Howe's Diesel Treat
I've been using this for a couple of years now. After recently reading about Stanadyne I'm wondering if I'm maybe taking too much on faith with Howe's. It gets good reviews but how much do any of us know on that stuff.
I've been using HPR fuel almost from the start with my SDL (not dead yet). Word is that HPR needs a lubricity enhancer. Howe's is definitely more afforadable than Stanadyne - about 3 cents a gallon as opposed to 14 cents with Stanadyne. Does one indeed get what one pays for in many cases? I have a routine - I bought a 5 oz bottle of the Lucas gas treatment, put that in my Beemer, cleaned the bottle and fill it with Howe's using a funnel. I stash that in my trunk and empty it into the tank on major fill ups. Supposed to be one ounce per 5 gallons. Here's a pic of the bottle, might jog the memory: https://d2ul0w83gls0j4.cloudfront.ne...600/509106.jpg |
Since the anti-gel is on the label that is obvious but what is it you are targeting? Better lubrication for the Injection Pump and or raising the cetane rating.
This is a test from many years back so it may no longer apply. It is a test for lubricity. Lubricity Additive Study Results - Diesel Place : Chevrolet and GMC Diesel Truck Forums Also companies also often make more then one product. So a companies one product did well it does not mean the others will. In short beyond the Companies claims there really is no way for common folk to test. What is interesting how well having a percentage of biodiesel did. |

If is said it raised the cetane I did not see that. |
Project Farm on YouTube just posted a video comparing a bunch of diesel anti gel additives. He does a lubricity test.

I watched part of that vid, I'll watch all of it.
When I started using HPR I could have sworn I read that it was poor in lubricity. Now I find this: Quote:
One would think they would have an interest in something like that. |
Additives tend to be expensive. I wonder if just adding a few ounces of new vegetable oil per tank would increase the lubrication factor of the newer fuels enough. Or even just a few ounces of new motor oil.
Although this has to apply to older diesels without sophisticated emission controls. |

When I started using HPR, I found a forum post where someone actually wrote a letter to Propel and he actually got a response - IIRC they said that HPR has higher lubricity than normal diesel, and included a MSDS or something similar. I was searching for the post recently and could never find it. I like HPR, gives me better power but I don't use it much because I get worse gas mileage. |

Do you remember the dosage per tank or gallon? You used. I have and frequently run across unused surplus transmission fluid. It would be a cheap additive for increasing the fuel lubrication. It has some detergent additives as well I believe. So it might help keep the fuel system cleaner. You just cannot use it on the newer diesels with particle filters. Yet great for the 616 and 617s. |
I read one description on installing a new spin on fuel filter - they suggested filling it with diesel of ATF fluid to eliminate cranking to fill the void. There's a better expression for that but I can't place it right off.

I bought my first diesel in 1979. (brand new '79 Rabbit diesel). 5 more since then.
I have never bought any additive other than using ATF to fill fuel filters when changing them out. That '79? Kalifornia dmv charged a $500 fee because, "We are unable to smog test this vehicle." Seriously, , , , this is what they told me. |
I've settled on 1oz 2-stroke/gal based on the lubricity study and problems with a Cummins 24V injection pump. My recollection is that Howse wasn't great for lubricity. Some Stanadyne version was near the top but is easy to over dose because it is relatively concentrated compared to other options. 2-stroke is readily available and cheap at Walmart sold in gallons. ATF is discounted in the Cummins forums especially used and unfiltered.
I don't believe that the mechanical injection pumps on a 617 nearly as sensitive as electronic newer IPs. |
