I treated my CTT to new Mobil One and a full quart of Tufoil. Now, it runs much smoother and idles slightly slower. The turbos rev better.

From here forward I will be adding 8 ounces of Tuffoil to 10 qurts of Mobile One. I was shocked when the beast ate two 5-gallon 5-40w containers of Mobile One and I could only squeeze in 16 oz. of Tuffoil. I had to wait & drive about 700 miles before I could fit in the other 16 oz. of Tufoil.

In the past I used Tufoil on three other cars. One can expect better cold starts, slightly better performance and slightly less fuel consumption.

 

Warning: Do not treat an engine with Tufoil until it is broekn in and the rings have had ample opportunity to seat.

 

FYI is says on the Tufoil website not for auto tranny. "Tufoil brand engine oil treatment for all gasoline, LPG and diesel engines. Tufoil is the world's most efficient lubricant as recorded in the Guinness Book of World Records.

They Probably mean do not poor into transmission oil... but it's ok in the engine oil...

 

I only put this is with my oil--never anywhere else.
