i keep checking it every week and just today i had checked it , it shows above the low mark by little ( that mean it still consuming oil)
and i the cat is done around 2750 KM ( 1718Mi) when i had replaced the oil , i think this is abnormal consumption

 

i always used Genuine Lexus Motor oil only that certified by Lexus dealer

 

thanks marc for the advice , i will try it , i ahd chekced the service history of the car i had found the last service was recorded on 40K mi

 

thanks striker 223 for the advice
i will try it and cross fingers ,

 

this is striker 223 ?

 

So, if I use this stuff does it clean my fuel filter also?

 

Probably not lol!


Yes use that, it breaks up the carbon well without venturing into tbt ultra aggressive type of treatments

 

Before you add any of these snake oil treatments, add 1/2 qt of oil (and a second if necessary) and note the oil level. Check it every 100 miles. These cars usually don't burn any oil between oil changes.

 

It's not being added to oil, it's being added directly to the combustion chamber via spark plug holes.

You then leave it for 4 hours per 90* of engine rotation to let it try and soften the carbon locking the rings up. B12 is a moderately strong solvent that won't cause to LS y issues even if you are stupid with it unlike some of the serious solvents. That's why I suggested it, I've had it work many times in many brands engines without having to run the risk of the strong stuff.

 

The oil I was referring to was the snake oil!

I wouldn't have thought an LS engine with only 80k miles on it would need cylinder decarbonization(?) In the old day, we used 2 stroke oil to accomplish the same thing. Don't know if it actually did anything but that was the conventional wisdom in the 1960s.
