I have a 59 Chevrolet Apache pickup truck with a straight six with hydraulic lifters. Before Prolube it always had a slight tick at start up and after Prolube it’s pretty quiet. The truck just seems to run smother and it was a smooth running truck before but now it’s even better.

Thanks,

Pete

So far I have used this in my daily beater Chevy Metro. It has 277k miles on it and I noticed a BIG difference in the way it idled as soon as I put it in. The gas mileage improved as well.

I also put some in my daughter’s Sonata and she noticed her gas mileage improve that day. I will be using it in my other vehicles now as well. I have been very impressed so far!!!
