The particle filter is a quite modern invention that aims to take out harmful particles from the exhaust gases of latest diesels. It has long been discovered as the miracle solution to these pollution complications. However, it doesn’t work as well as designed and triggers more complications than it handles, which is why we will find out today when changing the particulate filter of a Toyota Scion FR S? . To do this, first of all, we will identify what the particle filter on your car is used for, and then when to change the particle filter on your Toyota Scion FR S.
What’s the purpose of a Toyota Scion FR S’s particulate filter?
So we start our article with the explanation for this element recently built in into diesel vehicles. As we outlined briefly in the introduction, the purpose of this filter was to resolve the complications of pollution and harmfulness of exhaust fumes from Toyota Scion FR S vehicles. Its operating principle is to store exhaust fumes that are unburned or that still contain harmful particles, and when it is at a adequately high temperature to cause a second combustion that will finish burning and get rid of all these carcinogenic particles. Regrettably, to reach this very high engine unit temperature, you have to be on the highway or have your Toyota Scion FR S engine unit revving up. So we have noticed with time that cars that are specifically on short trips or in the city do not enable the particulate filter to burn these fumes and we will observe in the next part that these complications can force you to change the particulate filter of your Toyota Scion FR S .
When to change the particulate filter of a Toyota Scion FR S?
In this section we will identify what you are most definitely attracted to here, whether it is required to change the particulate filter of a Toyota Scion FR S and if so, when?
Is it required to change the particulate filter on Toyota Scion FR S?
There are 2 types of particulate filter for cars, a particulate filter with additive, which does not matter the Toyota Scion FR S, 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 interested in today, works with precious metals that will produce a chemical reaction at high temperature and cause the regeneration of the filter and the evacuation of the carcinogenic materials. However, as described 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 Toyota Scion FR S as a result of your particulate filter, do not think twice to check out our article on this subject to identify what the process is.
When to change the particulate filter of a Toyota Scion FR S?
As we defined just before, a particulate filter is designed to last the life of the car, nevertheless some of you may wonder when it is required to change the particulate filter of its Toyota Scion FR S?

If you don’t regularly take the motorway, we advise 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 complications, 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 .
