Diesel additives by Lake Speed Jr.

If this was posted earlier please delete it. I couldn't find it when I searched but not sure what to put in. Maybe start a Lake Speed Jr thread? LOL

Now of only more stations would carry a higher quality diesel fuel.

I can't get Exxon/Mobil diesel near me, so I will keep using Hotshots EDT and convince myself I'm doing something good for my diesel.

Not sure why Lickity Split 10 speed videos are allowed to be posted but not Project Farm? At least PF says his videos are for entertainment purposes and DO NOT simulate an internal combustion engine testing, or complies with any ISO testing. Far cry from Lake Speed, who makes crazy statements and hasn't back them up with his "science." The fanboyism for this guy is unreal on this site.

Love the clickbait title cards and soy boy face on the videos. /s

The fix for reducing carbon build up and exhaust particulate is make a cleaner burning fuel. Then there wouldn't be a need for additional additives. But to me big oil doesn't want to spend the money to do so, just keep making the CEO and others at the top wealthy. Which is living the dream.

What could big oil do differently to make a cleaner burning fuel?

I’ve seen industry experts say the Diesel can vary widely, from region to region and refinery to refinery…with some using different levels of de-waxing to significantly change cetane while impacting additive abilities.

It would be great to know what’s what.

Premium Diesel needs more availability.

LSJ talks about how most US diesel is short on additives
(First 12 minutes is enough) …

2017 Top Tier Diesel started but then no one wanted to deal with it. 2019 "Premium Diesel" launched by another body that seemed to gain more traction.

So far I've only found Cenex offering it but only at select locations that are way too far away from me. "Cenex Road ranger" is what they're calling their Premium Diesel. Until this is more widespread I'm using Power Service additive.

I had high hopes for our new Costco to carry diesel but that dream died when they opened.

Decent video this time. Wish they would have done 128:1 vs 500:1 for the 2 stroke oil.

People absolutely expect too much from dumping in a small bottle of additive in a large fuel tank.

I do the same, though I’ve switched to Archoil now. My 3.0 duramax manual states to use an additive if top tier diesel isn’t available. Considering I don’t have a Costco within 50 miles I’ll continue with an additive.

ETA: I have Exxon available, but with my fuel rewards at Kroger I almost always have $1 off/gallon so an additive treatment every tank is a heckuva lot cheaper

I can't disagree. The Hotshots EDT that I use only calls for one ounce per 20 gallons of fuel. I've always wondered how so little could accomplish anything.

Bump the cetane level?

I’m just looking for a little cleaning, lubricity and a cetane boost. Maybe I’m expecting too much, but I don’t think so. It’s what I’d expect to get out of premium diesel if I could get it.

There is overdosing and bumping the dose.............just saying

Hm...very weird concentration of 1:500 chosen for the TC-W3 .

Curious to see how these additives and the two oils performed in some Premium Diesel blends and in FAME-treated Diesel in various concentrations - would not be surprised if some strange interactions occured leading to some really modest (or nil or even negative) lubricity improvement .

All fuel going into our vehicles should be top tier....with no additives. I use Power Service Grey bottle religiously.

It does seem that with some reasonable expectations, some useful gains can be had with additives in diesel

I run Hot Shots EDT as well and was really surprised at how much difference it made. Very cost effective per dose, I happily run it. There's no premium diesel around here.
