In post #26 the Chevy 6.5L I'm talking about is the FIRE TRUCK I drive! It the only way to keep that beast running right... Other than that it trips the SES Light and reduces the power by half!

 

1. I would go with 2 stroke oil over black (WEO)...

2. Yea... Just dump in your quart and fill the tank (20-25 Gallons)... You'll hear the difference in about 5 miles.

As a matter of fact I dumped in 1.5 quarts this morning. I forgot to add it with the last tank load... Boy it got quiet... The Cummins is going WEEHAW!

 

I've been doing this in diesels for 12 years since I owned my 6.2 diesel Blazer that I bought from my old man.

 

You on any 6.5 forums, mopardude?

I guess you got to becareful of what you post you might get everyone posting a response to you post!

Which I've already answered in a PM... Maybe I soon of posted that... Oh Well live and learn...

 

i ran 2 stroke a while and now i use 30wt non detergent every fill-up but will use 2-stroke if no oil available. power increase noticeable on my 1st gen and mileage back up. not much smoke either

 

I have about 5,000 miles on my truck now and at around 3500 miles I tried to use 16oz of 2cycle oil from Walmart (Ashless) and half a bottle of Power Service- - - - - - - the truck ran slower/felt like it had less power, puffed black smoke, and got worse mileage?????? What is the deal? I'm considering running the 2 Cycle oil by itself for a while and running the PS about once a month to clean the injectors. What do you all think?

 

After only a few days of this, I can't call myself a pro, and why it seems good in some, but not in others. However, I did read another thread in the archives where someone made the point of the outboard oil being designed to burn, and burn clean. Motor oil is said to be designed not to burn and will leave more deposits. True ?? I dunno, but it makes sense to me, and I think I'll stick with the outboard oil.

Whats so great about the outboard oil? Wouldn't any 2 stroke oil be designed to burn, regardless of what application its in?

 

that's a good question, i have never tried just 2 stroke oil...it will probably work just as well. when i run out of what i have i'll try some

 

Ashless 2-cycle oils are just that - they have a sulfated ash content well below 0.1%, and sulfated ash is what's left behind after the oil is burned off.

4-cycle diesel engine oils typically have a sulfated ash level of 1.0% or higher, so they would leave behind over 10 times as much deposit as an ashless 2-cycle oil.

Yup!
Top quality oil companys make two types of 2-cycle oil.... liquid cooled 2-cycle oil and air cooled 2 cycle oil. Easier & cheaper to make air cooled 2-cycle because cylinder head temps are higher so the oil burns more easily.
Many more additives in liquid cooled 2-cycle oil (rated TCW-3) to make it burn more cleanly at lower cylinder head temps.
Since diesel engines have much higher cylinder temps than 2-cycle motors, I think either type of 2-cycle oil would work well, if your inclined to add that sort of thing to your CTD. Either one is much better than engine oil, IMO.

what he said

 

I put my used engine oil in,seems too burn.
