Official Redline SI-1 thread.

Do you get any smoke on startup when you do this? I get a little smoke at cold start when I do. Clears itself up when I refill the tank though. And I too notice idle and driving improvement.

Zero cold start smoke whatsoever.
Just a happy HEMI.

Freaked me out the first time I saw it. Checked everything to make sure I wasn't burning oil. 100% positive it was SI1 mixed in high concentration. My truck is straight piped though, wonder if thats why I see it.

Interesting, you know sea foam does this because it is super concentrated 100% solvent right on piston tops. Burns that carbon off real good, never heard of this with si-1. It really brings up a great question, because if anything else all of the info in this thread proves concentration level does matter. If I have an opinion on this, I would want to do a long trip after or during this strategy, get that catalytic converter real hot and get all that ash off that. I would get a boroscope and put it down a plug hole, see what's up.

It's hard to know what the sweet spot is, but I would say at a minimum I would want a full bottle of si-1 per full tank, and then possibly using that bottle in a half tank do present great possibilities. Or even in a quarter tank. Thank for all the guys bring this up, worth considering. IMO this white smoke is a good sign, maybe not for catalytic converter but Good for cleaning carbon.

Decided to take a look inside my 300's cylinders today,but i'm not putor literate enough to get pic's off my boroscope onto here. After a bottle of CRC's 1 stop cleaner and a bottle of SI-1 ,the outer edges of the pistons towards the ring lands are definitely cleaner then they were last fall. The center of the pistons don't really show much differance,but it's tough to gauge the thickness of piston top carbon build-up,they might have less carbon then i think,but with-out pulling the engine apart it's only a guess on my part. The stuff does clean the carbon on the outer edges of the pistons though,and probably knocks a bit of carbon off the top ring land. I haven't really noticed any differance in injector noise,they don't seem to be any quieter then they were,but then again,they aren't any noisier either.
Whether it's a cure all for fuel system issues,i'm not gonna coment on,but then again,i also don't think it hurts anything either. If you have noisy injectors it's probably worth it to run a couple bottles of the SI-1 through the system,and see if it helps.
The stuff appears to work,maybe not as much as i was expecting,but i only ran one bottle of each through the system,maybe if i'd of bulked it up to 2 bottles of each per tankful of fuel,i might have seen more results.

Does anyone happen to know the shelf life of redline sI-1?I'm looking to stock up.Also,while I'm asking,whats the shelf life of lubegard?I like being stocked up. Must be an old guy thing.ha ha.

 

[Burla]

good question, I do not know, and now that dave is gone i wouldnt know who to ask.

 

[HEMIMANN]

If Red Line left their contact form up on their website you could send your question and see if or who responds.

Weren't they going to move their OG California operation somewhere per owner Phillips-Conoco?

 

[HEMIMANN]

Sure as $hit, on the way home from hunting property yesterday, we re-routed to evade the storms and there wasn't a single Top Tier branded fuel station for 250 miles.

Kwik Trip took over most of the region, and of course dumped Top Tier Certification during the pandemic and never went back.

Hence, I now carry a measure bottle of SI-1 in the truck - added my 1 ounce per 15 gallons gas - wahlah - instant Top Tier detergent dosage.

While Motor Oil doesn't need any extra additives, what about your fuel? Can adding a bottle of Chevron Techron actually make your fuel better? AAA paid an in...

Good watch here, Brother & thanks for sharing it!

I dump in 2 bottles of SI-1 in a tank full of premium (well...I always run premium...lol - however, I use Petro Canada 94 or Shell 93 when I do these treatments as opposed to just using 91 at all other times) and run my HEMI as she likes it... (good and hard!!!)

Finish that tank and then another tank full of 94 or 93 until empty.... (then it's OCI time)...

I can notice at about 15,000km's or so after my last SI-1 treatment that my idling and responsiveness takes a mild hit. My HEMI in my 19' was similar as well.

I'm just about 500km's away from my next OCI, and it's been about 20,000km's since my last SI-1 treatment regime and I can really feel my HEMI needing a fuel system treatment.

Hopefully it won't skew my lab results too much, but I needed to do a two bottle treatment now as it's oil & filter change time next week.

Never any white smoke on cold start ups, winter or summer, and using two bottles of SI-1.

A lot of his videos have great information IMO. MOST (not all) of the time supported by “science” and facts.

He has another great one on base oils, particularly on “Group 5” oils.

 

[Burla]

Yes, that is a thing, dont expect si-1 to be like hemi honey, it is a different immediate feeling. I do not know the why, maybe the lubricating oils? Maybe those as a carrier is why it is more effective? I would say adding two bottles is aggressive, I might try one and see. I'm not saying I don't like it, because I do like that. But before doing that I would invest on seeing how it is paying me back, get a bororscope and check pistons. Not the first time we heard si-1 engine not as responsive on heavy dose. Will go back to normal as you fill gas back in.

