It really Works.and is a Reasonable Price.
I have used STP injector cleaner for many years in the last 5 cars and have found his product to work were others have failed.
I thought i would give new Ultra 5 in 1 a try and was not disappointed.
MK 7.5 VW Golf 1.5 TSi DSG
Filled petrol tank up added STP 5 IN 1 and did 450 miles did not notice much change straight away but
a few days later we went for another short run of about 60 miles and after 10 minutes that day the car just felt much smoother and with out any doubt more responsive to small throttle inputs and very eager through the rev range
Even though i always use 2 bottles of STP injector cleaner each year on my cars this new 5 IN 1 FORMULA seems the best yet to me and will mow use this new formula twice a year on my cars
as this is STP new bench mark for me and my partners cars.
