Would a pre oiler make any difference on injectors? I thought it just effects bearing surfaces and stuff like that. My worry with additives is about the Hydronic/Airtronic systems I have. They (Espar) suggest not to use additives. Their worry is not about the engine, rather their systems. I'm no expert at all when it comes to additives, oils, or oil systems, but read that lubricating the injector system through the fuel system is very important on the 6.0 engine. I have already had a injector failure. Fords additive claims:
>Designed for diesel engines.
>Boosts the octane rating and fuel ignitability for improved engine starting.
>Increases power.
>Smoother engine operation.
>Improves fuel economy.
>Adds lubrication to the fuel to reduce engine wear and is USDL compliant.
This all sounds typical to all additives but because it's a Ford product, it reduces warrantee issues Ford might try to claim if I'm using other products. At least they won't be able to argue that. The Ford shop pointed out that much of the carbon build up in my manifold and the failed injector was due to failure to use
their 
additive. Because Ford claims that it reduces carbon build up and it improves ignitability, my hope is that the additive will also help the Espar products rather than hurt them. My Espar products have also been plagued by carbon build up. Maybe it's a leap of faith but I'm gonna give it a go and use Fords product.
FWIW we don't use pre oilers, additives, twin filter systems or synthetic oil on our work fleet and don't have many major failures. The shop does oil tests and typically changes the oil around 10-12K. In the past most problems have been turbo charger failures on the Ford engines (7.3 & 6.0) but I think it's more due to how we drive the vehicles. With the emergency vehicles, we don't have time to warm up the engine and a lot of the employees just don't care anyway. With the response vehicles, they have given us remote start and at least now I can let the engine warm up while I put my cloths on. From what it seems this has helped; no turbo failures yet. I've gone through two 7.3's and no turbo failure. The two 6.0's we have in
our dept have had the turbo's changed (one 3 times) but after the guys started to warm up and cool down proper they haven't had any more problems. Of course time will tell. Like I said, we drive em hard.
As far as the pre oiler, the guy that had it lived in Washington's cold climate, something I don't really have to deal with. When I'm in freezing temps with my van I use the Hydronic to pre warm the engine, and even though it's probably not near as efficient as a pre oiler, adding one is low on my list. For now I will depend on synthetic oil to help (I hope) with bearing wear. It still seems like a good idea to get oil to bearing surfaces on cold startups.
