I have a 94 SC400 and want to know if fuel injection cleaners are safe to use and which one works best. Any suggestions out there?

I use the chevron brand because you can get it cheap from costco

I use nothing but Lucas! Lucas I'd say is the best, for any vehicle.

+1 for that stuff, i know a few people who swear by it. Don't need to use it as often as 2500 mi. I do it every time winter and summer comes around.

Seafoam is good, but not a full fledged injector cleaner. Injector Cleaner is more concentrated formula that seafoam is. I would use seafoam in the engine oil and intake manifold and then run that with chevron.

^ agreed you dont need it every 2500.

its a religious thing, hahaha
