I was talking to a guy who works at a Chevron refinery in Richmond CA and he said something about new federal regulations on diesel fuel. The sulfer content was lowered a great deal and he was suggesting fuel lubricity additives if I was buying cheap #2. He said Chevron was adding lubricity agents and additives weren't need if buying Chevron #2.

What are some good additives? What do you use if you add additives?

thanks

Moved to fluids discussion.

Most refinerys add additives.

You never know if there are additives or not without testing.

Use lubricity formula at a minimum.

The old trucks are allowed to use more sulphur in the fuel. They are exempt from the low sulphur laws.

It may be illegal to put additives in a new vehicle that will add more than the allowed amount of sulphur.

Standyne. For the last 2 years I have been putting it in the tank just prior to fill-ups. No problems.

ULSD's Lubricity

Lubricity is the other big concern from a performance standpoint. As new vehicle fuel systems move to higher and higher operating pressures and tighter and tighter metal tolerances, fuel lubricity is becoming more of an issue. The lubricity of the current on-road LS No. 2 diesel may or may not be enough for these new systems. To correct this, last year the ASTM adopted a lubricity specification into the D 975 diesel standard. The requirement is a 520 micron maximum wear scar diameter on a special instrument called a high frequency reciprocating rig, or HFRR. It took the industry some time to get this accomplished, but by now, nearly all U.S. on-road diesel fuel has sufficient lubricity or is injected with lubricity improvers at the terminals while it is being loaded into transport trucks.
The hydrotreating that removes the sulfur will also result in lower lubricity with ULSD. Aftermarket additive manufacturers and biodiesel proponents have been pushing their products as ways to correct ULSD's poor lubricating properties. This is no longer necessary as terminals will continue to additize the fuels to meet the ASTM specification. The bottom line is that the additized ULSD will have better lubricity than the unadditized LSD we have been using for years. Lubricity is not a concern with ULSD, but this goes back to the earlier point — if you want diesel, buy diesel. If fuel is purchased as kerosene or fuel oil, it may not have these necessary additives.

I say add the additive. Maybe the fuel has some/same/more than LSD fuels but know really know (by test) that ULSD has the additives.

Be SAFE!


**** JUST MY OPINION, others will vary ****

Most of the time I run B-20, don't have to worry about lub. with that stuff. But I keep Stanadyne under my back seat just in case I have to fill with ULSD. I would rather put Stanadyne in it myself just for the piece of mind. Better to have too much lub. than not enough.

Howes Lubricator--32 years and still truckin--get it at truck stops.

With the new ULSD my engine was pretty loud, I started using Howes which it did well. I found a distributor of B20, so I went and filled up. Man my truck is way quiter, have had no power issues, and MPG is the same. IMO biodiesel is the best additive.

Most refinerys add additives.

The refinery's don't add any additives. It is added at the terminal or distributor. They reason a refinery won't add additives is because they use the same pipelines and distribution channels to send home heating oil and other fuels that can't have the additives that are used for engines.

I won't put a lot of trust in that there's enough lubricity with the ULSD since it's so new and not everyone is on the same page so I always add some lubricity and anti-gel at fill up. I like Power Service or Hydrotex Diesel Kleen Artcic.
