“I do not use any type of fuel additive. My truck camping truck is also my daily driver and never sits for more than one week, so there is no need for an anti-algae additive.
Having been a service writer at a Dodge dealer, as well as having Cummins engine training, I was advised against the use of any type of additive, especially on a 24 valve Cummins. My son-in-law has a late 1990s 12 valve Cummins. He also has never used additives.” – Bob Watts, 2011 Dodge Ram 2500, 6.7 Liter Diesel, 2000 Fleetwood Angler 8
“Yes, I use a fuel additive. Over the years I have tried almost every brand but settled on one that has actually improved my miles per gallon. On average I get 1.5 to 2.0 miles per gallon better both unloaded and hauling/towing.
I use Power Service Diesel Kleen +Cetane Boost Injector Cleaner and Performance Improver (grey can). I add proportional amounts with every fill up.” – Tom Adams, 2001, GMC, Sierra 2500HD, 6.6 Liter Diesel, 1998 Northland 10-foot
“I burn regular diesel and 20% biodiesel depending on who has the lower price. I occasionally add Lucas fuel stabilizer to the regular diesel. I have 190,000 and it’s running great.” – Ron Williams, 1997 Ford F250 SD, 7.3 Liter Powerstroke Diesel, 2003 Lance 1010
“I use Power Service in a grey bottle (for warm weather).” – John Godfrey, 2012 Ford F350, 6.7 Liter Diesel, no slide-in at present (but a 32 ft fifth wheel)
“No. I have used a fuel additive in the past to increase the cetane but the current truck has ample power and needs no increase in power for our use. The algae you mentioned in the article has me thinking about using an additive for that purpose, especially when the truck is not driven for a while.” – William Chiles, 2015 Ram 3500, 6.7 Liter Diesel, 2013 Lance 1050S
“We do not use any fuel additives in the truck. One of the reasons we purchased a gas engine was to eliminate higher costs of diesel maintenance or fuel additives and diesel fuel related issues.” – Paul Stewart, 2006 Chevy 3500, 8.1 Liter Gas, 2000 Summerwind
“I use a cetane booster that I purchase from the local Ford dealer. After a lot of urging, I now buy my fuel from name companies like Chevron, 76, Texaco or whatever.” – Steve Timmings, 2003 Ford F350, 6 Liter Power Stroke Diesel, Four Wheel Camper Hawk SC
“I use Power Service in a grey bottle with every refueling. I use the regular amount listed on container. I also use Biobor from West Marine, Power Service from Walmart, or Tractor Supply in late fall. My vehicle is not a daily driver. I use it only for projects or recreation.” – William Mega, 2001 Ford F350, 7.3 Liter Diesel, 2000 Lance 835
“The problem with our domestic diesel now seems to be lack of lubrication for the pump and injectors. With my 2002 Powerstroke I used Walmart two-cycle oil at a mix of 100 /1. I sold that truck at 100,000 miles with no fuel system problems at all. With my 2015 Duramax I try to maintain a minimum of 2% biodiesel. I blend either B10 or B20 depending on availability and the season (things tend to get cold here in western Wyoming).
I try to buy 5 to 10 gallons of B100 when it is available to use as an additive when on the road since biodiesel is hard to get in some areas. I keep the B100 in my cool basement and have had zero issues with algae or deterioration.
I do not ever intend to run biodiesel as rich as B20 even though my truck is officially sanctioned for it. Scarring tests show that the greatest lubrication improvements can be achieved with as little as 2% biodiesel.
I don’t drive the truck a lot in the winter, but so far Howes has seemed to prevent gelling for me. Pump failure seems to be a rare but expensive proposition as it takes out the injectors and complete fuel systems, usually after the warranty is up. I guess we all pay our money and take our chances.” – Robert Benesh, 2015 GMC 3500, Duramax Diesel, 2004 Alpenlite 850
“We have added Opti-Lube to all of the diesel trucks we have owned since 2009; a 2009 Dodge 2500, a 2012 Silverado 3500 HD dually, and now a 2015 GMC 3500HD dually.
We add it every fill up, and use it year round since the truck is my winter commuter vehicle as well as our summer truck camping workhorse. We also tow a 20-foot enclosed trailer with mountain bikes, gear, water, fuel, and a RZR (or motorcycles or racing Miata). The diesel truck is needed and loved.
The Opti-Lube was highly reviewed and recommended and has served us well. You can even get it in small travel bottles. On the road it is easy to add with each fill up.” – Tracy Schuster, 2015 GMC 3500, Duramax Diesel, 2012 Lance 992
“I started using Archoil shortly after I purchased the truck in September, 2015 with 224,000 miles. I did not have the truck long enough to solidly say using it made a difference.
I purchased the truck with a 2003 Bigfoot camper on it. It was an affordable package but I knew I had better take extreme care of the high mileage truck to avoid any regrets. I did end up having the transmission rebuilt five months after I purchased it. It was not unexpected and I actually have more peace of mind knowing I can take long trips hauling the camper and trailer with a new and properly maintained tranny. I will keep using Archoil in the fuel and oil until something better comes along.” – Bill Ortiz, 1999 Ford F350, Power Stroke 7.3 Liter Diesel, 2003 Bigfoot 25c 9.6
“No. If you use good gas from the get go you won’t need any additives.” – Timothy Chapell, 2013 Ford F150, 3.5 Liter Ecoboost Gas, 2013 Palomino SS-1251
