I bought a bottle of Engine Restore for my Acura V6 because I was losing compression in cylinder 4, so I decided to put it up for the test!! I did the first compression test at 6 miles after emptying the whole bottle in. It ended up misfiring again from cylinder 4 a few miles later, however i did see an increase from 120psi to 165psi after driving it 108 miles..thats an increase of 45psi !!LMK YOUR OPINION & WHAT YOU THINK OF THIS PRODUCT. WOULD YOU USE THIS ??
