STP produkter, hva mener dere?

[clone baby]

Er disse produktene bare tull eller har de en merkbar effekt?

 

Kjøpte denne- STP® fuel Injector Cleaner

 

 

Men merket ikke noe forskjeld.

 

• Restore lost power and acceleration
  

• Smooth rough idle and eliminate tough starts
  

• Improve engine performance
  

 

Og dette, STP® Engine Stop Leak. Noen som har prøvd denne, eller er det en risk og tilsette dette i motoren?

 

 

• Stop minor oil leaks
  

• Rejuvenate seals and gaskets
  

• Fortify oil with viscosity enhancer
  

 

Over time, normal engine operation can lead to oil leaks. These occur because heat can cause oil seals and gaskets to shrink, dry out and crack

 

Try the complete line of STP® Oil Additive Products: Regular and 4-Cylinder Oil Trea'tment and Smoke Trea'tment.

 

DIRECTIONS: Add entire bottle to oil. Run engine for 15 minutes. Drain at normal oil change interval. If leaks persist beyond 1,000 miles, mechanical repairs may be required. Consult a trained mechanic.

 

 

Og vurderte og kjøpe denne, STP® Complete Fule System Cleaner, men om det er lurt vet jeg ikke..

 

 

 

• Restore lost power and acceleration
  

• Reduce hard starts and engine hesitation
  

• Stop knoc'k and ping (ventil tikking?????)
  

 

Ser jo ut som supre produkter men om det virkelig funker?
