I read a smilar post from yesterday. My question is a little different. My Yukon XL has 50K and runs great. However, due to the industry that I am in, I have been given 4 new O2 sensors but have not put them in.

 

Should I go ahead and replace them now or hold these new O2s until I have more miles on the clock?

 

If I do decide to replace them, should I replace all 4 at one time or should I change one, drive it a few days, change another and repeat until I have all four changed? I was just concerned that replacing all four at once my set some type of code.

Good advice. My Dad is 67 and I have heard him say this several times. I have an addiction to "piddlin". Just like changing my plugs and wires a couple of weekends ago. At 50K I know this was unecessary but I enjoyed doing it. And besides, now I have those cool Red Wires. The red color alone is good for at least 10 HP. :banghead:

You changed yoru wires and got 10 more horses? Kool where can i get these wires? What kind are they?

Roy, the ten horses came from the wires being red. I was really just joking about the 10 horses. However, I will tell you that I have an Interceptor Scan gauge that has a HP calculation feature. Previous to the new wires and plugs, it would read 302 HP at shift point. It read 309 after the wire and plug change. I did not run it just before the change. The previous test was on a 70 degree day. The day I did the wires, and checked the HP again, it was about 50 or maybe a little less. This would likely explain the increase. Also, the Interceptor is no dyno, it just calulates off air flow, fuel, air temp etc.

 

The wires were Taylor 8.2 PowerVolts, and some do claim that really good wires can provide a little HP. I am not sure if the wires and/or air temp did mine, but the wires are great quality and they look really nice also.

It is my understanding that Blue wire will get you at least 20 and if you put the decal that came with them in your back window, it will get you anothrer 10. :)

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
