Fuel additives?

If you are using TopTierGas.com gasoline, nothing is needed as detergents are added.
If you are using non TopTier, then a few tanks of TopTier periodically or adding some Techron once on a while might be good.

 

Fine to use fuel cleaner.

Techron is highly recommended. Also good to high load the injectors for more effective cleaning.

 

Can you clarify, in laymen terms?

 

Meaning WOT (Wide open throttle) where your injector is working on higher load.

 

Answer: NONE.

Except a dose of Techron every 6 months or so; minimum: with each oil change.
But that does NOT mean what the dealer puts in at 3X the price for exactly the same thing.

AND.....I think you should do that regardless of what brand of fuel you use.
I just don't trust the people in the distribution chain to really DO what they are supposed to do.

 

My wife just took the grand kids to school this morning, just a once in a while thing. One of the schools is up what I like to call "heartbreak hill", 2.1 kilometers of unrelenting steep climb (157 meters). That 13.37% slope on average.

I put in a does of (Canadian Tire) injector cleaner with the last fill up, so I guess a run like that would help.

Off-topic: you have to wonder, when community planners locate vital infrastructure, hospitals, schools, do they pay any attention to elevation differences?? There are hundreds of cars daily hauling butt up this hill, thanks to their decision.

 

Injectors don't work like a carb.
Keeping the injector open a thousandth of a second longer isn't likely to make the solvent work any better.
