Should PEA or PIBA be used for fuel-injected cars?

[DiEzra]

Both fuel-injected and direct-injected engines use PEA. The following are the differences between PIBA and PEA: 1. Composition: Fuel additives with polyisobutylene amine (PIBA) as the main component focus on cleaning carbon deposits in the fuel system, injectors, and intake valves. However, they cannot effectively remove carbon deposits formed under high temperatures. They are only suitable for port fuel injection engines using unleaded gasoline and should not be used in direct-injection engines. 2. Cleaning performance: If the engine uses ethanol gasoline with a lower ignition point, it may wash carbon deposits from the fuel system into the combustion chamber, thereby increasing carbon buildup in the cylinder. Therefore, fuel additives with polyisobutylene amine (PIBA) as the main component can be considered as maintenance-type fuel additives.
