Re: Anyone with Exhaust Filter problems

The last time I checked BP Ultimate Diesel was brave enough to claim sulphur content at 5ppm. Others claimed 8 or ≤10ppm. But it's not just the carbon. Carbon is supposed to burn up in the DPF but ash can't burn. Ash just builds up. That is why it is so important to use low ash oil and avoid oil or fuel additives even those claiming to be DPF freindly.

Re: Anyone with Exhaust Filter problems

Does Jeep Australia actually make a recommendation regarding Diesel ? For example is just plain old Ultra low sulphur Diesel (normal Diesel in Aus) or would a Premium Diesel like Vortex or Ultimate be preferable?
Ultimate claims less than 0.001 typical ash content up to Max if 0.01 %

I wonder whether the additives included in Diesel fuels which claim to remove buildup of 'deposits' and clean the engine might be contributing to DPF filling up. Your engine will be clean but your DPF will be full of whatever was 'cleaned' out of the engine.

Re: Anyone with Exhaust Filter problems

I have been using Vortex since day one, with a minor top up of BP once. 9 months later and there has been no DPF related issues.
