So in my quest to aid my fuel dilution (and not so fantastic MPG on the Yaris), I've added a maintenance dose of RedLine SI-1. I'm a little concerned with dumping the whole bottle in there (as I only have a 40L tank (about 10 gallons), after all). What do you folks suggest? Continue with single ounce doses? Half a bottle and one-ounce doses there-after? Or just dump the whole thing in?
Red-Line SI-1: Whole bottle or maintenance dose?

I have added a full bottle when I only have 5 gallons of gas left. Doing it for years.
I say do 2/3 of the bottle and save the other 1/3 for maintenance dozes.

On a ten gallon tank, I would do a 1/2 bottle, then another 1/2 bottle on the next fill up. After that, I would add 3 oz per fill up. Now, that's what I do with my cars but they hold more than ten gallons. Here is what Dave at Red Line says about it. Taken from an email to me:
Johnny,
Thank you for contacting Red Line Oil, the maintenance dose is about 1.5 ounces per 10 gallons of fuel. Ideally it should be used on a continuous basis, for continued lubricity, to maintain the injector cleanliness as well as working to clean intake valve in combustion chambers.

I'm with Johnny here, that's what I'd do in your case. Me personally, I run good Top Tier gas (like Chevron, Shell, etc) and just dump a whole bottle of SI at oil change time. The top tier gas will do a decent job of keeping you clean. I don't think a maint. dose is really needed at every fill up unless you don't have access to good gas with Techron or equivelent.
I fill up with Shell exclusively (fleet card from my biz).
I have a UOA for the Yaris on here, and someone suggested the RedLine SI-1 to possibly help with the fuel dilution (~2%), based on the fuel gauge (and me ending up dumping the whole bottle in), I don't think it did anything but waste my money.

I find too much SI-1 on 1NZ-FE give worse mileage and less power.
The maintenance dose I find the best is around 0.75-1 oz per 100 gallon. If you never use this, you can try half bottle for one full tank. FYI, I use 5w-30/0w-30 engine oil.
If you use thinner oil xw-20, the recommended dosage 1.5oz/10 gallon might be better.
Just make sure the fuel dilution is not caused by sticky ring, since this engine is prone to that. Use auto-rx or engine flush to clean it if needed.

I'm going to run out this entire six month OCI, and get another UOA. May have to order Auto-RX, not sure how much it runs to get it up here, however.
Alright, just checked, ARX is EXPENSIVE to get shipped up. I am still interested, but I'd likely order a dozen bottles and split with friends.
Forgot to mention, all the oil stash is 5w-30, for simplicity, and as stated elsewhere, I dumped the whole bottle in.

I was a faithful user of this additive for years until I added a half bottle of Redline SL-1 to the gas of my 97 Chevy pickup with a 5.7 V-8 engine. Within two days, the engine began to hesitate and then fire on 6 or 7 cylinders. Finally, it barely ran. I managed to limp it in to the dealer. Upshot was that the injectors were filled with a fine sand-like substance that dissolved in MEK or acetone but not in gasoline. Two of the injectors had to be replaced. Mechanic, whom I had known for 25 years, immediately asked if I had added a gasoline additive.
Since then, I have only used the Lucas gas additive.

Was the substance in the additive or your gasoline tank?
i don't think SI-1 has MEK or acetone. i've shock dosed the whole bottle in 10 gallons but the 1/2 bottle now is a good idea
speculating maybe the sand-like stuff was from tank sediment freed up by the SI-1? also isn't your fuel filter supposed to stop particles that big

Wow, you have a 100 gal tank?
Hahaha..my finger like to type more zero on numbers
it should be 0.75-1 oz per 10 gallon.

Anytime you use a shcok dosage, change the fuel filter.
