I just filled up and the guy next to me put in 8 ounces of 2 cycle oil in his tank as an additive. he said that the new low sulfar fuel has bad lubrication and he uses it to help with lubrication. Just wondering if anyone else uses it?

 

The search function is your friend. This topic has been beaten to death.
I run it at 1oz to a gallon.

 

Sorry man I haven't been on this site since 2007. Just starting to get back into things.

 

No need to be sorry. You had a question in need of an answer.

I have been using Walmart 2-cycle TCW-3 oil ever sence the ULSD hit the market. I use approx. 2/3 oz to a gallon of fuel.

In a research that was done on lubricants 10% bio was best and 2-cycle came in second.

If you have a cat you may not want to use 2-cycle oil, not good for it.

 

Papaduck, I have a Cat in my 2003 SO and have been using 2 stroke for over a year. What problems will it give my cat?

 

Run it here, 16oz to a tank for me.

 

I have no experience as I have no cat, but have read that 2 stroke can clog it. I would think that if you keep it hot it should be OK.

We are just starting to get cats on the trolleys at work. We drive slow and never really work the engines hard, and they do a lot of idleing. We have both Cummins and Duramax. The Dmax has a cleaning cycle to clean the cat. We shall see how they work out.

 

Gotta remember we can dirty up the fuel a bit. 2007 and older (non-6.7) were designed to be run on LSD, not ULSD. Unless you are dumping crazy soot into the cat you will be fine.

I do agree with the idle thing though, diesels in general dont like to idle. Run that thing with a load, service it, and it will run for ever.

I recently just ran my first tank full of TCW3, engine seems pretty happy with it and the injector noise has decreased alot. I have been using other additives in the past also.

 

Seriously, if you don't have first hand experience don't shoot something down. You know " i heard from a friend of a friend's uncle had a problem." Not good info.
I know first hand hundreds of people on this board and others running the 2 stroke for years and years without a single problem.
Show me one thread about problems with 2 stroke and a clogged Cat.
Here's a couple threads i found with the SEARCH function.

Rookie, if you cannot get biodiesel,which is essentially free (same price as other diesel around me anyway) and the best for lubrication and cleanliness of fuel system, go to Wally World or wherever and buy a gallon on TCW-3, the ashless 2-stroke, put a quart to a tank, you should be set then. Good Luck

 

Its a great additive for the 98-02 trucks. There have been mixed results on the HPCR's.. Personally at 10oz a tank it was gumming my exhaust brake up.. and saw no other improvements, so I quit using it.

 

I'm running it in my 06, my 92, and my Massey Ferguson tractor, no problems at all. I tried an ounce to gallon in the 06 but it seemed to lose power, felt like it was always under load. I kept backing down & got to 12-16 ounces per tank.

 

By the same token thousands of people do not add anything to their fuel and do not have any problems.............and they have more money in their wallets.

 

It's all personal choice. If you don't want to run it - don't. I have and do run it with good results. It costs me an extra .50 to .75 per tank, and I am ok with that. I have seen no negatives at this point, and it is a noticable difference when it's in the tank. Much smoother and quieter.

 

My cousins diesel engine in his 1968 John Deere has been running ULSD for 3 years without any problems so it can't be as bad as some claim it is. If you want to try it out go for it, some like it, some see lower mpg when using it and as its been said a lot of people don't use anything at all and have no problems from burning ULSD.