Chevron cheapened Techron by switching from the PEA they invented to cheaper, less effective polyisobutylene amine (PIBA). Look at the SDS's.

I investigated this some years back and reported. Techron isn't Techron anymore. Because cheap = good (for executive bonuses).

Use Red Line Sl-1. Done.

Yup. I only use S-1 as well.

I 100% think you are right. The carrier oils are probably why. Especially @ 2 bottles when the directions say 1 bottle. Octane related? Maybe, maybe not. Cant look past that though

I know in the new diesels with the high-pressure injectors/fuel system, if you’re doing an old-school additive like ATF or 2-stroke oil its actually a very bad idea for them because the size of the oil molecules do not like going through the HP injectors.

I’m not smart enough to know if gasoline injectors are high pressure enough to be affected by two bottles of S1 but it’s just a thought.

I hear you and @Burla on the 2-bottle treatment, and I appreciate both your inputs!

I do have the larger 32-gallon tank and only do this heavy dose treatment a max of 2 times per year. It has always served me well and never caused me any issues with my engines. I can feel it cleaning, per se..lol.

I'll have a Blackstone lab report soon enough and it will have 10,000km's of use and 2-bottles of SI-1 about 500Km's or so before the oil & filter change. Let's see what that come back like.

Gas injectors are pretty free flowing,as they only operate at 68 psi,the pintle and seat on a gas injector would take alot to plug,but the screens might be a differant issue,but even the screens aren't all that tight of a weavve,and should handle a fair sized particle.
I ran a few bottles of injector cleaner through my 300 awhile ago,then pulled the injectors and bench cleaned them about a 1,000 miles after the fuel system cleaners,and the injectors are noticably quieter after the bench cleaning.

Injector cleaning

Supposed to go cold and snow for the next 10 days,so i figured it was a good time to pull the injectors and give them a cleaning.Got them soaking in injector cleaner,where i'll probably leave them for a couple days before using some carb and choke cleaner to wash them out using my old homemade...

This is what redline says...

Cleans injectors, carburetors, valve and combustion chamber deposits with a concentrated blend of the most powerful high-temp and low-temp detergents available

• Cleans all forms of fuel injectors, including GDI
• Enhances fuel stability; reduces gum and varnish formation
• Use one bottle per tank for most effective treatment, cleans to nearly 100% efficiency in one treatment
• Reduces need for octane by up to two points
• Contains synthetic upper cylinder lubricant
• Cleans pollution control valves
• Suitable for use with oxygenated fuel
• Safe for continual use

So I wonder what they mean, I wonder if you actually have a lower octane for use, or it is just bs speak, dunno. What you can do is next time try a lower octane fuel and only do 1/2 a tank with one bottle, same mix rate as you have now. Then it will either be worse, better, or the same. Then you can adjust even with octane boost if needed as in it got worse. But I never heard anyone using 94 octane in a stock 5.7. Lots to digest here, but also this is a known issue with heavy dose. Seams like about 1/2 the bottle is oil, so adding two bottles is like adding about 16 ounces oil to gas. Now, could this be the source of hesitation? possibly?

[Burla]

Or someone could try running 16 ounces Lucas UCL and see if that hesitates. Gets real simple if that causes a hesitation.

Interesting, indeed!

Here's my $0.02 (and some real-world, too) on lower octane, especially in the summer high heat times of year.

Using regular 87 and smashing the go-stick and holding it to the floor through the first few gears until I'm at 120km/h to 140km/h, especially in the summer months when the heat is high (A/C on only amplifies it more)...there is a very apparent spark-knock / engine-knock sound.

(89 is a complete farce and not worth using IMPO!).

Migrating to 91 and doing the same, it's intermittent. When it does knock, it's mild.

Using 94 and 93...ZERO knock whatsoever (A/C on or not, and going up a steep hill and smashing it, too).
And, my HEMI is zippier as well.

I only use the 94/93 when I use the two bottles of SI-1, and again, it's only a max of a couple of times a year.
All other times I only use 91. Although the 91 Shell runs the best whereas 91 Costco not as good. All top-tier branded fuels though.

You all know the oil & filter I use, so it's only quality product.
I remove the TB and thoroughly service it twice a year as well as remove the PCV valve and do the same, too.

My engine air filter is changed out every 6-months (using the OEM 6.4/ECO air filter with the bigger lower air box and intake horn mod) and a Legmaker mid-tube upgrade with the IAT located in the center of the air intake horn in front of the airbox assembly).

My spark plugs are changed every 60,000Km's or so as well.

My HEMI is well maintained, but well driven!
