darrin,Actually,I drive my car 265 k's /day,just to and from work,never mind evenings and weekends.
I tried the "gold" because I heard it was good,but I didn't notice any difference between it and the other stuff I use,primarily because of convenience.I have Shell and Pioneer stations close to my house,and a Shell close to my office.I don't know what grade Pioneer is,but I use Either of the Shell grades,depending on which pump is open.I'm not saying Esso,Husky,Texaco,or any of the others aren't as good,I can't remember trying them.Actually,wait.The best tank of fuel ,for distance,was from Esso on the New York State Turnpike in Angola.
I try to find a BRAND NAME station,that has busy Diesel pumps, I feel more comfortable doing this.I'm on my 5th VW diesel,second TDI,and no problems so far....touch wood.
Sorry,I didn't find the "gold" to offer any noticeable difference.
