My truck is a 2000 Sierra (4.8L) 4X4 and I now live in GA and have to go through emissions testing (great!). I bought this truck new and it has been with me ever since. My military career kept me away from it for long periods of time and the end result is a 7 year old truck with only 48,000 miles on it :cheers:. My question is when would be a good time to change the Catalytic Converters? When I was stationed in Texas, I was going to change them out and a reputable exhaust shop told me they wouldn't recommend it before 50,000 miles. I really don't fear failing the emissions test, just curious as to when I should replace them. The truck has never thrown any codes and I have done some mods to it.

 

Thanks

I've never heard of replacing them unless they are clogged. There's really no point. When they clog you'll know it as it will feel like your pulling a 10k lb trailer (i.e. high RPM's and no go).

Niceeeee Truck .. your brush-guard - manufacturer ??

 

Thanks for the complement. I bought the brush guard from Four Wheel Parts almost six years ago. I think it was a Genuine Steel name brand. I got a killer deal on it. I only paid $250 for it and they threw in the KC Daylighter Fog Lights (because they ordered me the wrong brush guard and I had to send it back). Anyway, it has held up great for those years I spent in the Texas heat. I also ordered stronger tow hooks and put those in place of the factory ones when I installed the brush guard.

I figured as much. I guess I can wait on the Magnaflow Cats a little while longer. Thanks for the info!

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Z45 · Posted

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      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.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
