Modern Vespa

I was at autozone the other day checking out and I saw a bottle of some fuel injector cleaner on sale for 2 bucks and it made me wonder if anyone ever adds fuel injector cleaner like b-12 or something to the gas of their Vespa?

I add Seafoam to my ET4, but I've never had to add any injector cleaner on the BV500. Seafoam isn't going to clear out a clogged idle jet, I had to open up the carb and clean it out myself, but it sure was clean when I got in there.

I've used Chevron fuel injection cleaner in every fuel injected motorcycle & scooter that I've owned in the last eight or nine years. I've also used it in my fuel injected cars for around twenty years or more. You only need to use it every couple of thousand miles. I have never had a clogged injector on any vehicle. The good experience that I had with using it in my automobiles prompted me to use it in my bikes.

I can't speak of the effectiveness of using the "off-brands" or "bargain-priced" brands but I've read where some of them don't work. The Chevron fuel injector cleaner is a proven product and used by many people. For the last few years, I have been able to buy it at Costco at a much better price than I was paying for it at auto parts stores or gas stations.

Does fuel injector cleaner have an open bottle no-shelf life, like brake fluid?

I just walked out to the garage and read the label on the Chevron ProGuard Fuel Injector Cleaner. It doesn't have any warnings regarding shelf life. Whenever I open a bottle to use in a motorcycle or scooter, I use the appropriate amount and put the rest of it in one of my cars.

Never have. The gas I use (Chevron / Techron) allegedly has cleaning agents in it, but I don't really know if it does any good or not. Never had an issue, though.

If your scooter has at least three thousand miles on the clock, it probably has some gunk in the injector. if you put some Chevron Pro-Guard in it and check your gas mileage for the next few fill ups, you will probably see an increase in gas mileage due to the injectors being cleaned out. Same thing with your cars.

+1, I try to use only Cheveron super unleaded. I guess no need to refer to it as unleaded anymore, kinda pointless.

Dropped one o' these in:



And now my 250 can drop a Schumacher Ferrari!




(I use Shell, like everyone else in my cars, put a little in the tank every once in a while)

I try to fill exclusively with Chevron 91 around here, and as such, don't feel the need to add detergents to my fuel. That said, Seafoam is the only product I implicity trust 100% in any of my vehicles, and I'd add it to the Vespa in a second if I felt it warranted it.

Simply use any brand of gasoline that meets the Top Tier specification. That's what it's for.

+1 on the SeaFoam. Don't know about how well it works with injectors, but it sure seems to dissolve the gunk in carburetor idle circuits.

[quote="Silver Streak"] How much do you use and how frequently?

(tried searching, but got toooooooo many hits to wade through. this seafoam stuff comes highly, and frequently recommended)

thanks!

send me your money and I will "clean" your injector for you.

Save your money

Since I don't ride the ET4 very much these days, I use SeaFoam as a fuel stabilizer. Apparently, it will stabilize fuel for up to two years. But like I said in a previous post, it definitely cleaned out the carb. It can also be used as an oil additive. Just follow the directions.
