The only way a sixbanger can see those king of gains is if they're running Royal Purple 5/20 in their engine.
I heard the Royal Purple mod is only worth 5rwhp in our 2V cars
, but if you have a Termi it's worth almost 15!
Forreal? Dang.. I thought I gained about 20 when I added Royal Purple gear oil, transmission fluid, and engine oil.. What about mileage boosters? Those 5 dollar ones at Walmart, I heard they can almost double your gas mileage per tank???
