Different people will tell you one brand is better than another. All oil is the same to a certain point. After that, manufacturer’s try to make them better. They put their own blend of additives in to withstand heat better, clean, etc. So, pick the one you like.

As far as viscosity, stick with manufacturers recommended viscosity. The tolerances in engine bearings are a lot smaller than they used to be and a thicker oil could cause damage. Plus, it will void your warranty If it’s a new vehicle.

There are a lot of variables at play here. What is the quality of the pads and rotors that you used. Did you even change the pads? What are your stopping habits? Is the truck empty or loaded? All this comes into play. Sometimes all at once. But probably the biggest thing is breaking habits. A ton of folks like to wait till the last possible second to apply their brakes and try to stop in ten feet. What they should be doing is gradually slowing by gently applying the brake. Give yourself a lot of room to stop. Your brakes and your wallet will thank you.

The P0420 DTC is generated by the rear (downstream) HO2 Sensor when it
senses too much leftover oxygen after the catalytic converter does its job.
This causes the sensor to “switch” high-low just like the upstream HO2
sensor. Sometimes there may be a misfire or a lean condition like a manifold
leak which causes this DTC. More often we find the catalyst is just worn,
coated or deteriorated from long use and having had the above-mentioned
upstream defects at one or more times in its life. That’s one good reason
why it is so important to promptly fix any misfires, rich or lean
conditions!

If you are satisfied the upstream problems are repaired, it’s time to
replace the cat.

The Dakotas have a single rear ABS sensor, which is mounted in the top of the differential housing.

I would recommend that you re-check the application for that new switch
(light only, light + gauge, gauge only) Whatever is causing it, it is a
short to ground in the circuit to the sender when the gauge goes to the top
of the range immediately upon KOEO (key on engine off).
