Does anyone plan on using or are already using any oil/fuel additives in their Duramax such as Zmax, Hotshot or similar products?
What is the affect, if any, on the Particulate Filter or emissions? I use stayntune (fuel) with my Golf tdi, no oil additives but religious changes at 5000 miles. Samples are excellent and no mechanical issues (knocking on wood) so far at 242000miles. I think I may use the same regimen with the Chevy, but have concern on impact to emissions. Any feedback would be appreciated.BG makes a cleaner I use once a year that cleans tank and removes carbon. I can tell a big difference when I use it.
As of this am, 6 Jul 0755, two filter w/cap units in stock. Considering the cap does not look as robust as euro types, I opted for the full unit.Went for my 1st free oil change today and the dealership doesn't have an oil filter for my truck at all! They have sold 4 diesel Colorado's you would think they would have everything for a proper oil change. Where is everyone else getting their filters from?
You can try resetting your trip B odometer once you start using the additive to see what it does to the average mileage. This can be used to compare the delta with your lifetime average MPGs. That’s what I did anyway.I received an order of the TDR-WDA (winter) and TDR-FL (summer) products from Amalgamated but I honestly cannot vouch for it at this moment as I have not used it yet and really would not how to test the results - but I believe for better or worse Internet reviews on the product and also the vendor's biased propaganda touting a high lubricity rating
I will do a follow-up post in spring of 2019 on the Amalgamated product after I've used up all my Liqui-molly stuff - which honestly I can't say has not hurt me but also cannot say has had a *OMG WoW!* effect on me either, seriously any noticeable changes with any product of this kind is hard for the average user to discern any noticeable improvement
I know this post is not helping anyone really decide what is best (that's where I'm currently at being as lost as most) but interweb research is pointing me in the direction I'm headed now after trying at least 4 additive brands so far.
DISCLAIMER! I'm no expert and new to diesel engines so if anyone ever does what I do and you blowyurengineup, its s'not my fault...
I’ve been using the amalgamated product in all 3 of my diesel vehicles. Use the advertised recommended dosage of 400:1. That is 9.6 mL per gallon of fuel.CleverUserName and EKarlW - Thanks for your posts and info. I am in Socal so I have used the summer formula TDR-FL in my 2018 Z71 2.8L since new and now have almost 18k miles on it. I do such varied driving with it that getting accurate, consistant fuel economy numbers is hard. With all the idling I do for work and stop and go LA traffic, I average about 23 mpg. Cost is $98 for 2 gallons shipped to my door. There are different ratings for cetane improvement and other specs on their website but the Amagamated, Inc website does not state their HFRR lubricity test rating drop on it, I asked them and their reply is below. The best observation I can make is that I have had no issues with this 2.8L Dmax engine plus the DPF regens have been getting further apart. The dealer has added urea a few times so it is doing it's regens. At a cost of about $2.32 for 6 ounces per 20 gallon fill up, it has been pretty reasonable IMHO. They recommend 3.2 ounces per 10 gallons diesel fuel. Can either if you share how many ounces you use per 20 gallon fill plus any additional data or thoughts on this product?
From Almalgamated, Inc. May 20, 2019;
"The answer is that it should drop the lubricity rating approximately 70-100 points. The end point wear scar rating depends on what the base fuels wear scar rating starts at. Most diesel fuels in the U.S. have some lubricity components already blended into them during the refining and finishing process to get the rating down to 520um or below. Utilizing TDR-FL aids in achieving many Engine Manufacturer's preferred 460um or lower wear scar rating."
I've used a Redline additive called 85 Plus Diesel Fuel Catalyst going on 20 years for the 4 diesel vehicles I've owned. I have not had any engine issues at all including injectors / injection pumps with one 05 Duramax going to 220K miles. Rust killed that truck unfortunately. I guess the only way to know if something is working is the reliability of the engine. The product also contains Redline's ester synth oil to lubricate the cylinder walls and it also has a cetane booster. It has been a great product and would recommend it highly. In terms of oil additives, I have not used any to avoid ash clogging up the DPF. Any oil additive will end up in the combustion chamber to be burned off and if that becomes ash, its devastating to DPFs. DPFs can only burn off soot. Ash just lingers and clogs up the filter leading to an early death. If you're deleted, use Bestline Diesel Additive. Go to the YouTube channel "Project Farm" and watch the Bestline video. If that doesn't convince, I'm not sure what will. The guy on Project Farm is awesome!Does anyone plan on using or are already using any oil/fuel additives in their Duramax such as Zmax, Hotshot or similar products?
