Has anybody seen one of the injector guru's answer one of the many posts on fuel additves. I would like to see one of them answer to see if there is an advantage.

 

I use ashless 2cycle oil at a ratio of 1 oz per gallon of fuel, plus a cetane booster. Have been using this mixture for over 20,000 miles with fast starts in cold weather. The oil is good for injector lubricity.

 

I have used Opti-Lube XPD since it came out on the market, no problems whatsoever, even got a little fuel mileage gain.

Another GOOD additive is Power Curve Formula XP-12, Diesel XP Fuel Enhancer. I have a friend who is using it, same results as I have been having, GOOD results. http://www.powercurveinc.com

5% biodiesel better lubricity than any additive....

 

Don M has posted repeatedly that water is the main issue with CR injectors. He recommends a demulsifying additive w/o alcohol usually.

I can personally say that I agree. He did my injectors a few months ago and said they were pristine when he got them. I use Stanadyne Performance in almost every tank. It's not all about lubricity, so biodiesel still needs a little help.

 

Just get good clean fuel and you don't need any additives. That and filter changes, you should be fine.

 

You can go to this site [mopar1973man] He has done his home work. When you get to the web site look a round .

 

Why do so many think they need put in fuel additives including 2 cycle oil? My brother an sister in law both drive OTR and drive over 200K a year and they have never used fuel additives of any kind and they have yet to have injector problems from ULSD in there 2005 truck.

 

What was explained to me was trucks that were built prior to the ULSD mandate relied on sulpher as part of the lubricity. The cetane booster is to boost the cetane up just like running a gas engine with 11-1 comp. ratio and running on todays gas, you would want to up the octane number. The diesel we buy is 40 cetane minimum but the engine would run better up to 55 cetane. You will get less knock with the higher cetane numbers.

 

yeah what about two stroke oil i hear it is good?

 

Lets see if I can direct you to a study on fuel additives that helped lubricity or made it worse.

I made one error the truck is a 2004 not 2005 so is was made to run on the old LSD and not today's ULSD. Like I stated before they have yet to have a fuel related problem from lack of lube in diesel they burn and if anyone is going to see problems its those who put many thousands of mile on a diesel engine every week. To help some of you to better understand they burn 175+ gallon a day, don't use any fuel additive and in the past 2+ years of using ULSD they have not had a single fuel related problem from ULSD. The only one's who I can see having any problems when we first switch over to ULSD is those few who have the VP pump that relied 100% on the diesel fuel to lube its internal parts and why they now put lube back in to diesel fuel.

 

You do know that the test you linked to the test was done on refinery run diesel fuel that you or I could not buy so it really has no bearing on the fuel we could buy back then and it still has no bearing on the fuel we buy today.

JMHO.

 

That's not necessarily true. If the fuel at the station never had it's additives package put in, that's exactly what you're getting.

As far as fuel lube goes, sulphur is NOT a lubricant. We do not, have not, will not, cannot rely on sulphur as a lubricant. The process that is used to remove sulphur also removes the lubricants in the fuel (paraffins, sp?).

Back on topic. Is there any other additive such as stanadyne that is a demulsifier? Power service? Howes? Stanadyne isn't readily available near me.

Based on what I've been told (I have family member who haul fuel an have for the past 10 years) the tank farms are run buy computers, the computer makes sure additives get added to the fuel as its being loading in the tanker before it goes out to the station for us to buy, thus unlike the old days when getting the additives mixed in to our fuel relied on humans to open and close off valves and thus additives may or may not have gotten mixed in to the fuel.
