Apparently thousands were satisfied and no one asked for their money back.quote:Originally posted by Captain Kirk:quote:Originally posted by Tim Vipond:
Why not use a product formulated specifically for your purpose such as https://www.amsoil.com/storefront/api.aspx?zo=1181889 ?
The PI additive is an expensive cleaner at best. Why not just purchase techron plus when it's on sale half price.
"P.i. Performance Improver Concentrate (API)
Improves fuel mileage an average of 2.3% and up to 5.7%. " At a retail cost of $10.60 for a 20 gallon tank treatment and repeat the recommended 4,000 miles. 4,000 miles at 20mpg and $3 a gallon = $600 spent in gasoline. If you get the average of 2.3%, you save $13.80 in gasoline.
In addition to the $3.20 you get to keep in your pocket, you "Reduces emissions such as hydrocarbons (HC) up to 15%, carbon monoxide (CO) up to 26% and nitrous oxides (NOx) up to 17%. Restores power and performance. Reduces the need for costly higher octane fuel. Reduces noise from carbon rap and pre-ignition. Offers better vehicle drivability and smoother operation." P.I. cleaned off 36 to 98% intake valve deposits, and cleaned off 35-63% combustion chamber deposits.
Here is an 8 page study on the product: https://www.amsoil.com/lit/g2543.pdf .
Can you show that Techron or 2 stroke oil does all of this as well as AMSOIL Performance Improver gasoline additive?
