Fuel Additives w/EAT

[94_e34_525i]

Does anyone know if I can use fuel additives with my chip? Will it affect my engine in a harmful way? I'm just curious. Thanks

Might you be more specific? The EAT chip requires 91+ octane fuel. Beyond that it doesn't care.

IMO, no problem. I have used at least Techron, Regane, Lucas UCL and FP60 with no issues. The last two you add to every tank. when I used fp60, my plugs after 30,000 miles looked excellent, just worn. I ran out of fp60 or I would be using it now.
