You can. I would not expect fabulous results. I have a deep distrust of anything with the Lucas name.
When I want an injector-cleaner-in-a-bottle, I buy Chevron Techron. I drop a 20-oz bottle in the gas tank at every oil change (6K--13K intervals.) It's fairly often sold as 2-for-1 at O'Reilleys.
I use to think sea foam was a good product. I soaked a set of varnished injectors in sea foam for a week almost none of the varnish came loose. I also tryied cleaning carbon off a piston didn't work very well fogging oil worked much better. Just my two cents .
No additive is really going to fix injectors that I've ever found. As far as preventative maintenance, I do run seafoam through all my vehicles regularly. It helps my carbed bikes especially with preventing the pilot jets from clogging up from crappy Cali gas.
Not really looking for magic but the injectors do not seem to have that really nice cone spray I am used to seeing and thought I would try an additive first.
I will do some research on how to manually clean them.
If anyone has advice in that area it would be much appreciated.
At the shop I use an OTC 7448 canister that hooks onto a schrader valve and uses concentrated cleaner to do the job. Basically you disable the factory fuel pump and your car runs off of the concentrate and it cleans the injectors. Most mechanics offer this service and it is done it's usually done every 10k miles or so.
You can buy the kit and do it yourself, but you'd be looking at around $200 to buy all the stuff. Personally I run Royal Purple injector cleaner in all my DD every oil change and all the time in my mower and stuff that doesnt see a lot of use.

That's exactly my impression. Seafoam wouldn't clean smoke and soot from the outside of a set of motorcycle carbs that had been in a garage fire. I'm told it works pretty well to stabilize gasoline that's going to be stored over a winter.

Every 10K? Maybe every 50K. Most folks don't buy that service...ever.
The REAL solution to dirty injectors is to buy gasoline that's advertised as "Top Tier". Top Tier gasoline--regular, premium, or super-premium octane rating--has additional detergent compared to EPA minimums. You use Top Tier fuel, you'll never have to clean the injectors--they'll never get "dirty".
I never believed the hype with the "Top tier" gas, until I started running it. My old 88 k1500 (tbi 4.3) was bad in its older life of having some spark knock on anything less then midgrade gas. A new QT (QuikTrip) was built and they are top tier. Could run regular 87 without issues. Swap to other places and it would ping a little. But with the QT gas, it ran just fine. Coworker had an F150 doing the same thing and he didn't believe me until he tried it. Same results, no ping with top tier gas.

Exactly. The only reason we have the system is for vehicles that have been neglected. The majority of the business I see is rebuilt wrecked vehicles (1/2 ton up pickups) that are sold into fleet service for some local businesses.
We have been reconditioning a bunch of flood trucks out of the south that are going to a roofing company and the fuel systems in these things are nasty. We use the OTC can to see if the trucks will run without having to clean out the tank.

Yup.

Damn fine strategy. I bet it saves a heap of money on the vehicles that won't run.
I used the basic "Gum Out" injector cleaner following there instructions and 3/4 of a tank later and the injectors are spraying like they should.
Could be just my imagination but I gunned it getting on the freeway and could have swarn I heard a little pop and then and the injector made a heavy spray noise then disappeared.
Could have just dislodged something from the jet.
I thought the car was running well before but it seems to have a smother feel to the acceleration now.
Totally worth the few dollars it cost me.

glad to hear it worked out for you.
my son had a 5.7, TBI truck that was spraying funny. we put a bottle of the gum out cleaner and some premium gas in it. the next day it was running better and the spray pattern looked real good. i became convinced of they're product. it's fairly cheap priced too.
