79jasper But it's not always wear causing stiction in a 6.0 injector. Many times the spool valves could be cleaned.

The diesel extreme works, but only supposed to run it once every 6 months.

You can't replace wear with chemistry. It's injector solenoid wear that causes the stiction in electronic engines.

LMJD It's always been agreed upon by diesel mechanics and diesel engine reps that black oil means the oil is doing its job. I remember years ago a few people requested Havoline and it would turn black so quick a few people later accused the shop of not changing their oil, and this was in gas engines. Long time back, but I remember any life-long Havoline engine we tore down the tops of the cylinder heads were amazingly clean, no sludge whatsoever to be found.

79jasper Yeah, but that'll be harder on your bearings.

2000F250-7.3 It has helped my 7.3 clean some of the coking out of my turbo and injectors. But the key to a 7.3 is use good filters and change the oil every 4,000 miles.

Right, that's all most of that stuff is.

ArcticDriver The post might have been saying that he used Hotshot when he bought the truck and his more recent oil changes are not as dirty.

79jasper Yeah, something else going on. Lol or something hes not telling. (Like a bypass filter)

Hotshot would have nothing to do with cleaning the oil. Even their web site says nothing about cleaning the oil.
Couldn't agree more, Bugman.

Randy 4614 I put the Hotshot In my 99 7.3 when I bought it this past spring. It is amazing how clean the oil has stayed. Not the normal black diesel oil that you cant get off your hands. So Yes I say it works.

RT Some 6.0 owners report injector stiction being an issue and having luck with this product. Never seen stiction on a 7.3 DI and no way on an IDI.
