Coming Soon


I was using Arco gasoline in my Buick LaSabre (2000), as a savings option. My engine began to foul and the check engine light eventually came on I returned to the dealer and was informed that there is some particular additive in the Arco gasoline which is not compatible with the GMC injectors… the problem was addressed. Performance had not returned however, so needless to say I had been disappointed. When you sent the injector cleaner I felt anything would be worth a try. I followed the directions and I must say that I am most impressed with the product. The engine performance has returned as though it was new and the mileage has improved dramatically.

Thank you so much.
