Prolube I’m a believer in your product it quite down my engine so far it work great

I seen the adds for about a year and finally bit lol. It definitely works as far as making my engine quieter. I just wish it was a little cheaper or came with a funnel but that’s just me being me lol it’s a great product can’t wait to try on my other automobiles

Plain and simple, it works. Use it on my 1986 Trans Am

And its runs just a little cooler, quieter, especially at start up and a little smoother thru the high rpm range.

I like the smooth running engine sounds now

I have a 2006 scion xb. Always ran great but motoro sounded like a sewing machine and a little louder than I like. Used the recommended amount and it quieted it down considerably lower. I will use this in all my vehicles now. You have gained a lifelong customer.
