Adding Additives/cleaners (1 Viewer)

[1991LandCruiser]

Are there any benefits, and is it worth the expense by adding the various available 'additives' for the Injectors/gas/oil etc to an aged vehicle
I would not want to add something to clean the soot etc from my valves if it makes my engine sound like a commune of skeletons having an orgy
If yes, can you recommend any?

Seafoam is pretty good stuff!

Need hard data

Been much discussion about Seafoam, do a forum search. My mechanic recommends Chemtool B-12 every few tankfuls.

You will likely find many opinions on this topic. What would be nice is someone who is a good enough mechanic to deal with replacing fuel injectors who has tried some of the injector cleaners out there and seen for himself (or herself) what works.

Any of you 2 and 3 mechanics have any advice?

Not of heard of seafoam, but will do a forum search, thanks.

Sea foam is effective, fun and non environmentally safe.
I use it once a year or so. You tube it.

i use the bg44k occasionally. supposedly, it was part of toyotas regimen too.

I use stp fuel system cleaner every few tanks. I cant say I feel an in your pants difference but from a prior bmw m3 I had when I put the stuff in you can feel a noticable difference compared to a tank with no treatment. So I feel it has to be doing something.

BG makes very good oil additive. I am sure the rest of their products are just as good. I used to use the oil additive in work trucks.

There was a highly-highly detailed thread quite some time ago about a slew of additives and their respective chemicals and how they effect various rubber/silicone parts of the cruisers fuel line. My take from it was that redline fuel injector cleaner and bk44 were two of the best for injectors yet they still did eat at certain parst of the fuel lines/injector parts. IIRC- they were to be used sparingly and you were doing more harm than good if used too often. Im not exactly sure what the service life of the injectors are tho????? which would probably help coming up with something like 'once every 20k miles'/etc.??

I have used seafoam and many recommend it, but I can't say how good it works. I have used B-12 chemtool to clean pistons and throttle plates and it works great. We use BG air intake cleaner in a pressure can rig and 44k at work(Toyota dealer). Many people swear by the 44k so I will likely try it since I get it close to cost.

I used Auto-RX and it helped my low oil pressure. Couldn't tell any difference with Seafoam, but most disagree.

 

[jakesiar]

I have used AutoRX as well (engine and tranny). Worked for me...

 

[TeeDiggs]

Where do you all usually find 44k? I have casually looked before and don't see it amongst others.

 

[jakesiar]

Go to their site and look for resellers/distributors. The cost is around $25. I have used RedLine Fuel System Cleaner and I felt it worked just as well as BG44 and the cost where I get it is $9...

What is the specific problem you HAVE? To me, anything more than a bottle of Techron in the tank every few K is a problem waiting to happen if used wrong.

Say you have a motor full of sludged oil from a previous owner - you toss in Seafoam (I've used it working a used carlot as a kid) - all of a sudden you now have major crap floating in the oil & hopefully captured in the filter, or it plugs the filter & starves the motor of oil & fries the rings to the block in no time flat. (I did just that with a later 80's turbo Mazda RX7 on the lot). Granted, it was a Wankle Rotary motor (so I more melted the lobes to the block than say conventional rings), but that's just my example.

After that, I was hesitant to use anything, unless the was a specific problem to be cured. You know - why go rocking a boat that isn't leaky? That's just my POV.
