OT: Auto Fuel Injector Cleaners

With these two actions, your fuel injection system should stay reasonably clean.

Me too. I had a snowblower that would not start - cleaned carb, new gas, new plug, filter etc. Sea foam to the rescue. I have never thought to use it in car engines - makes sense. Will now. Thanks.

Diesel Service treatment every tankful 9 months out of the year. Winter Treatment when the temps get close to freezing. Seems to help keep the high pressure fuel pump lubricated. Also protects against out of season spec diesel fuel from gelling in cold weather...

For the TDi, of course.

For my gas motor, just top tier gasoline, no additives. I trust Mobil or Shell to figure it out.

i’ve used lucas and seafoam.

i haven’t noticed any performance differences

+1 for Seafoam

We used Sea Foam in our boat which had an injected 454ci Chevy and 100 gallon tank. We had no problem with stale gas some of which had to be several months old.

Not sure what the formula is these days, but my grandpa has sworn by that stuff since probably 30 years ago when he was having issues with his motor either stumbling, stalling, or something else(i dont remember exactly), but he mechanic at the time recommended that for it and it cleared the issue right up for him.

But yeah, it could be that things have changed over the years and the amount of PEA is very little now.

You are spot on about PEA. Polyetheramine is a top-tier detergent proven to be the best at cleaning fuel systems.

Manufacturers don't have to give the exact amount of PEA in their products, but Redline SI-1, Gumout Regane, and Amsoil PI have the highest reported percentage of PEA in them. In my gas cars I use a bottle of Redline Si-1 every 5k miles.

What type of vehicle/engine.

I always add a bottle of Gumout All-In-One Fuel System Cleaner to my tank during oil changes... Can't say I notice a difference, but I don't usually have any problems either... I tend to keep my cars 10+ years and I've been doing this since high school auto shop in the '70's.

You might get some benefit from using a fuel injector cleaner but it would be marginal at best if you use top tier gasoline. If your vehicle(s) have direct injection engine(s) I wouldn't bother with fuel injection cleaners. Direct injection systems use higher fuel pressures and that should keep the injectors pretty clean for some time.

Best to talk to your trusted Subi mechanic.

Owned my '87 Toyota 22RE EFI since new, never used any injector cleaner, never let the gas get stale, always bought the cheapest gas I could find (which usually means its the freshest). Still runs as perfect and clean at 253K as it did when new. I think those cleaners are a gimmick.

I agree completely. Until she runs rough then maybe it can be proved out otherwise don't bother.

Gas powered anything likes to be run daily. More so with the 10% ethanol in the gas.
