I mean, obviously the premium spool valves are going to last longer and are a better design. I personally wouldn't spend the money but that's up to you. New valves and running hotshots or archoil in your oil will do just fine.

On a slight side note, Warren won't warranty your injectors if you are using T6 rotella.

I've never heard of Warren before........what's the story on the T6?

 

Hard to say, a while ago there was some talk about it and I can't remember the specifics, I think Warren claimed that T6 had some component in it that led to their spool valves failing...but other companies don't claim this. @bismic probably remembers better than I can lol

If it were me, I wouldn't be shopping from someone who is so strict about their warranties. If a company can't make a product that can be used by the majority of the population, they shouldn't advertise it like it's high quality. My opinion though, they are solid injectors from seeing what pops up on here. I haven't seen a post about warren injectors failing, I'm sure other people can agree with that.

I will have to read some of these posts. I have Warren injectors and no problems yet but I guess time will tell. When I ordered them 5 years ago, the customer service on the phone was great and I had a time crunch to get these injectors. No extra charge and they got them to me freakin fast.

 

Holders or Full Force gets my vote. I’ve read of too many Warren issues. I’ve logged a butt ton of miles on Holders and Full Force injectors in my 6.0 and 7.3. No issues with either on either truck.

 

As years pass, FullForce seems to be pulling ahead in the category of fewest problems (just my observations from forum posts, and this only an opinion). Some of the people in the early days held them up in high esteem and they seem to have maintained a high standard across the years. My interest in this is driven by a personal purchase that I know is coming up shortly, lol.

 

Yes sir, I will say this, I have had great success with Holders and FF. Had FF and currently have Holders in both trucks (6.0 & 7.3) and although they run great, I would say both ran a touch smoother and clean on the FF. But no complaints with Holders.

 

Nothing is 100% ........... not all good news, and not all bad news.

 

I am sure there are better injectors out there but I am still in the belief that changing oil often and putting a treatment in the oil goes a long way in helping injectors.

 

WOW lol. What the fack could be in T6 oil that would kill injectors? 😲

 

Uh oh, looks like I fell into this money trap too, I just put a full set of wdi stock injectors into my truck and I'm now (making oil) so to speak😕
