I did an in depth morning cold start video. Documenting MPG, Water temp, valve tick, and piston slap. Now I am editing it.

You will be able to make your own decisions from these videos. final take, it took 3 days for any increase in MPG. Piston slap is gone. , morning lifter noise is much shorter, no change in water temp but very notable throttle response. I’d give Prolube 2 thumbs up. Too bad they only accept 8 second videos. Maybe Prolube would like the full versions

I’ve used Lucas for years and have never quite got the results from it like I have with the pro lube product. Almost instantly noticed my little tick quieted down. Everything feels smooth.

Good stuff, a lil pricey but if the longevity is better than I expect it will be well worth it.

Thank you
