![]() ![]() Howe's provides some anti-gel protection but it does nothing for my mileage. And it provides some lubricity if I happen to pick up a tank of non-biodiesel somewhere. I know, I drive a Dmax but I figure if Cummins buys off on it, that can't be bad. Can't hurt that Cummins approves it as well. But over a few tanks it seemed like I usually gained close to 1mpg on PS so I started running it year round. It's a tough trial depending on conditions, i.e. What I found in my trials was that pretty much anything with cetane boost improved my mileage. Where I buy most of my fuel, the pumps are labeled B5-B20 biodiesel so I quit worrying about lubricity. Running an LML, I've been concerned with fuel lubricity until I saw the lubricity test that showed biodiesel provides much more lubricity than any additive. Haven't tried HS Secret but I'm sure it's a good product as well. I've used PS white jug and gray, Stanadyne and Howe's. In the end it's your truck and you need to ake the final decision, but I'd not think twice about it. That tells me all of thes additives are pretty compatible. as in a full dose of each in one tank full. Standyne lubricity formula and Standyne performance formula can be used TOGETHER. If you see separation then I'd maybe be concerned. If your really concerned mix a small clear jar of the two and shake the crap out of it. They pretty much have to be don't they? If they are soluble in diesel then they have to be solubale in each other. Most all of the additives are compatible with each other. Desired PSI ve actual, injector balance rates are all WELL within spec.Īs far as mixing brands of additive. I'm only at 190k on my LLY but the fuel system seems to be plenty happy. ![]() After all if some is good, and more is better, well then a whole bunch too much has to be just about right doesn't it. I can guarantee I over estimate how much additive is needed. So we guestimate, 'ohhh about this much' and dump some part of a bottle in the fill neck and fill up. We pull in to fill up and have 1/8 or 1/4 so showing on the gauge. When I say 'overdose' I bet most of us do it. In fact one injector that used to run a balance rate near -4.0 has 'healed its self' and now is consistant -3.2ish. No one had any feedback but, in all honesty I have dosed my LLY at the MAX and probably then some in the 2 years I've owned it, No ill effects. Has anyone else tried this Hot Shot's injector cleaner on their Touareg TDI? Did you get noticeable improvement in performance?I posed the question here some time ago about the effects of 'over-dosing' with a fuel additive like Standyne. They are the company that remanufactures most injectors Been using it in all my Diesel engines for years. I'll keep using this additive and report back with my longer-term results. But maybe I do indeed have clogged injectors, and maybe this stuff actually does indeed clean injectors. Maybe it's just randomness of air pressure and ambient temperature over the last five days. I'm driving the same roads and fueling at the same station, so those are constants. My regular city mileage has been 20.5 mpg for months now, so I was hoping to see it go up to 22 mph.ģ00 km later, my tank is at 1/2 full, and something is going on with my engine. I'm pleased with the other Hot Shot's products, so I decided to try this Extreme Concentrated Fuel Injector Cleaner.įive days ago, I put 6 ounces of this stuff into my fuel at the 3/4 full mark. In addition to "walnut blasting", this product kept coming up in my web searches: My 2015 TDI Execline is at 125,000 km, so I've been researching options for addressing carbon buildup. ![]()
