We use this stanadyne formula every time we head to the pumps, with my high mileage 2011 A3 TDI or my husband's 2009 Jetta TDI (4oz/tank), to maintain performance and longevity. Europe has higher-quality fuel, while our diesel in North American has lower cetane levels, higher water content and removed lubricity, which can cause injector wear and reduce efficiency. Stanadyne addresses these concerns and many others. I trust this additive to provide smoother operation and long-term reliability. My husband says he gets better fuel economy, but that isn't a quality I'm concerned about with my CR170.
Tip: we use the bottle pictured to pre-measure the additive before we go fuel up.
Diesel Parts Canada always has it in stock, it ships quickly and is on my doorstep in no time!
Whether you have a vehicle from across the pond or one that was built domestically, stanadyne should be in your tank!
What the DPF?!?
Diesel Particulate Filters were introduced as away for the OEM to meet government mandated emission standards. Diesel particulates are trapped in the filter and build up over time. Most DPF systems require a "filter regeneration" which is a process that burns off the buildup of particulates in filter. This "regeneration" occurs while driving at highway speeds which can be a problem for vehicles which are used for commuting in city traffic. If a driver ignores the warning light and continues to drive without doing a "regeneration" this can result in the engine derating, an improper "regen" or a complete failure of the DPF. There are different signs that may indicate that there is a problem with your DPF:
