Carbon buildup

[Newbie777]

Hello,

Has anyone looked at carbon cleaning on their LS cars, specifically LS 600

Thanks

Do you mean cleaning a carbon buildup out of the engine or the catalytic converters?

I recently bought some Cataclean Petrol Fuel and Exhaust System Cleaner Catalytic Converter Additive from eBay.

Bought two bottles and the engine certainly ran better after I used them.

The service guide for the LS430 does tell you to use a fuel additive like Red X regularly. In fact Lexus sell there own version.

I use Cataclean before each M.O.T. test. I have never failed the test on emissions.

Today I used Millers fuel additive and also had the car decarbon (ised?).

Will see how she runs, especially on the motorway.

Runs smoother and quieter, along with new air filters, mpg has improved too, on motorway  now showing an average of around 30mog at 70mph
