Have always used Power Service in the past with a vw TDI (amazingly always gelled when i used it, only when super cold though temps well below zero) Just curious if people still like Power Service. Recently hearing great things about Howes Lubricator, having trouble reliably finding it though.

Now I have a 03' LB7, can understand gelling with that tiny vw diesel, but how about peoples experiance with the Duramax? Well conditioned fuel, any problems? I would think that this large of an engine should be able to return enough fuel to the tank to warm the tank a little like a large highway truck, would this be true?

New to this site, it is great. Used to belong to a tdi site that was identical in web design/appearance, wonder if they are related. Thank you in advance

Welcome to the site..As for your question I still use power service in mine about every 3rd fill up. I have never had a prob with it gelling be sure you are using the winter blend in the white bottle. I love the stuff my truck runs better win I use it.

I use power service as well, every fill 1/3-1/2 bottle. Tried many others and prefer power service. Truck is stored through Canadian winter in open ended garage , started once a week and always fires first try - not plugged in- never gelled. Runs smooth, tows great.

That's what i like to hear. Power Service is so easy to get around here. Of course all the diesel is cut this time of year too, but after my experiances with my vw i am always a little leary.

Do either of you have a pyrometer installed? And if so did you put it before or after the turbo? Seems like everyone here puts it before, and to me like asking for something to travel through the turbo. If not shavings, than later the thermocouple itself. What do you think?

I'm with Paul, 1/3 to 1/2 bottle every fill, never had one problem. Make sure it is the white bottle for winter, I don't believe that the Diesel Kleen, in gray bottle, has anti-gel properties...

I'm using Stanadyne performance formula - no problems yet when it's been -1F but the truck is in a garage at night and I have both upper and lower factory winterfronts on - don't think it would Gel in a 12 minute drive to work anyway.

x2 on the Stanadyne Performance Formula........ I love the stuff, though I don't see near as cold of winters as some of you guys do though.

Stanadyne Performance for myself as well. I buy the gallon jugs and re-fill a couple of the single shot Stanadyne plastic bottles for quick filling.

As for the question as to where to find Howes, the local Flying J here carries it. No idea on it's performance though.

you get a more acurate reading before the turbo. ive heard here that you lose 100-200 degrees if it is put after the turbo. if your worried about shavings, take the manifold off and drill it. ive never heard of a thermo. breaking off. may have happened, but not that ive heard.

Ditto..:D

-14f this morning and truck sits outside. Mine ran just fine without any gelling. I use stanadyne. I think 12min would easy be enough time for it to gell. I actually passed 2 people this morning on the way into work that gelled up. The first one was a gm diesel and the second was a OTR truck.

Exactly what I try to do. I run #2 (not artic becasue it comes from the truck stop where the trucks fill #2) with stanadyne and try to refill the jugs also. When its this cold out I usually end up just throwing the little jugs out rather than try to deal with them after they are empty. I have a case of the little one shots in the garage. One thing to keep in mind also is that most additives have to be above freezing prior to putting them in the tank.

I recently gelled using the recommended double dose of Power Service at around -15F. Put it in a garage, warmed it up and added more, and all was ok. My filter had about 32% life left at about 9500 miles though. Hasn't got that cold since, but next time I'll just add more I guess.

been down to -17 and going to be in the teens for highs and around 0 nighttime. I use a lubricity additive only(not sure if it's an antigel or not). Never had fuel problem issues and only 1 clogged filter in my life(stalled under full throttle).

Anyhow I'd be more concerned about the poor quality winter fuel you seem to be getting rather than heavy dosing with PS. Not that it's bad, but maybe the fuel you're getting is sub par.

white bottle power service,double dose when i leave it parked in the top of idaho for a couple of months,no problems. i park outside, it gets well below -0. i hear that ulsd gells easier than the older fuel.
