Thank you for a great product. As first I was skeptical of buying a product that in just one bottle can drop the emissions. I own a ‘86 Suzuki Samurai and it failed the emissions. I bought this car just to tow behind my motor home and did not want to put a lot of money into it. Upon failing the emissions the local garage told me for about $200.00 dollars they would be able to get my truck back on the road. This I thought would be my last option. I checked the spark plugs and all other tune up items and all seemed OK. At the store I found your item and figured for $5.99 I will give this a try. One tank of gas later, here are my results:

ITEM	BEFORE	AFTER
