I have been an avid user of ZX1 since I first tried it, I have used in all cars in gearboxes differentials and engines and it has never failed to show an improvement. However I now have a Toyota Prius I have covered over 100,000 miles in it so warranty has now expired, I have added ZX1 to the engine but not the trans-axle, firstly because when I asked at Toyota they said it would probably distroy the box and definitely invalidate the warranty and secondly because I wasn't sure how it worked or whether there were any particular weakness with it.
I did approach ZX1 technical help who said they could see no reason their product wouldn't benefit this application but I now love the car I thought I would hate (bought to save me money and help me slow down)<<didn't slow me down much but saved me bundles
.
Does anyone know of anyone who has used this product in a Prius? If not anyone see any reason I might regret taking a chance. Your input would be appreciated
