What this Amazon deal is worth
Lucas Oil High Mileage Fuel Treatment is $5 at Amazon, down from the $8 Amazon had on the listing when our tracker picked it up — a 38% cut that keeps $3 in your pocket.
The average discount across the 1123 deals carrying a percentage on Ring In The Deals right now is 46%, so at 38% off this one is shallower than the typical drop in the feed — it beats 27% of everything else live today.
There are 146 Miscellaneous deals live at the moment, and measured in dollars saved this is the 144th biggest of them.
We posted it 3 days ago, and it comes off the site on October 20, 2026, 30 days after posting. Retailers change prices and stock without warning, so Amazon's own page is the final word — confirm the figure at checkout before you buy.

How we check: our tracker reads the retailer's own listing, records the price and the original price exactly as Amazon published them, and posts the deal without anyone retyping a figure. No discount percentage is shown unless both numbers came off that listing. More on how a deal gets on this page.
What we make of it
This fuel treatment is designed to help maintain and improve the performance of older vehicles, making it suitable for cars with high mileage that may struggle with engine efficiency. It works by cleaning fuel injectors and improving combustion, which can lead to better gas mileage. However, some users report that it can cause engine knocking in certain vehicles, so it's wise to check compatibility and user reviews, especially if you drive a model known for sensitive engines.
Why this is a good deal
It is shallower than the typical Miscellaneous discount
The median discount across the 146 Miscellaneous deals we have live is 51%. This one is 38%.
What you actually keep
$3. A percentage is a ratio and a saving is money — on a cheap item a huge percentage can be worth less than a modest cut on something expensive, so this is the number we would judge it on.
Reasons to think twice
we have only seen this product once, so we cannot tell you whether the original price is a genuine going rate or a list price that nobody pays; at this price the shipping threshold will usually matter more than the discount; the discount is only a saving if you were going to buy the thing anyway.
