Jim,I went crazy with SI. 1 bottle(15 oz) EVERY fill up and have gone through about 20 bottles so far. Never skip a bottle when filling up gas. Also always use Shell 93 V-Power Nitro. The vehicle is at 245,000 miles now and the engine has been an issue with oil consumption since it was brand new. It is safe for CATS and O2 sensors.
You should fill in your truck profile.
What year and engine do you have?
"Oil consumption since new" what is the cause?
