We suggest choosing from the larger fuel companies, the more well known the better. Try to avoid stations at the bottom of a hill as they can collect water at the top of their tanks. Even though they dip them, a lot of people do not report the water ingress correctly. Do not fill up when a fuel delivery truck is filling the station. During the filling process, the sediment and water in the tank is agitated and mixes with the fuel, and that's what will be pumped into your rig. It's best to wait until the next day so the sediment and water settles. Other than that there is not much else you can do.
The off-road is dyed red, that's all.
Unfortunately for the manufacturer (and us), the Clean Air Act has set some pretty strict rules to abide by, it is not an option but a requirement. The emissions systems need to be installed and working correctly with no defeat devices being used to be compliant so they can sell their vehicles in the US and other countries. California for example has the highest restrictions in the country, they are basically setting the standards for the US through C.A.R.B. Unfortunately this is something we are going to have to deal with as consumers if we want the power and torque of a diesel engine. Otherwise, diesel will be a thing of the past.
Do not delete your truck. There are many reasons for this. 1. It is illegal, can come with heavy fines and possible prison time. 2. Poor delete tuning can cause catastrophic engine and transmission damage. 3. The emissions system acting up is usually a sighn of an underlying engine problem. 4. It will void your warranty.
TA's as long as its name brand it doesn't matter. It just has to meet the standards.
At Flying Wrench, we use the Shell Rotella line because of its broad API coverage. For synthetic we stock T-6 and for conventional we stock T-4. Any brand is fine as long as it meets the CK-4, CJ-4, CI-4 PLUS, CI4 and CH-4.
DEF (Diesel Exhaust Fluid) works by injecting a mixture of deionized water and urea into a diesel engine's exhaust system, where it reacts with harmful nitrogen oxides (NOx) through a process called Selective Catalytic Reduction (SCR), converting them into harmless nitrogen gas and water vapor, significantly reducing emissions from the engine.
