The box was delivered and had the smell of gasoline. I opened the box only to find two of the bottles cracked and leaking. Very disappointing. Even more disappointing is that I am unable to process a replacement. I will be finding another source to purchase from in the future.

The bottles that I received treated up to 21 gallons, not the 28 gallons pictured.

One busted in the package when it was delivered. Customer service sent a replacement immediately.However, the manufacturer has reduced the thickness of the plastic and it is brittle and fragile..

Love this stuff! Give you better mpg and the reason for the purchase also better acceleration. Great stuff! Hard to find though. This shipment never got to me. Someone from Amazon stole it for sure >:-(

I purchase this item because I drive 3 luxury cars all requiring the use of premium octane gas... only problem is, premium gas costs $1.00 (+/-) more per gallon three cars @ 22 gallon each = 66 gallons cost of STP booster costs me $14.00 saving me $52 per fill up for all three cars per tank.Regular gas is 87 octane and premium gas is 91 difference of only 4 octane points, certainly not worth the extra dollar per gallon and STP octane booster gives you 6more points to your tank per bottle, which is a better deal money wise and performance wise.I have to say this product works.

I believe this is a great product and have used before.Unfortunately dissatisfied with the delivery considering it was local 2 days ago and looks like it then got damaged.I'm unsure what happened in the local process. I believe this is an Amazon issue that should be adjusted.
