The particle filter is a pretty recent invention that aims to remove harmful particles from the exhaust gases of modern diesels. It has long been seen as the miracle solution to these pollution problems. Nevertheless, it doesn’t work as well as intended and causes more problems than it resolves, which is why we will find out on this page when changing the particulate filter of a Lexus GX? . To do this, to begin with, we will find out what the particle filter on your motor vehicle is used for, and then when to change the particle filter on your Lexus GX.
What’s the purpose of a Lexus GX’s particulate filter?
So we commence our content with the rationale for this element not too long ago integrated into diesel vehicles. As we described briefly in the introduction, the aim of this filter was to fix the problems of pollution and harmfulness of exhaust gases from Lexus GX vehicles. Its operating principle is to store exhaust gases that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to bring about a second combustion that will finish burning and eliminate all these carcinogenic particles. Sadly, to reach this very high engine unit temperature, you have to be on the highway or have your Lexus GX engine unit revving up. So we have noticed as time passes that cars that are mainly on short trips or in the city do not enable the particulate filter to burn these gases and we will observe in the next section that these problems can force you to change the particulate filter of your Lexus GX .
When to change the particulate filter of a Lexus GX?
In this section we will find out what you are certainly drawn to here, whether it is necessary to change the particulate filter of a Lexus GX and if so, when?
Is it necessary to change the particulate filter on Lexus GX?
There are 2 types of particulate filter for cars, a particulate filter with additive, which does not matter the Lexus GX, but which needs to be recharged every 120, 000km with an additive that enables the regeneration of the particulate filter and therefore to burn all those harmful soot. The second one, the one we are keen on today, functions with precious metals that will create a chemical reaction at high temperature and bring about the regeneration of the filter and the evacuation of the carcinogenic materials. Nevertheless, as revealed above, it necessitates very high temperatures, if these are not reached the filter will clog. If the filter is not regenerated manually, drive at high speed for about 20 minutes to reach this temperature and thus regenerate your filter, you will clog it and risk damaging your turbo, your EGR valve or your engine unit. If you need to clean the EGR valve of your Lexus GX as a result of your particulate filter, do not think twice to look at our article on this subject to find out what the process is.

If you don’t frequently take the motorway, we recommend you, every month to drive 10 minutes on the motorway at least 3000 rpm . In spite of everything, the current particulate filter have not been well designed and remain problematic, it is considered that as a result of the lack of a sufficiently regular temperature rise and other design problems, you should begin planning to change your particulate filter from 200, 000km if you have a use of your XX that is more urban and a little more if it is mixed .
