Lucas fuel injector cleaner is that it can neutralize the effects of any low-sulfur diesel gas that you may unintentionally fill your tank up with.

As with diesel engines, Lucas fuel injector cleaner has superb compatibility with a wide range of vehicles.
