Additives ... What do you use ... Why and When?

None here, imo all are a bunch of BS snake oil.

I used to use Howes anti gel but no longer. Had zero problems this past winter. When I can burn through 150 gallons a day it’s just cash going out the stacks.

I’ll save my money for beer

 

Snake oil most of them IMO.

Don't know of anyone who uses any regularly or at all.

 

I used Howes as well. Bought it by the case. Also filled my fuel filters with Howes every second change, it seemed to keep my injectors cleaner and it pulled stronger.
Winter I used it always including with blended fuel, any time the temp would be below freezing before the next fuelup.

 

What engine are you running and year ?

 

I run a gal of filtered used engine oil here & there. Gotta get rid of it anyways..

Or wally world 2 stroke if its on sale..

 

only what's recommended by manufacturer

 

As per RAWZE(Cummins Guru), I run 1 gallon of WallyWorld gear oil GL 5 at every oil change on my ISX 15. For fuel additive, I’ve ran a few but ended up with Lucas. Cheapest I’ve seen it is at Wally world. I try to stay away from B-20 fuel, but if I need to purchase it, I get minimal and add the Lucas. Other than that, Lucas about every third fill up or so.

 

Howes anti gel. Clear liquid.

Don't know when it came out for sale. First time I seen it.



The truck didn't get used much this past winter.

 

Nothing in summer and a number one blend in winter. No additives
