Best Over the Counter Fuel Additive?

[TXTech11]

Ok, so I'm new here. I'm going to try out Opti-Lube Summer blend, but until that comes in, what would the best over the counter (autozone or something) fuel additive be?

Thanks guys!


btw, I searched and I couldn't find anything on otc additives.

I use the same stuff I used in my 06 6.0, RBP(Rolling Big Power) High Performance Additive. It helps keep everything lubed up, and increases the cetane level and dries out all the water. Its also supposed to reduce smoke & soot by 15% and increase fuel mileage 5%-7%, but to tell you the truth with that Damn DPF it doesn't have any effect.

It depends on what you're trying to accomplish with the additive. The 08 and up trucks are designed to run strictly on ULSD fuel so there's really no need for additives. If you're looking to increase your cetane rating I've always used Power Service Diesel's gray bottle. If you're looking for anti-gel I use the white. As for a write up on additives check this out, it's post #9 TANK'S Library

Also, I'm assuming I don't need any Anti-Gel for the winters here. The coldest it's been while I've been here is around 24*, and it doesn't stay there too long.

thoughts?

No you won't need anything for that. You won't even need to plug it in. When I was in Illinois it got down to -25*F in the mornings and my truck never hesitated too start without being plugged in.

I use the Ford additive..$9.00 at the dealer. 4oz per 28 gallons. treats approx. 125 gallons per bottle. Truck fires right up and i even noticed a increase of MPG's.....i'm a believer.

I just threw some diesel clean in there, I'm not sure if I'm going to use an additive EVERY tank... I mean these engines are designed for Ultra Low Sulfur Diesel...

Since I bought it used, I want to make sure all the injectors are cleaned decently. (I guess)

I use the Ford additive as well mainly for the added lube but noticed the mileage gain as well. I am thinking about trying the XDP additive anyone used it?

I used the XDP additive while waiting for my RBP to arrive, didn't notice anything special about it, the packaging is made to mimic the RBP packaging, so I didn't really like that. But with RBP its definitely noticeable.

My salesman told me not to use anything. His exact words words were "and no matter what anyone tells you don't use any additives, and that includes the Ford additives". I'm not sure why, he wouldn't get in to it but strongly recommended me to listen to him on this???

Anybody out there had problems because of running additives?
