Staff JAG1 Posted August 27, 2013 Staff Share Posted August 27, 2013 Been driving about a year after the 0216 code came up. It never came up again till a few days ago so I increased fuel pressure to 21-22 from 18 and throwing 2 quarts of 2 cycle with every fill up to help the VP.I have a significant increase in miles hauling the same heavy camper on the same almost exact 3 day long road trip sometimes going 3 times a year.. It's showing a little over a 1 mile per gallon increase to 15.3 from just under 14.:think:I thought the vp should give bad miles when the timing piston starts to wear (0216 error code), but there's no white smoke and no hard starts. runs really good.

Yankneck696 Posted August 27, 2013 Share Posted August 27, 2013 That code can be interpeted many ways. Could have just been a glitch in the wiring. Or, with the higher pressure to assist the timing piston, along with added lubricity/BTUs of the 2 stroke, you may be helping the piston along...Ed Link to comment Share on other sites More sharing options...
flagmanruss Posted August 27, 2013 Share Posted August 27, 2013 I felt the 2 stoke oil additive was good for about 1 mpg in my truck. Link to comment Share on other sites More sharing options...
Owner Mopar1973Man Posted August 27, 2013 Owner Share Posted August 27, 2013 A drop in cetane (2 cycle oil) helps with increasing BTU's. Possible increase in manifold temp could help with MPG's as noted between these two runs. Warmer air does improve MPG's. http://forum.mopar1973man.com/threads/8290-I-think-I-finally-caught-up-with-ISX-for-a-day-run!?p=80081#post80081 http://forum.mopar1973man.com/threads/8290-I-think-I-finally-caught-up-with-ISX-for-a-day-run!?p=80399#post80399 Link to comment Share on other sites More sharing options...
diesel4life Posted August 27, 2013 Share Posted August 27, 2013 Running different tires on either the truck or trailer? Any recent mods? Link to comment Share on other sites More sharing options...
Staff JAG1 Posted August 29, 2013 Author Staff Share Posted August 29, 2013 thank you fellow diesel fans for the thoughts....... I forgot to say.... it runs really good but I did get one stutter on the freeway. Just for a split second, it prompted me to do the key trick to see if 0216 came back and it did after not seeing it for a year.No stutter afterward for the rest of the 1300 miles left to go with the heavy slide-in camper . It does run good otherwise. No modes on the truck except the usual fuel system, i.e. big lines all the way, raptor 100 , no in tank screens, 90 gph pre filter. Filters were new btw.

cajflynn Posted August 31, 2013 Share Posted August 31, 2013 You probably have a dirty fuel filter. Best mileage adder there is. Link to comment Share on other sites More sharing options...
Staff JAG1 Posted August 31, 2013 Author Staff Share Posted August 31, 2013 Thank you..... I think the engine is just getting broke in while the VP is on it's way out. It's got 75,000 miles on 'er now sooo.Oh yeah... I almost forgot....I put in one qt. of synth 2 stroke an one qt. of dino 2 stroke. Try it you guys might find better smoother mileage.

I have a quart of amsoil 2 cycle injector oil iv thought about adding along with my walmart 2troke oil I may try it Link to comment Share on other sites More sharing options...
Staff JAG1 Posted August 31, 2013 Author Staff Share Posted August 31, 2013 I have a quart of amsoil 2 cycle injector oil iv thought about adding along with my walmart 2troke oil I may try it Let me know what you find. As for myself I was surprised as to the extra fuel in the tank when I got to where I was going. I make that run a lot lately. With mixing the synth 2 stoke and dino 2 stroke (one qt. of each on fill up) It was quite surprised how well the truck ran. Link to comment Share on other sites More sharing options...
cajflynn Posted September 1, 2013 Share Posted September 1, 2013 Let me ask a dumb question. Do you add 1/2 gallon to your fuel total when figuring out your mileage? I have never been a big believer in 2 stroke oil. I might be wrong but my trucks made it pretty far without it. I always found fuel pressure to be a bigger factor in vp life than anything else. If a tank (34 gallons) of fuel cost $120 ish and you are adding $15 in 2 stroke to it, you have to get 10% better mileage just to break even. At least with walmart oil at $12 a gallon you only need to get a 3% increase to break even. For reference, a 1mpg increase on a 20mpg truck is a 5% increase. I really just don't see what the gain is.I am aware that some people believe the vp44 needs the added lubricity from the 2 stroke oil. It has not been my experience that my vp44's lasted longer with 2 stroke than without. Link to comment Share on other sites More sharing options...
