Diesel additives

[eruddick]

Hi all, I have a 6.0L Diesel and have been using Amsoil Diesel Injector cleaner and Amsoil Cetane Booster with every fill up. I've been looking to switch to something else and was wondering what others have been using for fuel additives.

Thanks,
Ed

I use Archoil for both the oil and fuel. 16oz with oil change and the fuel additive has it own built in measuring dispenser for fuel ups. Love the stuff and a few other on here like it as well...

I've used Opti-Lube XPD in my 6.0L SMB, my wife's TDI Passat, my '02 F250, and my current '01 7.3L Excursion. No complaints, but I view additives like vitamins. Do they help, maybe, probably? Do they hurt, not likely except for your pocketbook.

Archoil is good stuff and so is Lubrication Specialists stuff. I used the Amsoil stuff for a bit but it messed with my Espar system and made it smoke. Same thing for the engine... saw smoke at times. Switched so not a problem anymore.

A bit like Herb in terms of help or not....

about two years ago I used Archoil in oil and fuel for about 10,000 miles. Not sure it did anything. Maybe a bit quieter.

Last oil change was in January and I have about 6k mi on it- 5W-40 Rotella syn blend and had Hot Shot Secret added to oil and also used the Hot Shot Secret fuel additive. This was over our 10 week ski trip.

Also did a few other things to the engine around the oil change time - had the fuel filter changed, cleaned out the Exhaust Back Pressure tube, tightened up the intake manifold/ turbo hose clamps... oh, and switched to the Hydra Chip w a 60 Highway as the main tune

Who knows what did it but the 7.3 is running really well. MPG have popped up into the 16 to 17 mpg from 13/14. I even had an 18 mpg over a pretty flat 85 mi run between fill ups. That was pretty lightly loaded and 60 - 62 mph with the roof rack removed. Hand calculated with odo error adjusted for.

Now, as to what to use in a 6.0 ????

It's probably not what the cool guys use but I've always run Stanadyne Performance Formula in every tank. I've never had a fuel issue since I bought the van in 2010.

Ray, what size tires you running and what gearing? That’s great mpgs from the 7.3 in the unaerodynamic van. Might have to follow your lead with what your using.

I’ll bet if we all send this guy a message on his channel we can get him to do a test on all the brands people swear by.

It's what this cool guy uses. I still have a 1995 Chevy 6.5L crew cab dually that I bought new in 95. As the Feds slowly took all the sulfur out of diesel fuel I really had no choice but to use something. If i remember right when they went from 1500ppm to 500ppm I was screwed, it was like running a muscle car on 87 octane unleaded. I think that was around 2006ish. So I've been using Stanadyne since then. Got 185,000 miles on it now.

Yes Shea, even on the ski trip I was pretty impressed and we were well loaded up, skis on the roof and dealing with mountains. This trip to SoCal and back was first trip with light load. Tires are KO2 285/70-17 w 3.73 gearing l, air pressure at 60 front/ 65 rear.

From some research I did the EBP tube can have quite a negative effect. I used some old bike brake cable and carb cleaner to clear if out. It is located at the front of the engine block. I was also a bit surprised at how loose the hose clamps were on the short hoses connecting the turbo Y to the heads(???). I just snugged them up.

The oil additive /stiction eliminator May have helped.

And then the Hydra Chip is really well behaved.

Too many variables but the EBP and hose tightening are near no cost to try out. Just do not break something in the process

The other thing I think worth checking is draggy brake calipers/pads.

Thanks all for the recommendations.
