I tried searching but didn't find the specific topic. if I'm using a PEA fuel additive cleaner, is it better to do it mostly on highway or city, both does it matter? I had used for mostly in the highway driving but now for some reason it seems like maybe better in the city I don't know
highway or city driving for adds.

personally i have used it when going on long highway trips but I don't think it matters either way
yeah I'm just going to throw it in there a couple hundred miles for the oil change no matter what driving I'm doing. I used to think it was better to do when on the highway because the wood stretcher out the fuel used have it in longer. But then I change my mind and thought maybe it was better to have it soak in more during city driving. guess something is better than nothing I was just looking for opinions really
I think that it's beneficial to ensure that the engine sees a variety of condition, is always warmed up fully, and ideally has as little ethanol as possible in the gasoline.
I would think that running the engine hard to be beneficial, especially when it comes to removing any deposits anywhere but in the injectors themselves.
I am always amazed at how little time most cars spend above even just the halfway to Redline point, based on computer readings it's typically on the order of a tenth if a percentile or less!
I have not done any kind of empirical study, but I have seen a strong correlation between the "aggressiveness" of driving the engine has seen and sludge build up, fuel dilution, injector clogging, and coked rings. The healthiest engines are those that get a spirited drive (say about an hour a weekend). Yet, people just don't want to believe that their attempt to save on gas isn't actually saving them money, it's setting them up for a number of big checks.
Then again, it's human nature to prioritize the present over the future, in fact we actually view future events/consequences as happening to almost a different person!
I know that I have spent years trying to get my mother to drive better, andfinally paid ffor her to attend a few BMW driving schools, and now she's gone to 7 HPDE on her own and got her blue card during her second time out. Needless to say, she understands that engines need to be driven, especially something like a BMW I6 designed for speeds higher than what US highways permit.

On my better car that I use for longer trips I usually fill up and add fuel additives right before leaving home that way I have good fresh gas and fuel system cleaner in the tank. The other cars are mainly used for local driving, trips of 100 mile or less so I just occasionally add an additive, usually no more than once a year. I never have had a problem with fuel system problems or injectors either way. One of my cars has over 500K miles and I've never had a fuel system related problem.

The cleaners PEA or solvent types like Berrymans perform better if run on short trips then left overnight especially the PEA ones.
It takes a few thousand cycles to bring the fuel injector coil up to temp, when shut off the treated fuel will sit in all the warm injectors and continue to clean.
The next trip anything loosened will go though the injector and the cleaning process will continue when the engine is turned off.
Determining what is clogging the injector is the most important part when choosing a cleaner.
If the engine ran well and sat for a long time with no stabilizer (common with seasonal equipment and summer vehicles) varnish from sour gas is the most likely culprit and a solvent based solution like Berrymans is best.
It is fast acting and can be run right through the system.
For performance that has dropped off gradually over time (most daily drivers) then hard deposit issues are suspect and a PEA solution is best and the longer it is in the system the better.
