I run Diesel Kleen myself as it is available everywhere.
Main advantage i think is lubrication for your pump and injectors i believe.
I also run it for the Anti-Gelling up here in the winter.
Yup, lubrication is the main benefit. Also antigel in the winters, and some offer a cetane boost as well.
Personally, I'm a HUGE believer in stanadyne. Thats what GM recommends, and it's really great stuff. Hard to find, but very good stuff. I've got a sticky FPR, and just the standard dose of stanadyne keeps it 100% quiet. Takes a double or triple dose of diesel kleen to keep it acting normal.
was using howes because it was on sale but then power kleen went on sale last week so i got 6 bottles of that. I HAVE to get better at adding it to each fill up because in the summer I always forget to put a bottle in the pickup
Edit: this last spring i used something from amsoil which i guess i didn't mind. I use amsoil in the motor and all my race motors along with the wifes car so I kinda like the stuff
The Optilube study is old (2007 if I recall). Most people rave about additives due to the engine running quieter or slight improvement in fuel economy. Truth be told most of that is psychological and cetane improver. Any lubricity improvements will be transparent to the end user as we can't measure wear in the injectors and CP3.
I'm not bashing Optilube, but they are a boutique company. It's like Amsoil tests that show them performing the best 99% of the time. It's just suspicious. Especially if you study lubricants like I do. My point here is "most" fuel additives will do something for you lubrication wise. Is this even beneficial?! Really the answer is probably not. With plenty of 500k fleet dmax's out there that haven't had a drop of additive, as most companies see it as having zero benefit especially with no ROI, it becomes more of a feel good product that certainly doesn't hurt now and then for the enthusiasts like us.
Just checked my balance rates today. All are running right around +/- 0-1 in park, highest in drive is +2.1 Before they were running in the 2-3's at idle and had two over 5 in drive. Makes me feel better since these injectors already have 50K+ on them.
Any chance that this stuff can go bad? friend of mine gave me a bottle of Stanadyne he purchased about a year ago and hasn't used will it be okay to use?
IIRC Stanadyne says good for at least 2 years unopened, but just may lose some effectiveness after that. Probably should shake them up in case they've settled some.
I tried Optilube XPD in my LML, and although it did quieten the engine noticeably, it caused much quicker DPF plugging, as the regen frequency went to two cycles per tank instead of just one. Also the truck slowed in the quarter mile. This is despite Optilube's claims of reduced emissions and improved power.
Stanadyne. Sold at local chev dealer and at local performance shop. Use the performance additive with cetane. Got it to add lubricity and fight gelling. The extra kick from cetane is nice. Have noticed a slight improvement in mileage. I'm sure it will improve once I get a new fuel filter more though ( at 12% now, hope adapter arrives soon!)
