Confused about various diesel additives

[Diamondpilot]

As LT Cheg said the problem with diesel fuel is there is very little quality control. I have got 2-3 mpg lower after a fill up at a station other than my normal station. All my neighbors have diesel trucks also and say the same thing when they are traveling. Its not like gas where you know what you are getting via the octane rating.

I use PS in the white bottle and have for years. No issues at all.

Opti-Lube XPD for me.

Same here. Get a 2 mile difference between Shell and Valero fuel. Shell being the higher.

I use Power Service in the white bottle year round, no problems. I put a little more than called for, as I don't use that much diesel in my BX23.

For 9 years now I've run Stanadyne Blue in the winter and Stanadyne Junior in the summer in my 2001 Duramax LB7, and it seems to work great. However, it might be like elephant repellent spray, which would also work great around my place. However, the "experts" on the Diesel forums seem to think it's the best going, and I'm told GM has approved it for their older Duramax engines. Lots of folks also use the Wally World stuff and like it, though, and no doubt it's cheaper. Since ULSD I've always felt I should use something, and the Stanadyne only adds about 8-9 cents a gal to my fuel costs. Seems worth it to me, but I'm not a heavy driver (2001 Duramax, 70K miles).

Red bottle of power service is for emergencies only. Use the white bottle for winter, and gray for summer.

The collective experience on this site is amazing. Picked up a bottle of white PS for now, a gray for next spring and some 911 just in case. Appreciate the help! - Dana

I have done some reading on the subject, and I think it's a waste of money to add anything except in the winter to prevent gelling. I found the article on this web site on a long series of post about additives. The gist of the story was if additives helped, they either add them at the refinery or would if the helped.

I use a Qt. of PS white bottle per 55 gallons of diesel.
