Ways you can work around this issue: Do not fill up the tank to the full 8 gallons. For much more information on DEF see this link.ĭoes DEF Expire?: YES as it has a useful life and then degrades quicker the warmer the climate it is stored in. It has to be at this ratio for maximum effectiveness and lowest freeze point (-11 degrees C). Reason why is that it is a solution and the Jeeps system can tell if it’s old fluid or not of this standard (solution is 32.5% urea and rest water).

DEF fluid you put in should be new (it has a shelf life) and of high quality with API certification to ISO 22241-1 standards. You can fill it up at a service station (some large truck stops have DEF next to diesel) get it from the dealer (they sell 2.5 gallon) for $20 (they can change it for you). You can check the fluid level on the information part of your screen (same screen that shows oil life and battery voltage). If your fluid level is low you may get a Low DEF Fluid Code: P203F. DEF is only required on US and Canadian models where our emissions standards are more strict. In fact the exhaust from a modern diesel is cleaner and emits less CO2 than gas engines of same power (especially where gas engines have direct injection as their NOx emissions are higher than a non-direct injection engine). Emissions Equipmentĭiesel Emission Fluid (DEF): DEF is an reactant (mainly a nitrogen compound that turns into ammonia when heated) that is added downstream (injected into a mist by the DEF injector) to the SCR (selective catalyst reduction) part of the exhaust system where the fluid reacts with NOx compounds to create nitrogen and oxygen. – And all this cost $5-$10k cheaper than the next comparable diesels on the market M元50 BlueTec and X35d. – Full air suspension (rear with trailer package and full with Off Road II or Overland or higher models) – Real 4×4 capability if you option up to the Quadra Drive II option with Off Road Adventure package – Maintenance required is only oil changes and serpentine belt (no spark plugs or timing belts to be replaced). – 10k Maintenance intervals for oil and DEF – Bladder bursting range of up to 800 mile from a 24.6 gallon tank (6 more than the WK CRD) – Shell Track to Track Challenge where a Hypermiler drove 1,100 miles from Autobahn (which is right next to Chicagoland Speedway) in Joliet, IL to COTA in Austin, TX and was able to get 44.4 mpg!!! – get high 20’s / low 30’s real world MPG (EPA is done in a lab on a roller so gas engine EPA #s are overly optimistic) – actually make it easy to park in garages or parking lots without needing 3+ point turns (and also having a small turning radius) So for ~ $40k MSRP (2wd limited without options) you get an SUV that can do the following: Most importantly US and CDN consumers now have a much cheaper mid-size SUV alternative than having only to rely on the Germans. So in Fall 2013 Jeep once again began shipping another diesel powered Grand Cherokee to US and CDN consumers. This however did nothing to curb the following the WK CRD had (including me). Jeep used to have a diesel Grand Cherokee (WK) which they sold from 2007 – 2008.5 but Chrysler’s financial woes and a new Tier 2 Bin 5 EPA emission requirement starting in 2009 put the diesel option back on the bench.
