Newbie777 Posted November 15, 2023 Share Posted November 15, 2023 Hello, Has anyone looked at carbon cleaning on their LS cars, specifically LS 600 Thanks Quote Link to comment Share on other sites More sharing options...
John N Posted November 15, 2023 Share Posted November 15, 2023 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. 1 Quote Link to comment Share on other sites More sharing options...

I have never failed the test on emissions. 1 Quote Link to comment Share on other sites More sharing options...

Newbie777 Posted November 30, 2023 Author Share Posted November 30, 2023 Today I used Millers fuel additive and also had the car decarbon (ised?). Will see how she runs, especially on the motorway. Quote Link to comment Share on other sites More sharing options...
Newbie777 Posted December 13, 2023 Author Share Posted December 13, 2023 Runs smoother and quieter, along with new air filters, mpg has improved too, on motorway now showing an average of around 30mog at 70mph 1 Quote Link to comment Share on other sites More sharing options...
