How much STA-BIL should I add per gallon?

Technical Discussions

I’ve been looking into using STA-BIL fuel stabilizer for my car, especially since I’m planning on storing gasoline for a while. I want to ensure that the fuel stays fresh and doesn’t degrade. I came across different recommendations online about how much to mix in.

Questions:

  • What’s the standard dosage per gallon? I’ve seen figures like 1 ounce for every gallon but want to confirm this.
  • Does the dosage change if I’m storing more than a gallon? For instance, for a 5-gallon can, would I just multiply that?
  • Are there any other tips I should know when using STA-BIL? Anything specific to automobile storage rather than just general fuel storage?

Any insights or experiences with using STA-BIL that you could share would be greatly appreciated! I’m eager to keep my vehicle running smoothly for as long as possible, especially in the off-season.

Generally, I recommend using about 1 ounce of STA-BIL per gallon of fuel for optimal performance. This applies to both gasoline and diesel blends. Always check the label for specifics, though.

That sounds right! Just make sure to give it a good shake after adding it to the fuel tank.

When using STA-BIL for ethanol blends, it’s crucial to use the correct amount to prevent phase separation. Sticking with the 1 ounce per gallon rule is a solid start!

Does this change if I’m using premium fuel? It seems to vary from brand to brand.

For premium fuels, I’d say stick to 1 ounce as well. It’s designed to cater to all fuel types, ensuring protection and performance. Don’t overdo it!

I prefer using a little extra, maybe 1.5 ounces just to be safe, especially for seasonal storage. Better to be cautious, right?

While I get your point, too much can lead to gumming, which is counterproductive. Just stick to the recommended amount.

Can STA-BIL be mixed with other additives? I have a few on hand already and don’t want to mess anything up!

It’s usually safe, but always check the labels. Mixing different brands might cause unwanted reactions. Just stick to what you know works!

11

Thanks for the reminder! I tend to forget to double-check them.

I’ve read that STA-BIL can last up to 2 years in fuel when stored correctly. That’s impressive for a preservation product!

13

2 years sounds too good to be true! Is that for all types of fuel? What about diesel specifically?

14

Yes, diesel can last even longer with STA-BIL! Just remember that it’s best to check periodically…

15

With how I use my equipment, I’ll be checking more often! Does anyone store STA-BIL long-term? Any issues?

16

I stored some STA-BIL for about a year and it worked fine. Just keep it in a cool, dry place and it should be good. Plus, maybe try not to open it too often.

17

I’ve always found that using 1 ounce of STA-BIL per gallon of fuel is the sweet spot. Too much, and you might actually end up with engine issues due to fuel thickening! Just my two cents.

18

That’s good advice! But what happens if you add too little STA-BIL? I’ve heard it can lead to gummed-up carburetors.

19

Absolutely, wueric! If there’s not enough, the fuel can lead to oxidation and phase separation, which is a nightmare for any engine. Just make sure you’re measuring accurately!

Is it really that critical though? I mean, are the consequences severe? What’s the worst that could happen?
