So I hit the 200K mark in my Focus about a month ago, and now im approaching 203K.


I was looking at the following two fuel system cleaners:
STP Complete Fuel System Treatment http://www.stp.com/fuel_cfsc.php

OR

REDLINE http://www.redlineoil.com/product.aspx?pid=80&pcid=12

Which of the two would be suitable for these cars?
Which one have you used? Or do you use any additives/treatments?


A little background info:
2002 ZX5 = 2.0L Zetec.

I did a tune up at 188K (new plugs, wires, Air filter, fuel filter and PCV valve), which was back in April.

Transmission Filter done last week.

Oil changes are done every 3500-4000K , with regular 5W20 oil (Motorcraft or Esso) and quality oil filters (Motorcraft or WIX).

All service/maintenance is done by myself!!

Fuel used: 87 from any major gas station, ESSO, Petro, Sunoco and Shell.

80% highway speed, 20% stop and go, to and from work. (Scarborough to Aurora and back)


Awesome car in the time Ive had it (since April/09 @ the 188K).


Would like to keep this car running/looking tip top for many more years!

Thanks!!
