do any of yall put 2cycle oil in with your fuel? Is it the one oz to one gal? Just pour it in at a full up?

 

No. If someone told you to do that find someone else. Oil in a diesel is the life blood - thinning it out with gasoline or something else is not sometihng you even want to consider.

Adding it to the fuel can be a way to get better lube in older trucks running ULSD. Your 2006 DOESN'T need that and you will do more harm than good as a result. Don't waste your money. If you must run a real additive like Howes or PS.

 

I'm sorry I'm a dumb ***, in the fuel I meant. Not in the oil

 

I've been running 2-stroke in my 06 since new and have had no problems! I've seen a 1.5mpg increase, smoother idle and that annoying ticking noise seems to have gone away. When I don't add the 2-stroke the ticking comes back. The engine seems much happier with the 2-stroke and I get smoke!

I add a quart @ every fill-up and that seems to be about the right mix.

I've been running 2-stroke in my Dodges for years now. Make sure you get the TCW-3, no/low ash oil. NO SYNTHETIC'S! I buy the walmart brand. It's the cheapest I've found.

 

Well Buck you must be on of the lucky ones. From my experience running any sort of "stuff" in the tank of an 2006 and newer results in more trouble than it is worth. Esp. on the 6.7L...

 

I've been adding 1 qt. (32oz.) at every fuel-up (20-25 gal). That's a little more then 1 oz. per gal. Also, I get the Supper tech Outboard 2-cycle TC-W3 engine oil at Wally World, cost $8.89 per gal. works very good for me with no problems to date.

 

i know a guy w/ a 6.7 who tops off his filter w/ atf....hes crazy

 

OMG, some people really need to give their heads a shake. $40 to 70k trucks and you put that stuff in there because that's what we used to do in 1980! Your friend should be educated...

oil as an additive in a 2nd gen 5.9L is a good idea if you don't trust the source of your fuel. All ULSD comes with an applicable level of lubricant to compliment all new trucks. 2006+.

 

The main thing that 2-stroke does is, it puts the lubricity back into the fuel that they have removed over past years because of the tree huggers. 2-stroke oil is designed to mix and burn with fuel. I haven't had any issues or heard of any issues that have resulted from running 2-stroke. I've heard nothing but positive results from the use of 2-stroke.

Now, on the 07.5+, 6.7, yes, I would see why there would be a problem because of all of the emissions crap.

 

Buck,
I know what it is supposed to do - others may not so that's cool. The thing is all major suppliers (Chevron, EXXON, Esso, Shell etc.) all put a level of lube back into the fuel at their tanks that generally exceeds the governed minimums which makes adding TCW-3 sort of pointless.

I'm not saying doing do it but by using a good helping of PS or equal before a long trip will do more for you than adding this per fill will in my opinion.

Again, this is my opinion and first hand experience with any truck 2005+.
