Hey guys, wondering what everyone's opinions and experiences on fuel cleaning additives are. I mean I use Nulon boost and clean, as at least I can feel the added octane boost, and at $15, it's not that bad. But I see people using the cheap $8 red injector cleaners as well as the $30+ "full fuel system cleaners" and makes me think, is there really any difference between them?

I wouldn't bother with them.
Run a tank of 98 every now and again, if you're not already doing so.
If there's a noticeable problem with the way the engine runs and there's a reason to suspect the injectors, then you'd get more benefit from having the injectors cleaned properly in an ultrasound bath.

I'm always going between 95 and 98 anyways (not fussy, I just fill up on w/e is in the isle I happen to drive in). Cars only done 50 000km, so I thought perhaps a quick clean would do it some good. The only time I have actually added an fuel additive was an octane booster for when I was going to the track. I just thought they might actually do something considering they make them and market them quite a bit.
every now and then i run a batch or liqui moly fuel system cleaner (gold can) through my car
get a really good fuel economy for about 4 tanks of fuel - no real noticeable performance differences - maybe slightly smoother
the nulon octane boost and clean or straight octane booster will help throttle response and revs are generally smoother - but it doesnt effect the fuel economy
i have used the cheaper ones like the red and blue bottles - but noticed no difference at all
always use 98 in the euro =)
upper engine cleaner by subaru is a great product - spray can that you spray into throttle body / intake manifold
gives the throttle plate, plenum, ports, valves and combustion chamber a good clean out =)
has anyone used nulon piston crown cleaner ? the foamy stuff you spray into the spark plug tube ?
Yes. It's good stuff. You can spray it in the intake manifold as well, but got to hold the throttle plate open.Quote:
