I had a previous thread on this stuff, I cannot find it so heres a brief synopsis:
A friend bought an 08 Tacoma with a 1GR engine from a private party. It had 300k miles on it and a nasty ticking on the right cylinder head. Looking through the prior owners maintenance records it had been going on for at least 75,000 miles. A dealer told him he needed a long block.
I told him to just run it and when it failed we’d find him a good used one. It ran great, just sounded terrible. He bought a can of Bestline and I was skeptical (to the point where I lovingly berated him with mockery). He did an oil change and added a bottle, drove it and a half hour later the engine was silent. The 1GR isn’t known to be a really quiet engine but this thing sounded amazing. I was stunned and humbled. It stiil is purring 6000 miles later.
Fast forward to last week. One of my customers with an early Hyundai Accent comes in for a squealing PS belt…..there’s been a noisy tappet for a long time in that motor.
I had a half full bottle of Bestline on the shelf, my co-worker poured it into the motor while it was running (no oil change, he just poured it in). I let the engine run for 15 minutes (I usually will run a new V belt for a bit then recheck the tension). During this time, the ticking slowly disappeared. We were both in disbelief. I never said anything to my customer, just gave him the car back. He shows up yesterday and asked what we did because the engine sounds so good, so I told him about the additive. He’s thrilled because he loves the car.
My conclusion: If you have a noisy tappet/lifter, try this stuff. What ever detergent this stuff has is amazing. Never in my life have I fixed an engine noise by pouring in an additive…..and this stuff worked twice on noisy tappets. A half a bottle quieted down the Hyundai with dirty oil in it!
