The cleaning process is very labour intensive so if you choose to get it done by your mechanic, expect to add another $500-1000. The EGR valve block off is actually illegal here (not sure in NZ) but that is up to you on that. That is why I suggested a good quality oil catch can as it removes the majority of the oil vapour before it goes through the intake system.

Dont know if its legal here, heaps of people do it & I even talked to my mechanic about it before, he said "if its running ok, leave it alone, our work truck toyota ute has the EGR running & has done over 350'kms"

Maybe Ill ask for a quote for the intake,,,

Don't think there is any additive that will do that. Low ash full synthetic oil will certainly help along with 7,500k oil changes.

A good run occasionally on a motor way or road where you can do at least a constant 80kph for 8 to 10k is not a bad idea.

ENVIRO+ DPF CLEANER | Penrite Oil

https://www.penriteoil.com.au/products/enviro-dpf-cleaner

Enviro+ DPF Cleaner is a Patented, liquid bimetallic platinum cerium catalyst, diesel fuel additive specifically formulated to clean blocked DPF's (Diesel Particulate Filters) as well as improve the operation and reduce maintenance of the DPF emissions control systems in diesel engine applications. Its formulation is soluble and stable in traditional diesel bio-diesel fuels. It cleans and assists in regeneration of diesel particulate filters (DPF's), reduces engine particle matter, cleans injectors, improves diesel fuel combustion improving fuel economy, engine efficiency and maximising catalyst life. Application Enviro+ DPF Cleaner detergents clean deposit build up on the injectors ensuring an even spray pattern. This ensures fuel flow is optimised and assists a uniform burn in the combustion chamber, avoiding power loss. The combustion chamber surfaces are conditioned with active metals to promote a uniform flame front throughout the combustion cycle. This allows a faster burn at lower temperatures and also improves engine efficiency. Enviro+ DPF Cleaner reduces engine particulate matter by up to 20% with ULSD (Ultra Low Sulphur Diesel) and 30% with B20/ULSD (Bio / Ultra Low Sulphur Diesel), so there is less soot (which when burnt accumulates as ash) to collect in the DPF. It initiates passive regeneration (soot oxidation) at lower temperatures and more complete regeneration replacing the need to remove and clean the DPF or replace it completely from high soot loading. Enviro+ DPF Cleaner improves fuel combustion which means less soot accumulation on turbo charger and other combustion exhaust components. Each soot particle emitted from the engine enters the exhaust system coated with our patented bimetallic formulation including two active metals. The active metals work synergistically to oxidize the soot particles and to regenerate and maintain a catalyst coating on the diesel particulate filter with regular use. Enviro+ DPF Cleaner lowers soot oxidation temperature allowing regeneration at lower temperatures preventing run-away regeneration which can otherwise damage the integrity of the substrate and shorten the life of the DPF. Enviro+ DPF Cleaner improves fuel economy by up to 8% (or more depending on engine and application) Enviro+ DPF Cleaner is designed for use to work with diesel fuelled vehicles machinery that are fitted with a diesel particulate filter and or use Penrite Enviro+ diesel engine oils* or Penrite Convoy low Ash oils. PLEASE NOTEEnviro+ DPF Cleaner is designed to be used in passenger cars, light and heavy duty commercial vehicles, trucks, buses other machinery fitted with a DPF (Diesel Particulate Filter). Its maximum benefits are derived from vehicles that are fitted with these filters. We do not recommend this product for use in vehicles not fitted with DPF's, although it will not harm these vehicles or diesel catalysts if fitted to the vehicle. For non DPF vehicles, we recommend Penrite Diesel Injector Cleaner to maintain smooth, consistent performance economy. It is also NOT suitable for use in Peugeot and Citroen vehicles as a replacement for the fluid used in their electronically controlled fuel additive dosing systems. How to Use Add to tank prior to filling with fuel. Add 375ml to 30 litres of diesel fuel for regeneration assist on 1st stage filter blockage (Warning Light). For blockage prevention maintenance, add 375ml for every 60 litres of diesel. Recommended every 5,000 km and at every engine service period. Can be used at each fill of fuel for maximum benefits if needed. Please Note: If your vehicle is fitted with a Capless Fuel Filler system, we recommend using the vehicles emergency fuel filling funnel when adding this product to the fuel tank.

look at this stuff, no idea if it works,,,

Nothing can clean a blocked DPF except taking it off and trying to clean it. Some here have tried with mixed success.

Popped into SuperCrapAuto today to get some oil, they had this on special, 2 for $10, thought Id give it a bash.
