Additives - Question

I've been told that Stanadyne is an excellent additive, but I see a Injector Cleaner, a Diesel Fuel Additive, and a Lubricity formula. Is anyone using these? Do I need all 3 or will one of these be fine, if so which one is the best at helping keep engine clean and running smoothly? Thanks for any help/suggestions.

The VERY best additive to add lubricity is to buy yoru fuel from a station that has Bio in it. Even B5 adds more lubricity than any other additive you can buy.

In addition it is an excellent fuel system cleaner.

I haven't seen a pump marked with bio component in several years and even then the guy working the station didn't have a clue what was put in the tanks last shipment.

I don't use Stanadyne but just reading up on their products I would pick the red label Performance formula.

They launched their new Synergy Diesel Efficient fuel campaign last year.

It's a 2018-2019 roll out across the Country (according to their site), so it may have just hit your region.

I asked if it had bio and said a month ago they got syn,no bio in it.
Exxon sight says detergents ,nothing about lub.Sight seems to jump around a lot .
Iíll have to look at it more later .

Fleet has an old 2005 vid of bio showing no water separation .I didnít know that.Man there water test strips are expensive.Like 180 for 10.

I work at a refinery. We are required to put bio in the shipments.
As for lubricity, different regions have different lubricity specs. Some don't have any specs.

Bob, is the bio requirement from the State? At one time Texas mandated quality diesel that pretty much matched CARB requirements.
