How much do you add to a tank?

I put 2 of those little bottles in...

More?

Less?

 

It was Lawn Boy if that makes a difference....

 

As long as it's ashless I've heard guys putting in as much as a quart per tank.

 

Crap, I don't know if its ashless or not... it was light black...

Do I need to do anything if has ash?

 

Most 2 cycle oil I've seen is ashless. It was only two little bottles I wouldn't worry especially since you've got a 12 valve (tuff little buggers). Just keep the tank topped off for awhile to dilute it just in case.

 

I'm running 32oz of TCW3 two stroke mixture oil every other tank.

i dump in 1 quart per tank. my mileage has sky rocketed way up.

 

I've dumped 2 quarts of Wal-Mart oil in my tank and it made the engine sound like a new engine.

 

A quart of TCW-3 does quiet the engine and seems to have improved mileage for me. I'm still breaking in, so it's hard to tell for sure if the increase is coming from the two stroke oil or engine break in.

I wonder how much if any sulphur is in the two stroke oil. I have people with 08s asking me if they can use it in their trucks.

 

LoneRanger,
I was asked that question last week by my Dad. I'm not a chemical engineer but I have been researching the subject. My thinking is ashless TCW3 would produce very little sulfated ash. Sulfated ash is a by product of noncombustible components in the oil, like sulphur, detergents, and metallics. These are the items that will clog the DPF.

2 stroke oil for outboard engines has no ash.

 

I've been running an ounce per gallon for about a year now. I keep pretty close tabs on my fuel mileage, hand calculated, and it has improved it some. It seems about 1/2 MPG. Most definitely made the engine quieter although not right away. Mine was noisier than my buddies '99 and now it is considerably quieter.

 

I just tried a quart inmy last tank, it sure made the engine quiet! Didn't put any in this tank and it has gotten noisy again. Think i'm gonna start running it all the time now.

 

Don't hate me for this, but will this also work in my Dad's '03 Ford 250 PSD? I want what's best for him despite his bad choice in trucks.

 

Yes...

I dumped 2 quarts in today... along with thte remainder of my PS...

I got a HUGE 50 mile bump in range from the last tank..
