Increased gas economy

[This review was collected as part of a promotion.] The packaging was solid and durable. You get what you pay for in this, as you will see the difference in how your vehicle burns fuel. I didnt pay attention to the smell but it couldn't have been too horrible if I did t pay attention to it. I have a nose like a rabbit.

Easy to use.

[This review was collected as part of a promotion.] Very easy to use, just remove plastic packaging, remove cap and safety seal, and insert into your vehicle's tank. The bottle has a long slim neck, so it's very easy to add to your gas tank. I honestly didn't notice any sort of scent. This is like giving my truck and energy drink.

A quick, affordable boost that noticeably improves

[This review was collected as part of a promotion.] I used the STP Octane Booster in my older sedan that was starting to show signs of sluggish acceleration. After adding one bottle to a full tank, I noticed a noticeable improvement in performance, especially during highway merging and uphill climbs. The car ran more smoothly, and I experienced a slight increase in fuel efficiency over the next couple of refuels. The packaging is compact and easy to pour without spilling, and there's no overwhelming chemical scent. For the price, it offers great value and a quick way to boost engine performance between tune-ups.
