[ItsNo4RE]

is there one brand that's better than others in terms of quality? brands to stay clear of?

Most may say not really. I work in the industry, my top two spots are Shell and Meijer. Both rated top tier fuel.

I am starting to understand that Shell uses different fuel detergent and additive blends on their 93 octane and a bit less of their additives on mid grade and base grade. Meijer uses the same across all three grades because they sub out their freight regionally and don’t have Time to train the drivers and depots on how to add what.

I haven't noticed or even heard of diesel being different across brands except for one and that would be Propel fuels. In my Duramax, I run whatever is cheapest or most convenient. Now Sam's Club or Costco are the cheapest and most convenient. For a while, Propel was the most convenient for me and I liked it being B20. They've since changed their diesel and I have not tried their new Diesel HPR formula since buying my Jeep. It sounds good though.

Lubricity is what I think matters most - does anyone know the Rockwell scale block hardness for this engine? I could narrow down some options possibly.

Just make sure it's Top Tier.

It's not a two stroke. Fuel lubricity is for the injectors not the block.

Yup. Says right there, "Fuel system". i.e. Fuel injectors.

I think it is more important to go to a busy station rather than specific brand. The older the fuel, the better chance of water and condensation getting in.

Also remember unless it is a company owned store many gas station are franchise or independent. Just because it says Shell many times they will buy whatever is cheapest “off the rack” as they call it.

This is not true, Especially with Shell, all Shell branded stations are linked to a telemetry system. So their Shell “rep” sees their tank levels at all times. If a rogue operator of the station brings in something other than a shell truck from their depot, the Shell rep can see it right away. They pay fines based on their contract.

So no, this isn’t something that happens a lot for their stations.

Other stations that are independently owned and unbranded, absolutely this happens.

Sometimes even with Circle K and Speedway stations that are remote, they’ll use whatever they can get.

Buy from a station that sells a lot of fuel and "turns over" their product. Diesel that sits can grow algae in it or get water in it or other nasty shit that will cause fuel system issues. Modern diesels are very sensative to bad fuel.

These aren't 70s Mercedes diesels that'll run off used french fry oil!

ok if you say so then it must be fact. Certainly not going to share the actual locations that I know for a fact this happens. It may only be a few examples but I assume if they are doing it then others are as well.

I think with diesel fuel the best bet is to:

1) Buy fuel at a station that's well maintained, i.e. somebody is changing the filter in the pump on a regular basis and there are diesel trucks filling up there frequently.

2) Use a quality additive such as Hot Shot's EDT so that you can elevate cetane and lubricity and protect valves, injectors, and most importantly that Bosch CP4.
